I must say that I I started this thread because I enjoy the lively debate. I support legalization, but as a former biochemist/molecular biologist I have questions. Background: My research was directed toward developing a viral vector for gene therapy with the intent of treating lung cancer and cystic fibrosis.
I couldn't care less if it is a "drug." I wake up every morning to my upper - caffeine - and I wind down every night with my downer - alcohol. Just like alcohol, THC must be used responsibly, and I think that appropriate laws regarding driving and performing certain jobs should apply. Furthermore, laws concerning second hand smoke should also apply. As someone whose career depends upon passing very sensitive drug tests, I cannot sit in a restaurant next to a table of pot smokers.
In terms of health, it doesn't matter what you smoke, you are still taking a bunch of chemicals and particulate matter into the lungs and this is not healthy. In patients, it is true that the health benefits outweigh the health risks. Initial studies do suggest a link between cannabis smoking and cancer. Therefore, I personally believe that before we even go down that road, cannabis should be treated like tobacco for advertizing purposes. Just like tobacco, I don't want it to be advertized to children, including sports sponsorship, and the negative health effects need to be researched and the information made very public.

The lung cancer side of my research involved using Adeno-Associated Virus to carry the p53 gene into the cancer cells to replace the damaged genes. The linked article discusses the relation between benzyprene and the p53 gene. While I have been out of the field for 16 years, and I do not have the evidence to back up the following statement, I will make it anyway:
CANNABIS CAUSES LUNG CANCER. Automotive exhaust also causes lung cancer, but I drive my car every day, and I attend car races. The question that need to be answered are what is the incidence rate of cancer in relationship to exposure to cannabis smoke. I predict that the relationship does not bode well for for the stoners.
