I use marijuana occasionally and I must say that it is good. I particularly like the taste and smell. It is unique to all the other drugs plus it is cheap. It is stronger than most cigarettes and not as addictive. My friend usually has chest problems and can not be around smoke but he can smoke marijuana comfortably without any problems. I also hear that it is used in hospitals to reduce anxiety among some patients. I think it is popular due to its calming effect you will never get in any other drug.
