We know that alcohol and tobacco use, especially tobacco, are modifiable factors, but is it scientifically irresponsible to lump meth, cocaine, opiates together with marijuana? Is it an honest medical evaluation metric or is it pushed by an anti-weed government funding protocol. And please, where is the breakdown between those using weed, meth, opiates and coke. I’ll be willing to bet its almost nil for Maryjane. Weed is the only drug here which has no deadly dose. Weed is the only drug here that has NEVER caused an overdose. Ever. Please tell these researchers to stop beating up on the naturally produced Maui Wowie and concentrate on the man-made chemical poisons. Then and only then will we advance in terms of human health.
