If its acid then it won;t take an extra long time to kick in. You probably got one of the DOx. Thats the only other drug I know of that will have any effect at such a small dose. DOx is very bitter so it will feel like its burning your mouth like you said.
i think her cheif concern was asking if there was going to be any permanent physical damage to her actual body. in regards to that......no. the only danger with lsd is stricly mental.
I have taken 1 hit of a batch and then taken 2 and have a very different experience regarding strength, but it was 10x more beautiful and intricate. take it one step at a time, be in a positive environment andbe surrounded by people you trust and care about. if the set and setting are right, you will have an experience unlike any other
different batches of lsd dont have different qualities. the only difference is how potant the hits are. Like the guy above me said, the only real difference in effects would be if it was a different chemical, like the DOx compounds, which you can tell by taste. there is no such thing as bad acid or good acid, just how potant the doses are
