grams of dried cubensis mushrooms
= LSD dosage: X micrograms
LSD to Shrooms Dosage Conversion
micrograms of LSD
= Shrooms dosage: X grams of dried cubensis magic (psilocybin) mushrooms
e.g. 100 micrograms of LSD * 0.024 = 2.4 (grams of dried shrooms)
This is a rough approximation for many reasons, including that mushroom potency can be quite varied.
