In this life the only thing a person really has are their thoughts and their ability to think... Taking drugs impairs and destroys that one thing that is truly yours... I don't understand the attraction of drugs.
The other thing is that I have heard it said that marijuana and alcohol are the same. In effect this may be true but in reality, if you want to make marijuana illegal then all you have to do is ban any plant that produces THC. On the other hand since almost any food can be made into alcohol the only way to make it illegal is to ban all foods... Not very practical. So with alcohol the best you can do is legalize it and manage it. Simply put, even though alcohol is a narcotic it is not the same as any other drug.
Lol, cannabis does not rob you of your ability to think. This is some Just Say No-era nonsense and your "I have heard it said that marijuana and alcohol are the same" reveals you speak from ignorance. Relaxing with some weed once in a while does not put you on the fast track to the Betty Ford Clinic, and the similarity to alcohol is that, if you choose to consume responsibly then it's just another way to enjoy your evening. OTOH, drinking to excess puts you at risk of alcohol poisoning and making various other decisions that may result in harm/death; consuming too much cannabis generally means the munchies or bed time.
