yo dude
I used to get crazy paranoid when I first started smoking, especially about people of any kind of authority like, hiding in places, waiting to jump out. I would think the police were hiding under beds and such. Looking back, it was really hilarious, but I can honestly say that weed does that maybe the first two or three times, mainly because it's vibrating neurons in your brain. The better the trip (and hash is a killer, especially for a first-timer) the more vibration of your intuition. So like... give your brain a few attempts to get used to that mind jacuzzi before writing it off, and if it still is crazy frightening, then fortunately there is not only not a violation of law for not using it, there's apparently a law not to! So you're in the green.
Bottom-line: I was once paranoid when high, and now instead get high and write messageboard posts.
