Scotland Drug Deaths Rise 11% as Nitazene Presence Surges
Scotland recorded a significant increase in drug-related deaths in 2025, with the latest figures showing an 11% rise in fatalities compared with the previous year. The increase comes amid growing concerns over the appearance of increasingly potent synthetic opioids, including nitazenes, in the country’s illicit drug supply.
According to annual figures released by the National Records of Scotland (NRS), there were 1,133 drug-related deaths in Scotland in 2025 — an increase of 116 deaths from the previous year. The total represents the sixth-highest number of drug-related deaths ever recorded in Scotland.
The figures highlight the continuing role of opioids in Scotland’s drug-death crisis, while also pointing to significant changes in the substances appearing in the illicit market.
Opioids Remain the Leading Cause of Drug Deaths
Opiates and opioids, a category that includes heroin and other opioid substances, were implicated in 78% of all drug-related deaths recorded in Scotland during 2025, making them the most commonly associated drug group in fatal cases.
However, one of the most notable changes was the dramatic increase in deaths involving nitazenes, a group of highly potent synthetic opioids.
The number of deaths in which nitazenes were detected increased by more than 200%, rising from 76 deaths in 2024 to 247 in 2025.
Nitazenes are manufactured synthetic opioids rather than substances derived directly from the opium poppy. Some compounds in the group can be extremely potent compared with traditional opioids, creating significant risks when they enter an illicit drug supply.
The substances may also be mixed with or sold as other drugs. This can make them particularly dangerous because people may not know that nitazenes are present in what they are taking.
Officials Warn of an Increasingly Unpredictable Drug Supply
Maree Todd, Scotland’s minister for mental wellbeing, public health, sport, alcohol and drugs, said the latest figures demonstrated the need for a coordinated response to what she described as an increasingly toxic and unpredictable drug supply.
The warning comes after Scotland recorded its lowest number of drug-related deaths since 2017 in the previous year's data. At the time, however, the Scottish Drugs Forum (SDF) cautioned that the decline might not represent a sustained improvement and could instead obscure a growing threat from synthetic opioids.
The organization had previously warned that nitazenes were becoming increasingly prominent within Scotland’s illicit drug market, raising concerns that the country could see renewed increases in drug-related fatalities.
The latest figures appear to underscore those concerns, particularly given the sharp increase in deaths involving nitazenes.
Nitazenes Add New Risks to an Already Dangerous Drug Market
Unlike heroin and other naturally derived opioids, nitazenes are produced synthetically, often in illicit laboratories. Certain nitazene compounds can be substantially more potent than conventional opioids, meaning relatively small quantities can pose serious risks.
Their presence in the illicit drug supply can also be difficult for individuals to detect. Nitazenes may be incorporated into other substances or sold as different drugs, potentially exposing people to powerful synthetic opioids without their knowledge.
Kirsten Horsburgh, chief executive of the Scottish Drugs Forum, said the increase in drug-related deaths was likely influenced by a combination of factors, including changes in the drug supply.
She described the growing presence of nitazenes as a clear indication that the risks associated with Scotland’s illicit drug market are changing.
Horsburgh also cautioned against attributing the 1,133 deaths to a single cause.
She emphasized that fatal drug overdoses are influenced by a much broader range of social and economic circumstances, including poverty, trauma, deprivation, housing insecurity, and inequalities in mental health.
The latest statistics provide evidence of the relationship between deprivation and drug-related mortality. People living in Scotland’s most deprived areas experienced drug-related death rates 15 times higher than those living in the least deprived areas.
Men Accounted for a Growing Share of Deaths
The data also showed a notable increase in drug-related deaths among men.
Fatalities among men rose by 19% in 2025, while the average age at death was 46 years.
The figures highlight the continuing need to address not only the availability and toxicity of drugs but also the wider conditions that can contribute to problematic drug use and fatal outcomes.
The Scottish Drugs Forum has argued that factors such as poverty, unstable housing, trauma, and unequal access to health and support services can all play a role in determining an individual’s vulnerability to drug-related harm.
Government Expands Treatment and Recovery Services
The Scottish government has pointed to increased investment in treatment and recovery services as part of its response to the country's drug-death crisis.
Maree Todd said the government funded more than 1,100 residential rehabilitation placements during 2025 and has expanded access to treatment.
However, she acknowledged that existing measures have not been sufficient to prevent the continuing loss of life.
Todd said that, despite government policies and the work of frontline staff, further action is needed to reduce Scotland’s drug-related mortality.
The latest statistics therefore come at a time when policymakers and treatment providers are facing the dual challenge of improving access to addiction treatment while responding to an illicit drug market that is becoming increasingly unpredictable.
Scotland Continues to Have One of Europe’s Highest Drug Death Rates
The new figures mean Scotland continues to have the highest drug-related death rate in Europe, maintaining its long-standing position at the top of European drug mortality statistics.
The persistence of such high mortality has intensified calls for measures that combine treatment, harm reduction, prevention, and efforts to identify dangerous substances before they cause additional deaths.
The growing presence of synthetic opioids has added another layer of complexity, as the composition of the illicit drug supply can change quickly and expose people to substances they may not expect to encounter.
Drug-Checking Services Expand
Scotland is also expanding its harm-reduction response through drug-checking services designed to identify potentially dangerous substances and provide people with information about the risks associated with their drugs.
Before the latest mortality figures were released, the Scottish government announced that a new drug-checking service would open in Glasgow early the following month at the city’s safer drug consumption facility.
The service will allow people to submit drugs for rapid testing while also providing harm-reduction information and advice based on the substances identified.
Similar drug-checking services have been approved for Aberdeen and Dundee, while a fourth service is expected to be established in Edinburgh.
Drug-checking is intended to provide an additional opportunity to identify unexpected or particularly hazardous substances within the illicit supply. This is especially relevant as synthetic opioids such as nitazenes become more prevalent and potentially appear in drugs that users may not realize contain them.
Scotland’s latest drug-death figures illustrate the continuing scale of the country’s drug crisis while highlighting how quickly the risks can change as new synthetic opioids enter the illicit market. With more than 1,100 deaths recorded in 2025 and nitazene involvement increasing sharply, health officials, treatment providers, and harm-reduction organizations face continued pressure to expand access to care and develop new strategies for reducing preventable deaths.
