You’re never going to be able to recreate the combination of factors it takes to get out of depression in a lab. She could have taken some ecstasy, gone to a rave, met someone and completely changed the trajectory of her life. Same with speed- become temporarily manic and do something completely different. Most heroin addicts die from an overdose, you’re underestimating how much an addict looks forward to their next fix, nothing else matters. I’ve seen this anecdotally many times though anecdotal experiences only hold so much weight. At the end of the day what did she have to lose if she was going to be euthanized anyways. People take drugs to deal with problems and this is a problem. Hell, give her a huge dose of ketamine and put her into a massive k hole, people with depression respond fantastically to that.

I would never give hallucinogens to a depressed person, that could be enough hell to break someone’s mind permanently.
