I tend to agree with this. The main thing this does is takes away the profit from criminal gangs. Of course, when people make drugs illegal they don’t realize they are making criminal gangs rich. But, that is the result. Instead, people are thinking of the tweakers and homeless all over the streets, or their loved one who OD’d. And, truthfully, there likely are certain drugs that can never be used responsibly (opioids, meth). For those, society needs to find a way to manage it. Maybe give away the drugs for free in certain supervised spaces. And, forcibly treat people who are high in public. 8 years in prison for anyone that gives drugs to a minor. But, legalize the drugs so murderers aren’t the ones manufacturing and selling them.

Why tax it? Treat it like anything else. High taxes just make people go back to the black market.
