The intensity of a magic mushroom trip is hard to measure. The amount of mushrooms you take and how potent they are both play a role in your psychedelic experience. Taking two grams of mushrooms instead of one gram won’t necessarily “double” how high you feel—your trip could be exponentially stronger.
The same is true with potency—taking a mushroom with twice the amount of psilocybin or psilocin may lead to an exponentially more intense trip.
Other important factors to keep in mind when taking mushrooms are set and setting, meaning your mindset and environment when tripping. Doing mushrooms with close friends out in nature will lead to a much different trip than doing them with strangers at a crowded party, regardless of potency or dosage.
