LEWISTON — Police and drug agents searched Paris Adult Book Store on Thursday after receiving tips that bath-salts-like substances and other synthetic drugs were being sold at the Lisbon Street store.

Half a dozen agents, police officers and a detective went into the store at about 3 p.m. to execute a search warrant. By the end of the search, they had seized more than $10,000 worth of items that will be tested at a state lab.

Nobody was charged. Police described the investigation as ongoing.

Maine Drug Enforcement Agency Supervisor Matthew Cashman said police had received numerous tips over the past six months that people from several areas, including Oxford, Portland, Farmington and Skowhegan, had been buying synthetic hallucinogens at the Lisbon Street store.

A girl in Skowhegan was recently hospitalized after taking synthetic substances police say had been bought at Paris Adult Book Store.

While they searched Thursday afternoon, half a dozen customers walked up to the doors of the store, saw police inside, and got back into their cars.

Illegal synthetic drugs are often marketed as bath salts and given colorful names such as “Barely Legal,” “Meow, Meow” and “Zoom.” Users typically snort, smoke or eat the chemicals for an amphetamine-like high often accompanied by wild hallucinations.

In September, Maine lawmakers passed a bill to increase the penalties for selling or possessing the synthetic drugs typically found in the product sold as bath salts. The law recently went into effect.

Paris Adult Book Store is across Lisbon Street from the police station and is owned by Dan and Diane Beauchesne.
