Joycelyn Elders, MD, former US Surgeon General, stated in a Dec. 14, 2002 editorial published in The Globe and Mail:

“Much of their [US drug-policy leaders] rhetoric about marijuana being a ‘gateway drug’ is simply wrong. After decades of looking, scientists still have no evidence that marijuana causes people to use harder drugs.

If there is any true ‘gateway drug,’ it’s tobacco.”
