Same here. Weed freaks me the fuck out. Hate it.
Weed as a drug has a biphasic response pattern, along with reverse tolerance.
Also, it's very strain specific dude.
Biphasic means that a low dose of THC/CBD will increase serotonin improving mood, anxiety etc, high doses drop it dramatically, you then get to see what it's like to live with OCD and freak out. The problem is that until you get a good tolerance the line between good and bad is razor thin and it's all to easy to get paranoid.
I am high right now.
