　　When I smoked with my family, I would feel so ?26? ?and good that nothing else in the world seemed so ?27? . I thought that smoking weed (烟草) was okay since many of my family members and people at my school smoked. ??28 ?ever happened to them. ??29? ?I started smoking weed a lot more during lunch and after school. I never thought ??30 ?of it. At that time I just wanted to smoke. Then I began to ?31? in school. I would ?32 ?classes, come home late and spend all my money. I would spend ??33 ?8 to 18 dollars a day. I never thought ??34? ?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 ??35? ?cigarettes if I smoked those, but I don’t. ??36? ?I have learned more about marijuana, I have ?37? ?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 ??38 ?on my habit, I am ??39? ?more money. I’m ready to go back to school and do good, so that I can make myself? 40? . Everyone is always saying how weed ?41? ?your mind and how it solves problems. I think it only brings more ??42 . 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 ??43? ?to your health, and ??44? ?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 45? ?my experience with you.
