Not true, really. I used to buy into all that. I was raised as a D.A.R.E. kid and would eat up and regurgitate any anti-drug propaganda. MDMA puts holes in your brain! Weed will make you violent and lazy at the same time! LSD will make you psychotic! Shrooms are a poison! Heroin is only for hookers and deadbeats! It actually wasn't until I tried pot for the first time and realized that it was nothing like what I had been told and it was actually better than alcohol on my brain and body. After that I thought to myself "What else could they have been wrong about." Which led me to researching it for myself. So yeah, it is possible to turn around from all that propaganda, but I think it takes an open mind or a mind opening experience to start it off.
