Statistics Netherlands (CBS) and Trimbos, the Dutch Institute for Mental Health, have reported a sharp rise in drug-related deaths in the Netherlands over the past ten years. According to the latest figures from the National Drug Monitor, 378 people aged 15 and older died in 2024 as a direct result of drug use. In 2014, that number stood at 123.
The data concern only deaths directly attributed to drug use, such as overdoses. Cases in which drug use may have contributed indirectly – for example through accidents, infections from contaminated needles, or long-term health complications – are not included.
Opioids a major factor
The increase is largely linked to opioids and a category described as ‘other, unspecified drugs’. Opioids include substances such as heroin and methadone, as well as prescription painkillers like oxycodone, morphine and fentanyl. These drugs are known for their strong pain-relieving effects and high potential for dependence.
In 2014, 40 deaths were attributed to opioids. By 2024, that figure had risen to 161 per year on average since 2020 – more than a fourfold increase over the decade. While deaths involving heroin or methadone have declined, fatalities linked to prescription painkillers have nearly doubled since 2015.
Researchers note that in roughly one in three opioid-related deaths, the case was classified as suicide – a higher proportion than for other types of drugs.
Rise in ‘unspecified’ and designer drugs
A significant increase has also been recorded in the category of ‘unspecified drugs’, which rose from 45 deaths in 2014 to 135 in 2024. This group includes so-called designer drugs: synthetic substances with slightly altered chemical structures designed to mimic the effects of established drugs while sometimes remaining outside existing drug laws.
These substances may resemble variations of MDMA (ecstasy), amphetamines, LSD or certain sedatives. In some cases, the precise substance involved in a death is unknown, or multiple drugs were taken simultaneously.
Deaths involving cocaine have also more than doubled, from 24 in 2014 to 61 in 2024. By contrast, fatalities linked to stimulants such as amphetamines and MDMA remain comparatively low, rising only slightly from 14 to 19 over the same period.
How are drug deaths determined?
Although the figures show a clear upward trend, experts caution that determining whether someone has died from drugs is not always straightforward. When a person dies, a physician first assesses whether the death appears natural. If there is doubt, a forensic doctor may be called in. Practices vary by region. In some areas, toxicological testing of blood or urine is standard procedure; in others, additional testing is carried out only when drug use is strongly suspected.
Even when substances are detected, establishing causation can be complex. Individuals differ in tolerance levels, and drugs are often combined with alcohol or medication. A concentration that is fatal for one person may not be for another. Moreover, the rapid emergence of new synthetic drugs presents challenges for laboratories, which can only test for substances that are already included in their databases.
As a result, experts say the official figures likely represent a minimum estimate. Cases in which no toxicological testing is conducted, or where a substance is not identified, do not appear in the statistics.
For residents, expats and visitors alike, the data underline a broader public health trend: while the Netherlands is often associated internationally with its tolerant drug policies, the risks associated with both illicit and prescription drugs remain significant and, according to the latest figures, increasingly visible.
