BACKGROUND: Despite the Netherlands having one of the world's oldest medical cannabis programs, the majority of people who use cannabis for medicinal purposes continue to rely on non-prescribed sources. This study investigates patterns of use, motives for use, perceived effectiveness, and barriers to accessing prescribed cannabis among individuals self-medicating with non-prescribed cannabis.
METHODS: A cross-sectional online survey was conducted between January and April 2023, using convenience sampling primarily via social media. Participants (N = 1059) were adults (18 years or older) residing in the Netherlands who self-reported current use of non-prescribed cannabis-based products to manage physical or mental health symptoms.
RESULTS: Cannabis was used to manage a wide range of conditions, most commonly chronic pain, sleep disorders, depression, and ADHD/ADD, with three out of four participants reporting use for multiple conditions. Most participants obtained cannabis from coffeeshops, although one in four also reported home cultivation as a source. Participants typically smoked cannabis with tobacco, reported (near-)daily use for therapeutic purposes, and indicated a monthly expenditure of €100. The majority was not aware of the THC and CBD content of their products. Perceived effectiveness was rated as high, and more than half of those with a history of prescription medication use reported substituting cannabis for these medications. Only a minority of participants had ever used, or were currently using, prescribed cannabis. Commonly cited barriers included perceived lower quality, higher cost, and lower ease of access compared with non-prescribed cannabis.
CONCLUSIONS: The widespread use of non-prescribed cannabis for medicinal purposes in the Netherlands reflects both unmet health needs and barriers within the regulated medical cannabis system. Risky use practices - such as smoking cannabis with tobacco and using products without knowing their cannabinoid content - raise public health concerns. The findings highlight the need for harm reduction strategies and policies that better align medical cannabis regulation with patients' real-world behaviours and care needs.
