You can buy seeds online and grow your own. If you do that just make sure you buy feminized seeds. That means the seeds are guaranteed female and it prevents you from having to pick out the females and destroy the males. The males will pollinate snd seed your females. You don’t want that. It’s only the female plants that create big buds. Over here every household can legally grow 4 plants. If you start the seedlings early, prune them, so you get more bud sites, you can grow enough to last quite a while.
The small leaves can be used to make canna tea which is a nice soothing drink, not a high you’d get in your twenties.
And yes cannabis can cause paranoia. If you have a paranoid personality, this might not be for you. It can make it worse. This definitely isn’t for everyone. Some people shouldn’t have it at all but everyone should be able to have a choice.
( in my opinion )
