The emergence of an LSD-like drug has been linked to several medical emergencies among Loudoun County teens in the last several weeks, according to the county sheriff’s office.

Authorities believe the drug responsible is 25i, commonly referred to as “LSD,” “smiles” or “N-bomb,” according to the sheriff’s office. The drug mimics the appearance of LSD and has been found soaked on small squares of blotter paper, making it easier to distribute, authorities said. It can also be ingested in powder form or injected.

In one recent case, Loudoun sheriff’s deputies responded April 14 to a Lansdowne residence where three teens were acting disorderly. One girl was found yelling incoherently, and she kicked the deputies as they tried to assist her, according to the sheriff’s office. Two other girls found inside the home were also behaving erratically, authorities said.

The three teens were taken to a local hospital, and one was then taken to Inova Fairfax Hospital for further treatment. All have since been treated and released, according to the sheriff’s office.

“25i can be dangerous, even at small dosages,” said Loudoun County Sheriff Mike Chapman in a prepared statement. “This drug can cause violent behavior, disorientation, seizures and death.”

The drug 25I-NBOMe (25i) was classified as a Schedule I controlled substance in 2013, authorities said.
