The health effects of marijuana

There is a wide range of seemingly contradictory research on marijuana coming out in recent years. Some says it hurts memory; others say it prevents Alzheimer's. Some suggests it treats depression; others that it precipitates psychosis. Depending on your source, you may be getting quite biased information. Medical marijuana advocates no doubt leaving out the bad and drug warriors leaving out the good. However, when data is mixed, one must necessarily err on the side of caution. For everything, marijuana is supposedly good for, there are other substances equally as good with none of the downside that comes with habitual use. As a result, any rational person would only indulge occasionally if at all.
