Earlier quoted context omitted.
LSD is not physically toxic the way alcohol can be when taken in excess. Furthermore, this is more of a matter of opinion but I strongly feel it doesn’t dull your senses / decision making / cognition the way alcohol does.
> LSD is not physically toxic the way alcohol can be when taken in excess. On the other hand it can result in permanent personality changes / dissociative identity disorder.
LSD does cause permanent personality changes. That's what makes it such a beautiful compound. For me, it permanently altered my openness to experience, made me more intuitively empathetic, and improved my communication skills (the last two are two sides of the same coin). As a result, I am more well-adjusted, better able to communicate, more in tune with people's unspoken emotions and better at dropping into that unique state of vulnerability that we often call love. *
Your mileage may vary.
* Actually, psilocybin mushrooms were my first psychedelic so I credit them with that more than LSD per se. LSD was like the icing on top, really.
