OTTAWA, Dec. 20 (UPI) -- A Canadian report says marijuana smoke contains more toxic compounds, including ammonia and hydrogen cyanide, than tobacco smoke.

Researchers, including David Moir of the Safe Environments Program in Kitchener, Ontario, determined ammonia levels were 20 times higher in marijuana smoke than in tobacco smoke, while hydrogen cyanide, nitric oxide and certain aromatic amines occurred at levels 3-5 times higher in the marijuana smoke, Science Daily said Tuesday.

The study was published in the Dec. 17 issue of American Chemical Society's journal Chemical Research in Toxicology.
