PHILADELPHIA (WWTI) — Officials in Philadelphia say that a dangerous drug destined for the Hudson Valley was seized last week at the border. U.S. Customs and Border Protection (CBP) officers said that on January 20, they seized two shipments of dimethyltryptamine (DMT).

“Unscrupulous international vendors continue to peddle their illicit and dangerous products to American consumers,” warned CBP’s Port of Philadelphia Area Director Joseph Martella in a press release.

Authorities say DMT is considered an LSD-like hallucinogenic. It reportedly arrived in express delivery parcels from the Netherlands and was bound for Dutchess County. The naturally occurring substance is found in many species of South American plants, including mimosa tenuiflora, but has no approved medical use in the U.S.

The parcel with the hallucinogenic arrived on January 19. Upon an initial inspection, CBP officers said they discovered 57 pounds of tree bark pieces. Those pieces tested positive for DMT, a schedule I controlled substance. According to CBP, this drug is used for psychedelic and hallucinogenic effects and was popular in the 1960s.

The second shipment that officers inspected was destined for Chicago and was labeled as samples of butanediol, a solvent used to strip floors and thin paint. But upon examination, CBP officers said they discovered 10 bottles of clear liquid packaged as a cleaning solution.

That liquid later was identified as gamma butyrolactone—GBL, a DEA Schedule 1 controlled substance. According to the DEA, GBL is a highly addictive central nervous system depressant that poses potentially severe health consequences. Law enforcement reportedly classifies GBL as a “date-rape” drug precursor.
