Speaking to this point exactly; drugs do not meaningfully fund terrorism. In a person's locality, one can readily learn what their supply chains consist of, and who is the chemist/grower producing it. For one to assume flat out that all drugs somehow for some reason pass through a cartel shows lack of knowledge, or bad faith. Especially today in the booming drug market, one can very easily buy right from cannabis growers and right from chemists, or nearly directly. Cartel drugs are frankly poor quality absolute garbage.
