Lately, It seems whatever I say stirs up controversy, but here goes.No Medical test that I know of has ever established that Marijuana is harmful.Other than smoking is smoking, but most pot smokers don't smoke 20 joints a day. Its not good to substitute one addiction for the other, but as far as which is more damaging ? No contest drinking is worse hands down and cigarettes are worse than pot also , but many "clean and sober"people chain smoke. Don't get carried away ! When you feel better try sustained periods without smoking pot see if you can do it. Don't blow your whole paycheck on weed. I know many very successful productive people who use and don't abuse pot. Be honest with your self is it a treat a habit a problem ? Congratulations on quitting booze, your life will be better without it.
