I guess you don't know that Canada already uses marijuana in medical ways. Do not you think it would harm a lot of people? I do not think there is lot of corruption though. It would become a "TOO FREE" country, and people would go crazy. However, some state that the demand will decrease.
If Canada legalizes Marijuana, it will affect the society badly. The teenagers would start using it, and it would bring more problems to the development of the citizens. More immigrants would start coming into Canada in order to smoke. Even though it is a good treatment for some illnesses, it causes fatal problems to health.
No one ever found out the truth, but this is what has been discussed for years. Some say that there are things that we can't see, but feel;such as, wind, or love etc. some say that When someone asks for hapiness, Does God give it? No, he gives the opportunity to become happier. I guess it's all about personal choice, and intellegence of every individual. I do believe in God because I feel like I must, because it comes from my own relative history, and I can't reject it. I do believe because when there is no hope, it is what does not let me give up.
