Hashish has been illegal since 1973, but it’s still readily available in Nepal. Thamel is full of shifty, whispering dealers. In practice, Nepali police aren’t very interested in people with a small amount of marijuana on them (they’re more focused on smuggling), but the technical penalty for drug possession is around five years in prison, so potential smokers should keep the less-than-salubrious condition of Nepali jails firmly in mind. Don’t try taking any out of the country, either – travellers have been arrested at the airport on departure.
If you get caught smuggling something serious – drugs or gold – the chances are you’ll end up in jail, without trial, and will remain there until someone pays for you to get out. Jail conditions in Nepal are reportedly horrific. Bribery is sometimes used to avoid jail. This is illegal and can land the perpetrator in deeper strife. Deniability that a bribe was offered – where the accused believed it was a legitimate fee – is the only defence.
Killing a cow is illegal in Nepal and carries a punishment of two years in prison.
