Apologies for repeating myself from elsewhere in this thread, but the 'paranoid from the weed' effect is extremely well known among smokers. I feel the need to stress this, coming from someone who has had more experience with weed, both personally and from social circles, than probably most in this forum (even accounting for the California contingent).

Some can deal with it easily and are unaffected, many are eventually a bit debilitated by it, and for some it triggers major problems. No need to sweep this under the rug.
