Microdosing has become fairly popular among people who want to enjoy a few of the benefits of psychedelic drugs like mushrooms and LSD without the hallucinogenic effects.
Essentially, a microdose is a small dose of your psychoactive drug of choice without the hallucinations. That means that your whole day won't be lost coming down from the trip. Instead, you get to enjoy a wide range of benefits, from productivity to the management of symptoms for conditions like depression and anxiety.
Because the effects of mushrooms are subjected to and due to limited available research, finding a dose that works best for you can be difficult. For microdoses, you should start with 0.1 grams of shrooms and then add 0.05 grams until you reach your sweet spot.
