Smoke of marihuana is more toxic, than tobacco smoke
The group of Canadian scientists during a research has found out that tobacco smoke is not such toxic, as a smoke from marihuana smoking.
Marihuana smoke contains much more toxic cyanide and ammonia, than a cigarette with tobacco. Till now, scientists believed that tobacco smoking is more harmful not only for vessels, bronchus and lungs, but also causes strong addiction.
The earlier experiment has shown, that the youth who regularly smoked tobacco, failed to cope with physical and intellectual obligations, in comparison with marihuana smokers.
However the new research, during which experts studied the content of toxic substances in a smoke, has shown that a cloud from one cigarette with marihuana contains 20 % more ammonia and 3-5 times more cyanide, nitric oxide and aromatic amines, than a usual cigarette.
