One of D.C.’s most privileged neighborhoods seems to be a good place to find DIY druggies. First, Georgetown journalist Howard Arenstein decides to grow giant pot plants in his backyard, now a clandestine dimethyltryptamine (DMT) lab shows up in a dorm at well-heeled Georgetown University.

But the two GU freshmen and campus visitor who were arrested Saturday for setting up a DMT lab in a dorm may have also had something a little lamer than a mind-blowing hallucinogen on hand: Fake pot.

According to a police source, though Charles Smith, John Romano, and campus visitor John Perrone were arrested in connection with DMT, what cops found along with chemicals like acetone and naphtha were several ounces of K2, a synthetic cannabinoid.

Legal for now, K2 is basically an herb sprayed with a chemical that mimics the effect of all-time-funnest chemical THC, which is found in marijuana. DMT and marijuana are sometimes mixed.

Originally, rumors flew that the secret lab was meant to produce meth. That might have been because some of the chemicals discovered could be used to manufacture the notorious drug. But that was before one of the three arrested admitted to cops that the lab, some of the parts of which were kept hidden in a suitcase, was meant to produce DMT.

The lab was discovered when campus police got a tip that drugs were being sold from room 926 in Harbin Hall. Besides chemicals, dry ice, mason jars,  and what might be DMT, they found about $1,300 in an envelope, according to the source. The source adds that Perrone, whose car yielded more evidence, is suspected of being the chemical mastermind behind the operation. (Which is to say, Georgetown’s chemistry department may need to step it up.)

The drug case has been transferred to federal court. That essentially implies that Smith and Perrone (prosecutors aren’t pursuing a case against Romano) are in serious trouble, and are unlikely to get a mere slap on the wrist.

If it turns out GU had its very own drug kingpins, maybe that has something to do with our current economic slump—the school is ranked the 15th most expensive in the country.
