Lots of people have done acid since the 60s. Most people who did acid did not barricade themselves in their houses with guns threatening self-harm. Kinda like how alcohol doesn’t make you into an a*hole, it just brings it out if you already were one.
Don't be dishonest and disingenuous.
If a person chooses to take such substances, that is one thing. If such substances are slipped in to one's drink/food, WHOLE different story.
Not saying this is what happened here, but I sure as hell will not rule it out because it does in fact happen.
