I know that in Japan, China & Korea along with SEA including the Middle East, it’s definitely criminalized and you’ll get arrested for bringing in weed (they’re indifferent whether its for medicinal or recreational use) since they do not allow it on their turf. In some countries, that guarantees a death sentence as they have zero tolerance on allowing those substances. It’s not like let’s say Canada or Germany where weed is tolerated.
Travelers who are weed users aren’t stupid to travel internationally with cannabis as they’re aware the rules are different across borders. Then, if they crave for weed (but can’t consume that as it’s a crime in those countries) what’s the alternative? Over the counter pills, maybe? Other valid substitutes that may give off similar vibes. I’ve heard a case where an American couple had their weed confiscated in Australia, where it’s illegal.
FOAF was a rasta type from (iirc) Australia. Everything about him (clothes, dreadlocks, etc.) screamed “pot user”. He flew to some other country and of course customs immediately pulled him aside and asked him if he had brought in any pot or intended to use it during his visit. He said “not here, mate. Only at home.” which was exactly the right thing. If he had said he wasn’t a user they surely would have searched him to the skin. Instead they recognized mutual understanding and things were fine.
Anyway, yeah, as everyone says, just do without it. If that’s a problem, well, it’s a problem that has a name and you should work on fixing it.
