MJ does lead to reduced testosterone; that's about the worst thing you can say about it. Medically speaking, it is THE safest psychoactive substance on Earth. Frankly, it is THE safest substance on Earth - period. Aspirin causes hundreds of deaths each year and every other drug known to man has the potential to kill a human - with one exception, that being marijuana, the DEA even admits that and wanted to have it declassified as a class II "drug". Just a little Googling and you'll find the real truth about pot; it is a very powerful pain killer, anti-anxiety "drug", cancer fighter, the only known alzheimers disease fighter, clears up glaucoma, appetite stimulant, anti emitic, and many other things they have not discovered yet. It's not really a drug in the classic sense. They have recently discovered canabinol receptors in the brain! There are special receptors in the brain perfectly matched to the THC in marijuana that causes the wonderful feelings we have while high. So it's not like we are taking a big dose of drugs to get high; it's more of our brain being stimulated by the THC. Just order some cialis online and give him half a hit of that before toking up; he'll be the man of steel in an hour.
