1. Medical Marijuana Has Been Around For Thousands of Years
In Ancient China, the plant, known as Ma, was used for food, fuel, clothing, and medicine going back to 6,000 B.C. But the oldest existing reference to medical marijuana dates to 2737 B.C. when the Red Emperor Shen Nung is credited with writing The Herbal, a listing of medicinal properties of various herbs, including Ma, to alleviate rheumatism and gout pain. In 2 A.D. Hua T'o is recorded as having used Ma-yo (the female plant) and red wine as an anesthesia while he performed painful surgeries including organ grafts and loin incisions. Yeah, you'd probably want to be high for that (Source | Via)
2. Marijuana use causes cancer
Fact: It's true that marijuana smoke, like tobacco smoke, contains carcinogens. But even hardcore pot smokers typically consume much less pot than tobacco smokers do cigarettes, probably not enough to cause cancer. A 2006 UCLA study concluded that even heavy marijuana use does not lead to lung cancer. "We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use," said the study's lead author. "What we found instead was no association at all, and even a suggestion of some protective effect." This and other studies suggest that pot can actually inhibit the growth of cancerous tumors. Finally, what risks there are involve smoking, and there are other ways to consume marijuana.(Washington Post)
3. Marijuana is actually GOOD for your lungs!
That's right, a recent study of 5,000 pot smokers by UCSF and University of Alabama showed that those who only smoke a few joints a week actually had stronger lung capacity and external blowing force than non-users. A 2005 UCLA paper also shows that marijuana smoke might actually help to PREVENT lung cancer. Unlike tobacco, which contains nicotine and is a known carcinigen, marijuana contains cannibinoids and THC, which seem to discourage cancer. It is also impossible to die of an overdose. Put that in your pipe and smoke it
4. Using marijuana leads to crime and delinquency
Fact: The rate of pot use is higher among offenders than nonoffenders, but that definitely does not mean that pot causes criminal behavior. Another factor may be driving both results – or it could be that the causality goes the other way, and criminals are just more likely to use drugs. Furthermore, pot, unlike alcohol, doesn't generally unleash aggression, so it's much harder to link it to violent crime
5. Gender-bender
Smoking up could be a very different experience for men and women, according to a 2014 study in the journal Drug and Alcohol Dependence. In research on rats, Washington State University psychologist Rebecca Craft found that females were more sensitive to cannabis' painkilling qualities, but they were also more likely to develop a tolerance for the drug, which could contribute to negative side effects and dependence on marijuana.
The female rats' higher levels of the hormone estrogen seem to play a role in these sex-specific effects. Female rats are more sensitive to the effects of cannabis at ovulation, when estrogen levels are highest, Craft
6. Marijuana use leads to dependence or addiction
Fact: It's possible to become dependent on marijuana, but this only happens in a minority of the already relatively small category of heavy users. Research suggests that about nine percent of marijuana users became clinically dependent at some point, compared to 15 percent of cocaine users and 24 percent of heroin users.
