I am 70 and have seen A LOT through the decades, so let me give you so food for thought.
1) I have seen a person have "flashbacks" from taking LSD and jumping to his death.
2) My best friend ever, back in the summer of 1978, came into my hometown and his younger sister flagged me down. Then we went looking for her older brother, my great friend, and found him in the middle of the street, wide eyed, sweating, and 100% out of it. Took street drugs, too many and took different ones together. To ER, to save his life.
3) Seeing people who had lifelong damage to their minds and/or organs and having to be in a home looking out a picture window, drooling with a bib around their neck and no idea about anything, gone for good mentality.
Everyone does as they please, I am a firm believer in this, HOWEVER, they ALSO are responsible for the outcome.
All my life I have seen the paradox of: It is none of your business what I do! That is 100% correct. HOWEVER, it is also so interesting, that those same folks, when the hammer falls, excepts the person that they told to "buzz off", to wail around and feel so horrible for them, and it was all of THEIR doing!!??
I love helping and loving everyone, I just wish that some or a lot of folks THINK about the future, do not see with your eyes BUT with your brain. that the future after doing whatever might come back and BITE HARD!
I care about everyone, and it was always so darn sad to see someone with a fried-out brain sitting in a chair drooling all day.
