One of the biggest arguments anti-marijuana warriors use is the “we don’t know enough about this stuff” ploy.
I’ve been guilty of saying that myself.
But the truth is there’s plenty of information available about marijuana’s effects, both medically and recreationally. We know its potential and its pitfalls. We also know how a population will deal with marijuana in an unregulated atmosphere. Think of the United States before pot was criminalized, back when it was part of the pharmacopoeia of its day.
