Prague has taken a significant step forward in cannabis policy. As of January 2026, a major reform of Czech criminal law has decriminalized personal possession and home cultivation of cannabis for adults . This makes the Czech Republic one of Europe’s most liberal countries for cannabis policy, joining Germany, Malta, and Luxembourg . However, the sale of THC-rich cannabis remains strictly prohibited .
This guide explains exactly what is now legal, what remains illegal, and the critical distinction that tourists must understand.
What’s Legal Starting January 2026
For adults over the age of 21, the new rules establish clear legal limits for personal use :
| Activity | Legal Limit | Beyond Legal Limit |
| Home possession | Up to 100g | 100-200g = misdemeanor; over 200g = criminal offense |
| Public possession | Up to 25g | 25-50g = misdemeanor; over 50g = criminal offense |
| Home cultivation | Up to 3 plants | 4-5 plants = misdemeanor; 6+ plants = criminal offense |
Possession of up to 25g in public is now officially “not an offense” according to the European Union Drugs Agency (EUDA) . The law removes the previous vague “quantity greater than small” threshold and replaces it with these specific, clear limits .
What Remains Absolutely Illegal
Despite these progressive changes, the sale and commercial distribution of THC cannabis remain illegal . The Belgian government’s travel advice explicitly states: “The sale of cannabis comprising THC (>1%) is not permitted” .
Key prohibitions to understand:
- Selling THC cannabis is a criminal offense under Section 283 of the Criminal Code, punishable by 1 to 5 years imprisonment (up to 18 years for large-scale operations)
- Giving or sharing cannabis with others is also illegal
- Import and export of cannabis across borders is a criminal offense
- The 1% THC limit for legal hemp remains in place—products exceeding this are considered illegal drugs
What This Means for Tourists
The decriminalization of possession applies to everyone in the Czech Republic, including tourists. However, you cannot buy THC cannabis legally anywhere in Prague .
If you are caught with quantities within the legal limits (up to 25g in public), you should not face prosecution. However, the shops around the city center selling CBD and alternative cannabinoids are not selling legal THC weed. They operate within the 1% THC limit or sell other cannabinoids like HHC (which is now increasingly restricted) .
The Sale of THC Is the Crime
This is the critical distinction: possession is decriminalized, but sale is criminalized. Anyone selling THC-rich cannabis in Prague is committing a criminal offense, and buyers are participating in an illegal transaction . Online sales of psychoactive substances are actively monitored by authorities, and even small-scale sales carry prison sentences .
Conclusion
In 2026, Prague offers one of Europe’s most liberal possession frameworks—you can legally possess up to 25g in public and grow up to 3 plants at home. However, the commercial sale of THC cannabis remains illegal, and the cannabis shops you see around the city are not selling what many tourists expect. Your safest option is to understand the distinction between possession and sale, and to avoid the unregulated market.
