I would say that if you are SURE that you have pure LSD-25, then go for it. I don't think you will have any long term side effects.
I have taken stuff that did something to the nerves in my arms. I took some 'acid' and I felt it fuck with my arm. I still have the same sensation from time to time. That crappy 'acid' did something to my nerves.
But when I have gotten really good LSD, there were never any side effects. So just make sure you know what you're getting.
...yet another reason why the War on Drugs is a complete failure:
Eating bad shit fucked up the nerves in my arm. Now if LSD-25 was freely available, people wouldn't eat bad shit.
In other words, do shrooms.
