Welcome to OCF. Although there are zero valid studies showing smoking marijuana causes cancer by itself, unlike tobacco, smoking anything at all is a big NO NO for any oral cancer patients. They should use a vaporizer or ingestion instead. Our tissues are just too traumatized for the damage that any smoking can do.
If your post means you are looking on harmful effects of MJ, the best misinformation and false statements can be gotten from the DEA which refuses to allow scientists to conduct studies to show the benefits that actually exist . Unfortunately, as the post you quoted states, the resistance to allowing studies is "mighty". That way all the logic impaired drug warriors can say with a straight face: there are no valid scientific studies showing Medical marijuana works so it must be bad. Luckily, many state legislators know cancer patients and know how helpful medical marijuana can be. As EricS once said to me about people who oppose medical marijuana laws:[quote] Why do all these people keep wanting to torture cancer patients?[/quote]
Here is a link I posted before from a judge who is a cancer patient and has seen the light of truth
New York Times: Medical MJ hope you have recovered from your cancer
