When I smoked with my family, I would feel so   16  and good that nothing else in the world seemed so   17 . I thought that smoking weed (烟草) was okay since many of my family members and people at my school smoked.  18  ever happened to them.   19  I started smoking weed a lot more during lunch and after school. I never thought   20  of it. At that time I just wanted to smoke. Then I began to   21 in school. I would   22  classes, come home late and spend all my money. I would spend   23  8 to 18 dollars a day. I never thought   24  that marijuana (大麻) had a bad effect on those things. Maybe my coming to class high (神智恍惚) was the reason why I was failing or coming home late. As I continued to smoke marijuana, I began to notice that I would always have the strong desire to smoke and that I would get   25  cigarettes if I smoked those, but I don’t.   26  I have learned more about marijuana, I have   27  the amount of marijuana that I use. I don’t want marijuana to be the most important in my life. I’m not smoking every day, and not spending as much money. Since I have   28  on my habit, I am   29  more money. I’m ready to go back to school and do good, so that I can make myself  50 . Everyone is always saying how weed   31  your mind and how it solves problems. I think it only brings more   32 . Marijuana is not good for your body or your brain. I’m not trying to tell you not to smoke, I’m just letting you know that marijuana can be   33  to your health, and   34  it may cause some long term negative (负面的) effects. Help yourself now, before it is too late. I don’t want to lecture anyone, just   35  my experience with you.
