Cannabis smokers are exposed to more toxic chemicals in each puff than those who smoke only tobacco

Cannabis smoke more toxic than puffing tobacco

Extract from the Guardian:

"Cannabis smokers are exposed to more toxic chemicals in each puff than those who smoke only tobacco, scientists have found. Earlier research shows cannabis smokers are more prone to lung damage than cigarette smokers.

In tests, directly inhaled cannabis smoke contained 20 times more ammonia than cigarette smoke, five times more hydrogen cyanide and five times the concentration of nitrogen oxides, which affect circulation and the immune system."
