Fact: Marijuana produces immediate, temporary changes in thoughts, perceptions, and information processing. The cognitive process most clearly affected by marijuana is short-term memory. In laboratory studies, subjects under the influence of marijuana have no trouble remembering things they learned previously. However, they display diminished capacity to learn and recall new information. This diminishment only lasts for the duration of the intoxication. There is no convincing evidence that heavy long-term marijuana use permanently impairs memory or other cognitive functions.
I would say that bold statement is the biggest problem with marijuana. Coupled with the (minimal) lung damage, this makes it into a dangerous drug. People do overstate the dangers of marijuana, but using it isn't without its risks.
And Sour Worms, there is a big difference between being unintelligent and being misinformed. Intelligence is about what you do with the information you have.
I also think all of these scientific studies need to be taken with a grain of salt (both pro- and anti-marifuana). Scientific evidence can be spun to support a huge number of half-truths.
