Are you sure about that?

Some results of marijuana research are now coming in, and they're showing that it's not necessarily the benign drug that its advocates have claimed. It can reduce brain function and lower IQ. Especially for young users, it can apparently cause some significant damage.
"New research shows teenagers who smoke marijuana are not only affecting themselves, but possibly children they may have years down the road. Dr. Yasmin Hurd, with Mount Sinai Hospital in New York, is an expert on the effects of marijuana on the brain conducts studies that mimic human response on mice. She gave adolescent rats the equivalent of eight joints in a month. It was enough to make permanent changes in their brains that were passed on to their offspring. When those offspring grew up, many showed compulsive behavior and a strong appetite for heroin. 'Itís not that marijuana changes your DNA sequence, but we know that it changes, potentially, how your DNA is marked that changes how the genes are expressed in the brain. But, we definitely see clear brain differences in these adultsí offspring,' says Dr. Hurd."

Here's an article on new Northwestern research that shows that teens who are heavy pot users have abnormal changes in their brain structures related to working memory (working memory impacts ability to learn and perform). The problems were observed a couple of years after they stopped smoking the drug, while in their early 20's. The research also showed a link between chronic use of marijuana and the development of schizophrenia. Read more:
A poor working memory predicts poor academic performance and everyday functioning.
The brain abnormalities and memory problems were observed during the individualsí early twenties, two years after they stopped smoking marijuana, which could indicate the long-term effects of chronic use. Memory-related structures in their brains appeared to shrink and collapse inward, possibly reflecting a decrease in neurons.
The study also shows the marijuana-related brain abnormalities are correlated with a poor working memory performance and look similar to schizophrenia-related brain abnormalities. Over the past decade, Northwestern scientists, along with scientists at other institutions, have shown that changes in brain structure may lead to changes in the way the brain functions.

"An extensive four-decade [URL="http://www.pnas.org/content/early/2012/08/22/1206820109"]study published in 2012 by the National Academy of Sciences[/URL] showed marijuana can lower the IQ of young teenagers and may cause permanent mental impairment. The research, which followed subjects from 1972 to the present, found that persistent users of marijuana demonstrated 'neuropsychological decline from childhood to midlife.'"

The legalization aspect is a whole 'nother argument, and I respect your opinion on that. But to say that marijuana is clearly less dangerous than alcohol and tobacco? I'd say the jury is still out on that, especially in regard to young users.
