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 carcinogen, marijuana contains cannabinoids and THC, which seem to discourage cancer. It is also impossible to die of an overdose. Put that in your pipe and smoke it.
