Students for Sensible Drug Policy (SSDP) has been one of the good organizations out there making a difference. I’ve been to a couple of their conferences and know a number of their members, and I’ve been faculty advisor of a college chapter as well. They fulfill an important need — reaching students at a time when they are seeking knowledge, answers, direction.
SSDP is undertaking a crowd funding campaign with Indiegogo. Worth checking out.
