Weed in Lisboa.
What the law allows.
Portugal was the first country in the world to decriminalise the use of all drugs. This guide explains what that means for weed in Lisboa, weed in Lisbon and cannabis in Portugal — your rights, the real consequences, and where to find support.
Portuguese law, explained.
Portugal did not legalise drugs. It decriminalised personal use. The difference is enormous — and it is what makes the Portuguese model unique in the world.
Use was a crime
Using or possessing drugs for personal use was a criminal offence, punishable by prison. Prisons were full of users, not traffickers.
Decriminalisation of use
Consumption, acquisition and possession of drugs for personal use ceased to be a crime. They became an administrative offence — with no prison sentence.
Dissuasion Commissions
Anyone caught is referred to a Commission for the Dissuasion of Drug Addiction (CDT), made up of lawyers, doctors and social workers. The CDT can apply administrative sanctions or refer the person to treatment.
Supervised consumption rooms open
Portugal opens supervised consumption rooms in Lisbon, under medical supervision, to reduce overdoses and connect users with health services.
Use remains unlawful — but not criminal
Drug use is still prohibited. But the response is administrative and public-health based, not criminal. Trafficking and supply remain serious criminal offences.
What actually changes.
The difference between "crime" and "administrative offence" is not just a word — it is a total shift in how the state responds.
Criminal court, prison sentence, permanent criminal record.
Administrative commission, no criminal record, health-focused response.
Prison, criminal fine, record affecting employment and travel.
Administrative fine, licence suspension, or referral to treatment.
Criminal judge.
Multidisciplinary commission: lawyer, doctor, social worker.
Serious crime, prison sentence.
Serious crime, prison sentence. Unchanged.
