BOISE -- Boise Police have a strong warning for parents in the Treasure Valley. A synthetic drug, new to Boise, is proving to be especially dangerous. There have been six overdoses in just three months, and one of the teenagers nearly died.

Parents need to know that this is a new drug in town, said Sergeant Michael Harrington with Boise Police Narcotics Unit.

The drug is known as 25i or 25C, and Harrington says it's created in a powder form, but can be melted down to a liquid. He says BPD believes the drug is showing up in Boise as hits or tabs on blotter stamps. Users absorb the drug by placing the stamps on their tongues.

The drug is inexpensive and powerful, similar to LSD. Harrington says it causes hallucinations, aggressive behavior and seizures. However, because the strength of each dose of 25i is different, Harrington says its effects can vary greatly.

What scares us the most is we've had approximately six overdoses in the last three months, said Harrington. That is a pretty high frequency of overdoses to have, a couple of them pretty serious.

In October two 16-year-olds overdosed on 25C, a chemical closely related to 25i, also known as N-BOME. Both teens were hospitalized; one was placed in ICU after suffering a seizure and reportedly stopped breathing. Before that incident, BPD says it is aware of at least four other drug overdoses involving young adults reportedly taking 25i.

Boise Police are now investigating to learn more about 25i and its counterparts. They believe the designer drugs are responsible for several crimes in the city.

I know one person was walking on top of cars and stomping cars, that type of aggressive behavior, said Harrington. I know another person was just wandering around into people's houses, knocking on their doors, trespassing on their properties, just kind of lost, didn't really know what she was doing or what was going on.

Harrington says the best defense for parents is education. He also strongly encourages parents talk to their children about the dangers of this new drug.

Boise Police say anyone aware of the use or sale of 25i is urged to contact Crime Stoppers at 343-COPS (2677), or log onto, or text CRIMES or 274637, subject: Tip236.

Tips can also be made via the Crime Stoppers Facebook Page at A citizen can remain anonymous. A reward of up to $1,000 is offered by Crime Stoppers for information leading to the arrest of criminal suspects.
