People who want to do drugs probably will. I was one of them, I smoked weed. For three years I had a lot of fun, and then the nightmare started. I quite the drugs but it was too late and I was taken into mental hospital for three months, and had to quit my study. For one year I lay on the couch waching tv at my parents' house. Then I did some community work, and after 4 years I was totally the old me and started studying again. Of the many weed users I was one of the unlucky, but it could happen to you. Don't do drugs.
