Interesting view. What I find problematic is equating drug use with being "high." Sure, you can use enough of a drug that it impairs you, but you can also use less than that.
Some may refer to this as "microdosing" but I think this gets it backwards. If anything, drugs are useful tools that can also be "macrodosed" by those wishing to experience extreme effects.
I would like to live in a world where all drugs are legal and people can use them to enrich their lives, not just escape from them.
