I don't know about paranoia, but sometimes when I walk my dog in my complex at night, while high, I become super-alert at small noises & stuff. It's a pretty nice complex, so there's not a huge reason for me to be all alert... it might be the weed I suppose.

I usually smoke at home in my cozy place, watching movies or comedy central or something entertaining. I cannot smoke & go out in public much ('cept to the movies), because I am pretty noticable... one of those people who gets extremely squinty & stuff. It was funny in massage school, because everyone got high at lunch, but wouldn't let me smoke if we had to go back to class (too noticable, hehehe).

So I guess I just know my limitations & just do it at home or with good friends when we don't have to do anything 'cept chill & be happy.
