LMsA: He expresses profound regret that not everyone having mental health issues can experience this.
Many mental health issues are caused by (or result in) changes in brain chemistry. And those are usually treated with drugs that try to help get the brain chemistry closer to normal. Advocating that such people alter their brain chemistry with psychedelics sounds dangerous. Doing so after deciding to stop taking prescribed mood-controlling drugs sounds particularly stupid and irresponsible, even for him.
Someone mentioned Boogie2988 recently. I think a case can be made that Evans has been entering into that territory, and I wonder if this is where he decided to go all in. I don't think it will end any better.
