As far as amotivational goes..no bro. This information is credible.

It does not appear as though the amotivational syndrome is all that common among marijuana smokers. In one survey[2] a sample of almost 2000 college students was studied. There was no difference in grade point average and achievement between marijuana users and nonusers, but the users had more difficulty deciding on career goals, and a smaller number were seeking advanced professional degrees. On the other hand, other studies have shown lower school averages and higher dropout rates among users than nonusers. In any case these differences are not great. If there is such a thing as amotivational syndrome, its affects appear to be restricted to a few individuals, probably the small percentage who become heavy users.
Markass Reviewed by Markass on . Amotivational Syndrome, Low Sperm count. What I want to know (mostly from the older heads with more life experience) how do you think marijuana ACTUALLY affects people as far as being a "burnout"/amotivational syndrome and also about the low sperm count thing. I did a little research but it's almost all bullshit. Either it's whacked out hippy bullshit like "weed can cure any ailment" or whacked out right wing shit that says weed is 5 times more deadly than cigarettes and it makes your balls shrivel up and steals your soul.
