why is it that some ppl get really paraniod when they smoke weed? I have experienced it a few times and its not fun.
usually because you're paranoid to begin with. most drugs amplify what you are feeling before it hits you. so if you go into it, all worried and paranoid....chances are, that's how the high will be.
Weed takes down that barrier that holds back those feelings and thoughts from the subconscious. Some people are more aware of the activities of the brain where others are oblivious.
