Here is a list of interesting facts about marijuana smoking and tobacco smoking:
o Tobacco contains nicotine, and marijuana doesn't. Nicotine may harden the arteries and may be responsible for much of the heart disease caused by tobacco. New research has found that it may also cause a lot of the cancer in tobacco smokers and people who live or work where tobacco is smoked. This is because it breaks down into a cancer causing chemical called `N Nitrosamine' when it is burned (and maybe even while it is inside the body as well.)
o Marijuana contains THC. THC is a bronchial dilator, which means it works like a cough drop and opens up your lungs, which aids clearance of smoke and dirt. Nicotine does just the opposite; it makes your lungs bunch up and makes it harder to cough anything up.
o There are benefits from marijuana (besides bronchial dilation) that you don't get from tobacco. Mainly, marijuana makes you relax, which improves your health and well-being.
o Scientists do not really know what it is that causes malignant lung cancer in tobacco. Many think it may be a substance known as Lead 210. Of course, there are many other theories as to what does cause cancer, but if this is true, it is easy to see why NO CASE OF LUNG CANCER RESULTING FROM MARIJUANA USE ALONE HAS EVER BEEN DOCUMENTED, because tobacco contains much more of this substance than marijuana.
o Marijuana laws make it harder to use marijuana without damaging your body. Water-pipes are illegal in many states. Filtered cigarettes, vaporizers, and inhalers have to be mass produced, which is hard to arrange `underground.' People don't eat marijuana often because you need more to get as high that way, and it isn't cheap or easy to get (which is the reason why some people will stoop to smoking leaves.) This may sound funny to you -- but the more legal marijuana gets, the safer it is.
