Truffles, often referred to as magic truffles, are the underground part of the mushroom and contain psilocybin, the same active ingredient found in magic mushrooms. However, the potency of truffles can differ from that of mushrooms. This variance means that users may need to adjust their dosages accordingly. For instance, a user might consume a certain amount of truffles expecting effects similar to those of a specific amount of mushrooms, but if the truffles are less potent, the experience may not meet their expectations. Conversely, if the truffles are more potent, the user may find themselves in a more intense psychedelic state than anticipated. It's always wise to calculate the possible amount of psilocybin in each practice.
