CANNABIS RISKS TOO GREAT

Thank you Gary Christian (Letters, July 11). In the British Medical 
Journal (March 3, 2013) Professor John Henry wrote " cannabis is as 
dangerous as cigarette smoking - it may be even worse", adding users 
are up to six times more likely to develop schizophrenia. Dr William 
Oldfield wrote puffs by cannabis smokers " are two-thirds larger, 
they inhale a third more, and hold down the smoke four times longer . 
. . chemicals in cannabis smoke are retained in the body to a much 
higher degree, and cannabis today is 40 times stronger than that used 
in the 1960s".
