2,955 drug poisoning deaths (involving both legal and illegal drugs) were registered in 2013 in England and Wales (2,032 male and 923 female deaths)
Male drug poisoning deaths increased by 19% compared with 2012. Female drug poisoning deaths have increased every year since 2009
Male drug misuse deaths (involving illegal drugs) increased by 23%, from 1,177 in 2012 to 1,444 in 2013. Female drug misuse deaths increased by 12%, from 459 in 2012 to 513 in 2013
Heroin/morphine remain the substances most commonly involved in drug poisoning deaths. 765 deaths involved heroin/morphine in 2013; a sharp rise of 32% from 579 deaths in 2012
Deaths involving tramadol have continued to rise, with 220 deaths in 2013. This is almost 2.5 times the number seen in 2009 (87 deaths)
There was a sharp increase of 21% in the number of drug misuse deaths in England in 2013, with no change to the number of these deaths in Wales. However, mortality rates from drug misuse were still significantly higher in Wales than in England
Male mortality rates significantly increased in three substance categories: heroin/morphine, benzodiazepines and paracetamol. Conversely female mortality rates remained relatively stable except for a sharp increase in the cocaine-related death rate
In England, the North East had the highest mortality rate from drug misuse in 2013 (52.0 deaths per million population), and London had the lowest (23.0 deaths per million population)
All figures presented in this bulletin are based on deaths registered in a particular calendar year. Out of the 2,955 drug-related deaths registered in 2013, 1,488 (just over half) occurred in years before 2013
This bulletin presents the latest figures from the Office for National Statistics (ONS) on deaths related to drug poisoning (involving both legal and illegal drugs) and drug misuse (involving illegal drugs) in England and Wales for the last five years (2009 to 2013). Figures from 1993 are available to download, and are discussed in the commentary to provide further context to the latest (2013) data. Figures presented in this bulletin are for deaths registered each year, rather than occurring each year. See the ‘Impact of registration delays on drug-related deaths’ section below for more information. Figures are given by cause of death, sex, age, substance(s) involved, and area of usual residence of the deceased.
Two revisions to methodology were implemented in 2014:
- The introduction of a revised method for calculating age standardised rates using the new 2013 European Standard Populations (ESP)
- The inclusion of 20 extra drugs to the drugs misuse definition, following their addition to the list of substances controlled under the Misuse of Drugs Act 1971
A back series has been provided for the 2013 ESP age standardised rates, and all rates figures in this report are calculated using the revised method. All figures for drug misuse in this report are based on the revised drugs misuse definition and a back series has also been provided. A separate set of reference tables with figures calculated using the previous misuse definition are available on the ONS website. For full details see section on methodological changes.
There were 2,955 drug poisoning deaths (involving both legal and illegal drugs) registered in 2013, and, as in previous years, just over two-thirds of these deaths were in males. There were 2,032 male deaths from drug poisoning in 2013, an increase of 19% since 2012, and the highest since 2009.The equivalent number of female deaths was 923, an increase of 4% since 2012, and the highest since 2004.
In 2013 males aged 30 to 39 had the highest mortality rate from drug misuse (130.7 deaths per million population), followed by males aged 40 to 49 (108.3 deaths per million population). The male mortality rates in these two age groups were significantly higher than the rates in all other age groups, and much higher than for females of any age.
The highest mortality rates for females were among those aged 40 to 49, followed by those aged 30 to 39 (33.5 and 33.1 deaths per million respectively). These rates were significantly higher than the rates in other age groups.
Over half (56%) of all deaths related to drug poisoning in 2013 involved an opiate drug. In men aged 30 to 39, over two thirds (68%) of drug-related deaths involved an opiate. In 2013, as in previous years, the most commonly mentioned opiates were heroin and/or morphine, which were involved in 765 deaths.
Deaths involving heroin/morphine increased by 32% in 2013 to 765, up from 579 deaths in 2012. Meanwhile deaths involving tramadol, a synthetic opiate, have also continued to rise. There were 220 deaths in 2013, an increase of 26% from the 175 deaths in 2012. This is now almost 2.5 times the number recorded in 2009 (87 deaths). The number of deaths involving new psychoactive substances (sometimes referred to as ‘legal highs’) increased by 15% in 2013, with 60 deaths, up from 52 deaths in 2012. However, this increase was not as steep as that observed between 2011 and 2012.
The number of drug misuse deaths in England and Wales increased by 20% in 2013 to 1,957 deaths, from 1,636 in 2012. However, this increase was not consistent nationwide. There were 1,812 drug misuse deaths in England, an increase of 21% in 2013 from 1,492 in 2012. In Wales there were 135 deaths, the same number recorded in 2012. However, mortality rates from drug misuse remained significantly higher in Wales than in England, despite rates in England increasing significantly, from 28.0 deaths per million population to 33.9 in 2013.
The differing trends between England and Wales is particularly apparent in the number of female drug misuse deaths. In England the number of these deaths increased by 14% between 2012 and 2013, whilst there was a 11% decrease in the figures for Wales. However, the number of female drug misuse deaths in Wales are small (35 in 2012 and 31 in 2013), so these figures should be treated with caution.
Within England the drug misuse mortality rates vary considerably. The North East had the highest mortality rate from drug misuse in 2013 (52.0 deaths per million population), whereas London had the lowest (23.0 deaths per million population).Back to table of contents
Drug use and drug dependence are known causes of premature mortality, with drug poisoning accounting for nearly one in seven deaths among people in their 20s and 30s in 2013 (see Background note 7). Drug-related deaths occur in a variety of circumstances, each with different social and policy implications. Consequently, there is considerable political, media and public interest in these figures.
This bulletin covers accidents and suicides involving drug poisonings, as well as deaths from drug abuse and drug dependence. It doesn’t include other adverse effects of drugs (for example, anaphylactic shock). Drug poisoning deaths involve a broad spectrum of substances, including legal and illegal drugs, prescription drugs (either prescribed or obtained by other means) and over-the-counter medications. Some of these deaths may also be because of complications of drug abuse, such as deep vein thrombosis or septicaemia from intravenous drug use, rather than an acute drug overdose.
The figures presented here are for deaths registered each year, rather than deaths occurring each year. Almost all drug-related deaths are certified by a coroner. Due to the length of time it takes a coroner to complete an inquest, just over half of drug-related deaths registered in 2013 will have actually occurred prior to 2013. See the ‘Impact of registration delays on drug-related deaths’ section below for more information.Back to table of contents
ONS have implemented a revision to the definition of the drugs misuse indicator for the 2013 data onwards and a back series has been provided for comparison purposes. The definition of this indicator includes (a) deaths where the underlying cause is drug abuse or drug dependence, and (b) deaths where the underlying cause is drug poisoning and where any of the substances controlled under the Misuse of Drugs Act 1971 are involved. This definition has been adopted across the UK.
To ensure the drug misuse data reported in this bulletin includes deaths involving all drugs recently added to the list of substances controlled under the Misuse of Drugs Act 1971, 20 new drugs have been added to the definition. These include tramadol and 3,4-methylenedioxy-N,N-dimethylamphetamine (MDDA). For the full list of additional misuse drugs included in the revised definition see Background note 6. Figures for all previous years (1993 to 2012) have been revised to allow comparison for statistical purposes across the entire time series.
Inevitably, this revision has caused the number of drug misuse deaths in England and Wales to increase, with the increase being greatest in the most recent years. For example, only three additional deaths were classified as due to drug misuse in 1995, rising to an extra 140 in 2012.
The revision has also led to drug misuse mortality rates increasing over the time series, as there are more deaths related to these newly classified drugs with no change to the underlying population estimates. The largest increase in the drug misuse mortality rate for regions was in Yorkshire and Humber in 2012 (30.1 to 33.8 deaths per million population in 2012) and the East Midlands (from 20.7 to 23.8 deaths per million population in 2012). Additionally, for both males and females, the largest increase in the mortality rate occurred in the 40 to 49 age group.
All figures for drug misuse have been calculated using the revised drugs misuse indicator. A separate set of reference tables with figures calculated using the previous misuse are available on the ONS website.
2013 European standard population
The European Standard Population (ESP) is an artificial population structure used to weight mortality or incidence data to produce age-standardised rates, to comparisons across populations that may have different age and sex structures. The 2013 ESP takes account of changes in the EU population, providing a more current, methodologically sound and acceptable basis to calculate age standardised rates (Office for National Statistics). The previously used 1976 ESP and the 2013 ESP differ in two ways. Firstly, the 2013 ESP gives the populations in older age groups greater weighting than the 1976 ESP. Secondly, the age distribution of the 1976 ESP had an upper limit of 85 years and over, while the 2013 ESP is further disaggregated to include age groups 85 to 89, 90 to 94 and 95 and over. However, since population estimates of assured quality are not readily available for the 95 and over age group, and differences between ASRs calculated using 90+ and 95+ as the upper age group are not significant (for either sex), ONS recommends that National Statistics outputs are produced using the 2013 ESP with the 90-94 age group aggregated to 90 and over.
The impact of implementing the 2013 ESP has been that that drug poisoning mortality rates have increased slightly for females over all years with the largest increase in 1993 of 3.3 deaths per million population. For males the difference ranges from a decrease of 2.2 deaths per million population in 1998 to an increase of 0.9 deaths per million in 2011. For drug misuse, again the rates for females increased in every year with the largest increase in 1993, of 1.1 deaths per million. For males, the mortality rate related to drug misuse decreased in every year, with the largest decrease in 2002 of 3.2. This is because the 2013 ESP gives a higher weight to those in the higher age groups. Males dying due to drug poisoning tend to be younger than females which explains the different impact for the different sexes. When looking at the figures for substances mentioned on death certificates, the female mortality rate with the largest change was for paracetamol in 2004, an increase of 1.4 deaths per million. For males the largest change was for heroin/morphine in 2001, a decrease of 2.4 deaths per million. Again this will relate to the age groups most associated with these substances.
All age standardised rates in this report have been calculated using the 2013 ESP, with revisions provided back to 1993. ONS have published a study on the impact of calculating mortality rates using the 2013 European Standard Population on causes of death.Back to table of contents
The current Government drug strategy, 'Reducing demand, restricting supply, building recovery: supporting people to live a drug-free life' (Home Office, 2010), highlights preventing drug-related deaths as one of the key outcomes that recovery-oriented services should be focused on. In April 2013 responsibility for public health – including drug and alcohol prevention and treatment – passed from the NHS to local authorities.
Patterns of drug use change over time. For instance, in recent years people have been taking new psychoactive substances, including so-called ‘legal highs’. In response to this, a Government review of NPS looking at the nature of the market and legislative and operational responses is due to report this year. There is also an increased emphasis on drug prevention alongside drug treatment across all substances and drug using cohorts. Misuse of prescription drugs continues to attract attention and tighter prescribing rules for tramadol were introduced in 2014.
In February 2013, the Welsh Government published the Substance Misuse Delivery Plan 2013–2015 (Welsh Government, 2013), which included the specific target of ‘reducing the number of substance misuse related deaths and non-fatal overdoses/alcohol poisonings in Wales’. To support this, guidance for undertaking fatal and non-fatal drug poisoning reviews has been developed and is now available on the Welsh Government website. The Welsh Government are now working with partners to implement the guidance.Back to table of contents
The figures contained in this bulletin are used by a range of public bodies, such as Public Health England (PHE), the Department of Health (DH) and the Welsh Government to evaluate the effectiveness of various drug strategies.
In April 2013, the key functions of the National Treatment Agency for Substance Misuse were transferred into PHE, and they have linked ONS data on drug-related deaths with data from the National Drug Treatment Monitoring System (NDTMS). This is to investigate the timing of drug-related deaths in relation to treatment history. This research will also examine risk factors associated with these deaths and carry out comparisons of areas.
The Welsh Government and Public Health Wales are linking ONS data to information on the distribution and coverage of the National Take-Home Naloxone (THN) programme. This will be used to evaluate whether the THN program is having an impact on the number of drug-related deaths in Wales, and also to identify areas requiring further focus.
The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) combines data for England and Wales from the ONS drug poisoning database with data from Scotland and Northern Ireland to publish UK figures. This allows comparisons to be made with other European countries. The 2013 EMCDDA statistical bulletin shows that the drug-related mortality rate in the UK was the fourth highest in Europe (EMCDDA, 2013). However, caution should be applied when making international comparisons, because of differences in definitions and the quality of reporting.
ONS drug poisoning data are also used by academic researchers. For example, analysis of this data by the Centre for Suicide Research at the University of Oxford revealed that there was a major reduction in deaths involving co-proxamol following its withdrawal in 2005, with no evidence of an increase in deaths involving other analgesics, apart from oxycodone (Hawton et al, 2012). Updated data on deaths involving co-proxamol and other analgesics are shown in Reference Table 6a.Back to table of contents
There were 2,955 drug poisoning deaths (involving both legal and illegal drugs) registered in 2013. This is the highest since 2001, and represents an increase of 14% since 2012. As in previous years, the majority (just over two-thirds) of these deaths were in males. There were 2,032 male deaths from drug poisoning in 2013, an increase of 19% since 2012, and the highest since 2009. The equivalent number of female deaths has been steadily rising since 2009, and rose to 923 in 2013. This is an increase of 4% since 2012.

Over half (56%) of all deaths related to drug poisoning in 2013 involved an opiate drug. In men aged 30 to 39, over two thirds (68%) of drug-related deaths involved an opiate. In 2013, as in previous years, the most commonly mentioned opiates were heroin and/or morphine, involved in 765 deaths (see Background note 8). The number of deaths involving heroin and/or morphine had steadily declined between 2009 and 2012. However, in 2013 the number of deaths increased by 32% from 579 to 765 deaths. This increase brings the number of deaths relating to heroin and/or morphine to levels similar to 2010.
Evidence suggests that in 2010/11 there was a ‘heroin drought’ in the UK, with reduced availability of heroin persisting in some areas in 2011/12 and 2012/13 (SOCA, 2011, 2012, 2013, 2014). In recent years there has been a change in the purity of street heroin. SOCA reports claim the street purity of heroin fell from 46% in September 2009 to around 15% to 20% in 2012/13, before increasing again in 2013/14 to 25% (SOCA, 2011, 2012, 2013, 2014). This increase in street purity after a time of lower purity may partly or wholly explain the increase in heroin related deaths in 2013, as users may have had reduced tolerance to the drug.
The mortality rate for males in 2013 increased significantly by 43%, to 21.8 from 15.2 deaths per million population in 2012. Since 2010 the mortality rate had decreased and this reversal brings the mortality rate closer to levels previously seen before the ‘heroin drought’. However, even with this increase, the mortality rate still remains lower than in 2010.
The female mortality rate for deaths involving heroin/morphine has been gradually increasing since 2010, and reached the highest rate on record (since 1993) in 2013, with 5.4 deaths per million population. Although the female mortality rate continues to rise it remains significantly lower than the male rate.
Public Health England (2013a) report that the number of people starting treatment for heroin and/or crack addiction (including those returning to treatment) fell from 64,288 in 2005-06 to 47,210 in 2011-12 falling further to 45,739 in 2012-13 (Public Health England, 2013b). However, evidence from the Crime Survey for England and Wales (Home Office, 2012) suggests generally there has been little variation in heroin use year-on-year since their measurement began.Back to table of contents
In 2013 there were 429 deaths involving methadone, an opiate substance used to treat heroin addiction which is sometimes abused. The number of deaths caused by methadone is fairly variable and this number does not appear unusual. The male mortality rate for deaths involving methadone increased slightly from 11.0 deaths per million population in 2012 to 11.5 in 2013. The equivalent rate for females in 2013 remains the same as in 2012, at 3.7 deaths per million population.Back to table of contents
There were 169 deaths involving cocaine in 2013, an increase of 22% from 139 deaths in 2012. However, the number of deaths involving cocaine have been variable over the last few years, with a peak in 2008 of 235 and a low of 112 in 2011. The male mortality rate declined significantly between 2008 and 2011 by over a half, but has since increased to 4.8 deaths per million population in 2013. The equivalent rate in females has continued to be significantly lower than for males despite a 57% rise (from 0.7 to 1.2 deaths per million population in 2012 and 2013 respectively). Recent Home Office reports suggest that in 2013/14, the proportion of adults aged 16 to 59 using powder cocaine was higher than in 2012/13 (1.9%), although this remains lower than the peak of 3.0% in 2008/09 (Home Office, 2014a).Back to table of contents
The number of deaths involving amphetamines increased from 97 in 2012 to 120 in 2013, which is the highest number of deaths since records began in 1993. In addition to amphetamine itself, the amphetamines group includes substances such as methylenedioxymethamphetamine (MDMA, also known as ecstasy), methylamphetamine, paramethoxyamphetamine (PMA) and Para-methoxymethamphetamine (PMMA).
The number of deaths involving MDMA/ecstasy have varied across the years, with a decrease from 58 in 2005 down to 8 deaths in 2010. Since then the number of deaths have gradually increased to 43 deaths in 2013. The Home Office reported a rise in ecstasy use by adults aged 15 to 59 between 2013 and 2014 (Home Office, 2014a).
Reports have expressed concerns about the availability of ‘super strength’ ecstasy with one recent formulation having a reported MDMA content around 2-2.5 times the standard MDMA dose per pill (Drugscope, 2014). This may partially explain the increased number of deaths involving MDMA/ecstasy. However, the impact of any recent changes in strength may not be fully captured in this bulletin, as deaths occurring in 2014 are not included in this report.
There has also been a large increase in the number of death certificates mentioning PMA or PMMA since 2011. These substances were only involved in one death in 2011, but were involved in 29 deaths in 2013 (a small number of these deaths also mentioned ecstasy). It has been suggested that people may be ingesting PMA/PMMA in the belief that they are taking ecstasy tablets (Frank, 2013). However, there is not enough information recorded on coroners’ death certificates to confirm if this was the case for the deaths registered in 2013.Back to table of contents
Over the past few years a number of new drugs have been informally categorised as ‘legal highs’. These include synthetic cannabinoid receptor agonists (for example, ‘spice’), gamma-hydroxybutyrate (GHB) and its precursor gamma-butyrolactone (GBL), piperazines (benzylpiperazine – BZP and trifluoromethylphenylpiperazine – TFMPP), cathinones such as mephedrone, and pipradrols such as desoxypipradrol. Most of these substances are now controlled under the Misuse of Drugs Act (1971). These will all be referred to as new psychoactive substances (NPS) in this report. There is no official definition of ‘legal highs’ or NPS, although all drugs included in the NPS definition for the purposes of this bulletin are listed in Background note 11. This grouping may be revised in future years, as and when further NPSs are identified. The number of deaths involving NPS are low compared with the number of deaths from heroin/morphine, methadone and cocaine poisoning. However, over the past few years there has been an increasing trend in NPS deaths with sharp increases between 2011 and 2012 (29 to 52 deaths). The number of deaths involving NPS rose again in 2013 by 15% to 60 deaths. This increase is not as steep as previously seen, although it is too early to say whether the rise is stabilising.
The number of deaths involving cathinones (including mephedrone) continued to rise in 2013 , to 26 deaths. This was a rise of 44% from the 18 deaths in 2012, which was over four times greater than the 6 deaths in 2011. It may be that the number of users is increasing as the number of people seeking treatment for NPS has increased significantly. For example, those seeking treatment for mephedrone use rose from 900 new cases in 2012 to 1,630 in 2013 (Public Health England, 2013b). This was despite evidence from the Crime Survey for England and Wales suggesting that the proportion of 16 to 59-year-olds using mephedrone in 2012 has declined since 2010/11 (Home Office, 2013).Back to table of contents
There were 342 drug poisoning deaths involving benzodiazepines in 2013, a 20% increase from 2012 and the highest number of deaths since records began in 1993. The number of deaths involving benzodiazepines in 2013 was almost double the historic low of 177 deaths in 2006.
Mortality rates in males increased significantly from 7.1 in 2012 to 9.4 deaths per million population in 2013; the highest rate since records began. Equivalent mortality rates in females were significantly lower than in males at 2.9 deaths per million population in 2013, with no rate change compared with 2012.
In addition to benzodiazepine itself, the benzodiazepines group includes substances such as diazepam and temazepam. Diazepam was the most common type of benzodiazepine mentioned on deaths certificates in 2013, involved in 228 deaths, the highest number on record. The increase in deaths involving diazepam is consistent with a survey suggesting that there has been a continued increase in the use and availability of illicit benzodiazepines, such as diazepam (Daly, 2012). However, the role of diazepam and other benzodiazepines in drug-related deaths is unclear, as more than 9 out of 10 deaths involving benzodiazepines also mentioned another drug.
Temazepam is also a common benzodiazepine mentioned on death certificates; the number of deaths has gradually decreased since records began. In 2013 there were 31 deaths, the lowest on record, which is less than half of that seen in 2004 (78 deaths) and a fifth of that seen in 1995 (159 deaths).Back to table of contents
The number of deaths involving zopiclone or zolpidem has steadily increased since 1993 to 86 deaths in 2013. In June 2014, zopiclone was controlled under the Misuse of Drugs Act 1971 as a class C substance (Home Office, 2014b).Back to table of contents
There were 466 deaths involving antidepressants in 2013, comparable with the number in 2012. Male mortality rates increased slightly from 8.0 to 9.3 deaths per million population in 2013 (the highest since 2004). Female mortality rates fell from 8.9 in 2012 to 7.5 deaths per million population in 2013, following a large increase in the previous year.
Deaths across the different antidepressants were quite variable in 2013. Deaths involving tricyclic antidepressants (TCAs) showed little change from 2012, with 235 deaths. The majority of the TCA deaths involved amitriptyline where there was a 12% rise to 173 deaths, continuing the upward trend since 2010. Conversely, deaths relating to dothiepin decreased by 41% from 51 deaths in 2012 to 30 deaths in 2013, continuing the broadly downward trend since 1994. Although TCAs are still involved in more deaths than other types of antidepressants, the number of deaths from TCA poisoning is now much lower than its peak of 497 deaths in 1998.
Deaths involving Selective Serotonin Re-uptake Inhibitors (SSRIs) had been steadily increasing over recent years, reaching a peak in 2012 (158 deaths). In 2013, this number decreased to 150. However this variability is normal for these data, so does not necessarily indicate a levelling off in deaths.
The majority of SSRI deaths involve the drug citalopram. The number of these deaths, has been increasing gradually over time, but in 2013 there was a decrease in deaths by 19% to 82 deaths. Studies show that SSRIs are less toxic in overdose than TCAs (Hawton et al, 2010), but SSRIs are prescribed more frequently. In the last five years prescriptions for SSRIs have increased more rapidly than prescriptions for TCAs (Health and Social Care Information Centre – HSCIC, 2010 and 2014), which may explain the gradual long-term rise in deaths involving SSRIs.
Deaths involving other types of antidepressants have continued the upward trend, reaching a peak in 2013 of 123 deaths. Reference Table 6a shows that the majority of these deaths involved venlafaxine or mirtazapine (British National Formulary section 4.3.4, British Medical Association and Royal Pharmaceutical Society, 2013). Only one death involved a Monoamine-Oxidase Inhibitor – MAOIs (BNF section 4.3.2). The number of deaths involving mirtazapine increased by 49% in 2013 to 73 deaths from 49 in 2012, the highest number on record since 1993. Deaths involving venlafaxine have decreased by 14% to 48 deaths in 2013, although this followed a large increase in 2012 of 60%. Over time, the number of deaths involving venlafaxine appears to fluctuate around a consistent level. The National Institute for Health and Clinical Excellence guidelines (NICE, 2009) suggest that these drugs should not be used as a first-line treatment for depression, and should only be prescribed to people who have not responded to SSRIs. Venlafaxine in particular is associated with a greater risk of death from overdose.
Prescriptions for ‘other antidepressant drugs’ like venlafaxine and mirtazapine (BNF section 4.3.4) accounted for only 18% of all antidepressant prescriptions in 2013. However, this proportion has increased from 16% in 2009 (HSCIC, 2010 and 2014), which may partly explain the increase in deaths.Back to table of contents
There were 226 deaths involving paracetamol and its compounds in 2013, an increase of 24% from 182 deaths in 2012. The mortality rates for males and females differed in 2013. There was a large increase in mortality rate for males from 3.1 to 4.9 deaths per million population, whilst female rates remained the same at 3.7 deaths per million population. Looking at the long-term trends, both male and female mortality rates had been decreasing since 2004.Back to table of contents
A notable trend that had emerged in recent years is the steady increase in the number of deaths mentioning tramadol (a synthetic opioid analgesic). This increasing trend started in 1997 and continued into 2013 where the number of deaths involving tramadol increased by 26% from 2012 to a new peak of 220 deaths. There has been a 29% increase in tramadol prescriptions over the last five years (HSCIC, 2010 and 2014). However, the latest ‘Street drug trends survey’ carried out among police forces, drug agencies, frontline treatment services and drug user groups showed the continued rise in the recreational use of tramadol and other synthetic opioids (Daly, 2012). In June 2014, tramadol was controlled under the Misuse of Drugs Act 1971 as a class C substance (Home Office, 2014b).Back to table of contents
There were 62 deaths mentioning helium in 2013, over five times higher than the 12 deaths recorded in 2008 (see Background note 12 for further information on helium deaths). Although the number of deaths involving this substance is still relatively small, the recent increases have been of interest to those concerned with suicide prevention, as almost all of these deaths were suicides. In 2013, the number of deaths involving helium increased by 7% compared with 2012.Back to table of contents
