What the hell, the chemicals in acid are totally gone from your system in under 30 hours..

Acid does not get stored in your spinal fluid.

Flashbacks are simply memories of a trip, which basically put you back in the mind set that you are tripping.
Brokedown Palace Reviewed by Brokedown Palace on . 3 questions, Acid Flashbacks? Shrooms? I am curious, and asking people I know and stuff can't get the same answers. 1.) What exactly are Acid Flashbacks? 2.) Is it possible to have Shroom Flashbacks (someone's uncle told me it was but he never had them) ...and what exactly does shrooms do to you to give you the effects you get? I checked Erowid but I must not have read it right or looked at the right place because I don't understand. Rating: 5
