http://news.yahoo.com/no-long-term-lung-damage-marijuana-study-220625384.html So there is that. Another myth debunked by a 20 year study. Yet people still feel the need to deny marijuana to others who could use it to improve their quality of life. When I don't smoke daily, I can't work. I have epilepsy but my seizures are completely controlled by daily marijuana use. When I don't have access to it, I tend to have Petit Mal seizures at a rate of 2 or 3 an hour. Why would anyone want to deny such a drug from people who could benefit from it?
