Ketamine is a hell of a drug.
It depends on who you are. K came out as a drug in the club and rave scene in the '90's, which I was a part of.
Let me tell you, when my buddies and I would do K, listening to music, we'd come out of a K-hole feeling so peaceful and good and positive about the experience, and hopeful. The literal opposite of Musk. I think just blaming drugs is a cop out on the level of stupid as the war on drugs campaign.
It's who does them and under what circumstance. Elon has shown well before he was known for doing drugs that he was a shitty person. It's not the K, it's Musk has no soul.
