I live in Canada, so all forms of cannabis is legal. This includes CBD and HHC. I understand why some people get HHC and Delta-8, but since THC is legal in Canada I have no reason at all to get something that isn't good and more expensive.
I think CBD is kind of useless, it does nothing, it's not psychoactive it can just make you chill. And HHC is nice, but I believe it has a use only in countries where THC is illegal and HHC not.
smoked cbd once in prague and didnt even veel anyting, but in spain i went to a weed shop and bought a hcc joint for 17,- wich was pretty expensive for one joint, but when we got home and smoked it we pretty high.
I'm in the UK, and as of my last check, CBD is legal here as long as it contains less than 0.2% THC. HHC, on the other hand, is a bit of a gray area. It's not explicitly mentioned in UK drug laws, but its legality largely depends on its source and chemical composition. Always best to be cautious and do your research to ensure you're within the legal bounds.
