I agree that many people are born stupid. However the long term effects of marijuna are well documented. Google "THC brain fat" and pick a site at random from the dozens that come up:

"The chemicals in marijuana are fat soluble. This means that when you smoke pot, the chemicals are stored in the fatty tissues of your body, especially in your brain's complex and fragile fat cells. The THC in one joint remains in your body long after you smoke it. After 72 hours, only half of the THC leaves the body and it takes at least 3 weeks for it to completely disappear. If you continue smoking pot during that period, it will accumulate in your brain cells. This can result in long and short-term memory loss, reduction of motivation, and impairment of even normal learning functions."

This is what I observed with many of my classmates at U.C. They pissed away their university education. THC is a particularly insidious drug because like DDT it is an accumulative poison. Also since it degrades memory, the idiots taking THC can't tell that they're slowly turning in burnouts.
