I live in Ireland and I was listening to a radio show about the government planning on decriminalizing drug use. A caller brought up a point that it's no good decriminalizing if education about drugs isn't also taught in school as well.
My teenage nephew goes to high school in the U.S. and apparently gets several class on the different classes of drugs and their effects. Now, granted he does go to a private school but I never had any of that when I was younger. Why is this not common?
