yes weed is a gateway drug BUT it does not happen to everybody. i have this friend i known since kindergarten til now and has never tried anything else but weed. IMO it depends on the person and how easy he/she is to peer pressure. i admit at first i said i will never smoke weed and it took a long time for me to even try it and didnt do it again for another year.

but i know quite a few people who started out on weed and are on some other shit now.
