well there have been studies that have shown that smoking releases carcinogens that cause cancer however other studies show that caniboids actually can help fight cancer...to me you can find a study for anything.

Smoking anything in my opinion is unhealthy. The vaporizing is great because you are only getting the THC and there is no carcinogens released.

Yes you can get high from eating pot, cooking it releases more of the THC however you can get high from chewing it although it's not really effective
