Dude, John Walters is a genius, don't you realize? He alone knows the crime-generating effects of the evil Marihuana. Do not use it. It's illegal, so don't do it! That's why you shouldn't use it, because it's illegal, and it will kill you eventually. Tobacco won't though, and nor will alcohol even have a chance. You cannot compare alcohol to the evil Marihuana, because alcohol only kills 150,000 people per year. Plus, Marihuana is illegal. Do you really want to support terrorism by using Marihuana? Next time think before you put the Marihuana poison in your body - think about the thousands of people that could die because of YOU!
