Despite what you may have heard, drugs, without exception, are illegal in Latvia. If someone offers you any type of drug, whether it’s weed, ecstasy or coke, you aren’t allowed to buy it and you’re definitely not permitted to carry it, even in small amounts for personal use. If you buy pot off of a stranger in Riga there’s a good chance you’ll get a bag of oregano or locally grown hemp that has a THC level barely above zero which would give you about the same buzz as you’d get from smoking dried parsley. You can purchase hemp butter at the Central Market legally, but it’s just something to spread on toast and definitely won’t get you high. If you’re looking to get inebriated, stick to Latvian beer and spirits.
