Apparently, he was diagnosed after he retired from boxing in 1981. However, some believe he knew he was sick long before that, and so did Don King, when he signed Ali to Fight Larry Holmes in 1980, but i don't know if that's true.

Heavy marijuana users is the phrase most often used for long-term smokers. There's no diagnoses for that, but research recently spoke of "shrunken structures inside the brain."
Caffeine, by a wide margin. Marijuana is addictive over long-term heavy use. Caffeine users can become addicted in a matter of a few weeks. (We know that we will get comments from people who do not want to believe marijuana is addictive. We have worked with recovering addicts for years, and can assure you from personal observation of many patients that THC, the active ingredient in marijuana, exhibits all of the characteristics of an addictive drug in heavy users.)
Abuse of any drug can cause problems. However, long term marijuana use does not cause cancer or heart disease, like cigarettes could.Psychologically, long term use of marijuana could bring out underlying mental illnesses (such as a depressed person getting more depressed).
Urine tests may detect marijuana 1-5 days after an occasional use, 1-3 weeks in regular users, and 4-6 weeks in multiple daily users.
No, there are no known side affects from marijuana. Its nothing like cigarette smoke. And no long term health problems have been proven orfound in scientific studies. Perfectly safe. But illegal.
No study has yet been completed on the comparison of lifespan between marijuana users and the general populace, nor on the effect that marijuana has. However, it is possible the benefits - pain relief and relaxation, stress relief - would balance out the negative effects - usual problems associated with smoking, problems caused by using psychoactive drugs in the long-term.
