Anything you breathe into your lungs that is not Oxygen, Nitrogen or Carbon is a carcinogen. Period. THC is what is called a secondary metabolite. So is nicotine. Secondary metabolites are things plants produce that are intended to be poisonous and are to a lot of animals - but not humans. A lot of people like to think that they smoke weed and, since its "natural", it wont hurt them but it causes the same thing as smoking natural tobacco.

I'm a cigarette smoker and have cut down and don't smoke regular cigarettes now, I roll my own that is grown and sold by a tobacconist here in town. It goes from having about 23 carcinogens to having 2.

The thing is - EVERYTHING causes cancer. And nobody can agree on anything. We all drank water out of Nalgenes thinking this is better for the environment because we are wasting plastic bottles etc... but those have BPA.....which causes cancer.

A study was recently released that states coffee can prevent certain types of cancer. But its addictive. Tomatoes can prevent certain types of cancer but can also cause horrible acid reflux and be really painful. Fruits like bananas and kiwis are good for you but are from a latex-based tree which can cause an allergy to latex.

My point being - everything has good parts and bad parts. Anything in excess is bad. Pot has been medically shown to help with a lot of things. Each individual needs to decide whether the bad things are worth it for the good. Right now, my smoking tobacco - lung problems outweigh the possibility of me going postal on someone lol. So anytime my parents tell me that its bad for me I say "would you rather me kill people? Cause you take away my nicotine and it will happen" lol

And I think that saying that all meth heads have smoked pot is a slippery slope. You can't say that pot is a gateway drug because hardcore drug users have all smoked it. Those people have probably done everything under the sun. I know many more people that smoke pot without ever moving on to anything else than people who use it and suddenly go "oh my....crack would be good!" It's just not plausible.

Someone should really go look up the history of hemp and weed and why it was originally outlawed in the first place. Hemp proves to be useful for everything timber is, and for much cheaper. The timber industry was in danger of loosing their business because of this crop that could take over for everything timber did. So a lot of money was put into campaigning for how awful it was (Hence the movie Reefer Madness).

And no thats not a conspiracy - my bf has a masters in forestry and confirmed this after I researched it and has done work in the timber industry himself.
