They found that blood flow improved in people who smoked up to 70 marijuana cigarettes a week -- people they defined as moderate users -- after a month of avoiding cannabis.
Heavy users, who smoked up to 350 joints a week, saw no change in blood flow even after a month, the researchers said.
70 doobies a week!?! That's like 10 a day. I'd say that anybody that has this sort of dependancy on ANYTHING is going to suffer side effects.....350 a week?!? That's 50 joints a day. I'd say that if someone is smoking that many a day chances are they've got a few more seriios medical concerns...cause that is beyond cronic....
