Legalization & legitimate manufacture/sale of all so-called illicit drugs is the only viable way to dry up the drug trade. Drug ABUSE is a health problem. Responsible, recreational drug use harms no one, as can be witnessed by the millions of people who drink alcohol (a recreational drug) safely & responsibly for the sole purpose of getting high. (Nobody really believes beer or scotch actually tastes good. It's the buzz they are after).
Removing criminal penalties decriminalizes millions of otherwise law-abiding citizens who have done nothing more that have an enjoyable experience.
When the tyrants criminalize the consumption of meat, will you be a criminal or a vegan?
