As long as you're not in the middle of nowhere weed is easy to get and it's often pretty good (albeit not as much choice as people in legal areas would be used to I'm sure) but stuff like professionally made THC candy is gonna be pretty difficult to source. As for advice for picking up, it's probably fairly similar to places in the US and Canada back when it was illegal, you just gotta find the right places/people to ask. I've never done it before but apparently a fair few people deal here from Snapchat and Tinder now so I guess you could always give that a go lmao.
