Operation Web Tryp

Operation Web Tryp was a United States Drug Enforcement Administration operation that ended on July 21, 2004 with the arrests of 10 persons. Its purpose was to investigate web sites suspected of distribution of unscheduled, unregulated phenethylamines of questionable legality. This trade in "grey market" drugs, which were not explicitly illegal but potentially prosecutable as drug analogs, became known as the "research chemical" trade; a euphemism for the fact that the chemicals were being sold for human consumption rather than industrial or academic research.
