It is common knowledge that smoking is a possible cause of cancer, especially lung, larynx and mouth cancers, and a major risk factor for developing such diseases as heart attack, stroke, emphysema, etc. But what kind of smoke has been actually proven to be harmful? You may be surprised to learn the answer – tobacco has been proven to be damaging to a human body, whereas cannabis has been proven to be not dangerous. These are scientific facts, and they have been recently proven by several independent studies. Some of the suspicions and fears that many people had had in mind regarding these substances finally had been confirmed by science.

Numerous studies were conducted worldwide and occurred in a different settings and time intervals. A large number of volunteers have been observed and tested over a period of five years in one of the experiments, and another one lasted for ten years. There are many more that are still on progress. Despite of the diversity of the research, the conclusion has been practically the same – long-term use of marijuana has nothing to do with developing cancer, such as melanoma, colorectal, lung, prostate, cervix, or breast cancer. As far as cancer patients are concerned, in some cases they are actually prescribed Marinol – a pure THC in a pill form (active ingredient of marijuana) to help deal with eating disorders, nausea and various other of the side effects of dealing with this horrible disease.

Population based case-studies had confirmed the negative influence of such substances as alcohol and tobacco, and now it has been officially confirmed that consuming marijuana does not have similar negative effects on human body as alcohol and tobacco do.
