Purity - Is the acid legit?

[augentier]

Toonces did a quick scan over this page to see if it's been asked, didn't see anything, so point her in the right direction if this has been discussed..

Toonces is getting her paws on a few hits of acid this weekend..she has never tried it, she asked the person who is getting it how he knows it's real, and he said he has gone thru the guy before and "it's good" .. doesn't tell Toonces much but ok.

How can one tell if what she's taking is really acid? Hers is coming from an area where it is popular, and pretty much the only city in the state that is known to have it. Are there any specific feelings/effects that are exclusive to acid ?
