I have used shrooms many many times at varying doses. The doses that I'm referring to as to the computer glitches is 4-5 grams. These are of course full potency. I have encountered shrooms that are weak around 1/4 to 1/2 of full potency for whatever reason. My GF tried some in the Amazon recently that were so weak that people were eating handfuls to very mild effects. Naturally harvested shrooms are often weak and so many people don't handle/process them properly. Unfortunately, I have found that the only way to insure consistently potent shrooms is to know the grower or grow them your self.

One other recommendation that I would offer is to either make a tea or run an extraction. Eating raw or dried shrooms is usually fine, but they do contain mycotoxins and can easily pull toxins from their environment. I have had a few experiences where the trip gets a bit nasty from stuff in the shrooms, but never experienced this from making tea as all oil soluble chemicals stay in the fibers. Eating raw shrooms grown on food media is perfectly safe given that there is ZERO mold but sometimes I can feel a little funk on higher doses. For these reasons, I almost always make tea or extract. The other advantage of tea is that it hits quicker and harder but it is also over quicker (10-20%).
