And start treating nicotine like heroin.
I believe cigarettes and other tobacco products should be unlawful. If one wants to grow and dry their own tobacco to smoke, I am okay with that. But, productizing addiction of known deleterious substances should be illegal.
I am not disputing that cigarettes are indeed addictive, overwhelming evidence suggests that they are, but cigars in my experience are not and I would guess pipe smokers would also fall into the same category.
