Microdosing is described as taking an imperceptible dose of an illegal psychedelic drug, typically LSD, MDMA or Psilocybin, more commonly known as magic mushrooms. It's a fraction – roughly a tenth -- of a full hallucinogenic dose that would cause a high.

"It's just been a constant upward trend, constantly on the rise," said a drug dealer who spoke with News 4 New York's I-Team on the condition of anonymity. 

The dealer creates "microdoses" by taking psilocybin or "magic" mushrooms, grinding them to a powder and pressing them into pills that are a fraction of a full hallucinogenic dose. He said that it's a growing group of people turning to street drugs and that they are looking for anything but a high.

"They don't take it to get high, they take it to get effective," he said. 

The dealer refused to say exactly how much money he has made capitalizing on this trend but said his client base has grown to about 100 people in the metro area.
