Just make sure the batmans don't look like these ones.
ECSTASY MIMIC TABLETS (ACTUALLY CONTAINING N-BENZYL-
PIPERAZINE, 1,3-TRIFLUOROMETHYLPHENYLPIPERAZINE,
1,4-DIBENZYLPIPERAZINE, AND CAFFEINE) IN BOISE, IDAHO
The Idaho State Police Forensics Laboratory in Meridian recently received four submissions of six types of tablets, suspected Ecstasy (see Photos 2 - 7). The tablets were acquired or seized in Boise by the Boise Area Narcotics Drug Interdiction Taskforce. The first two submissions (totalling 25 yellow Bart Simpsons and 25 blue “Autobot” Transformers) were acquired during undercover purchases. The third submission (25 each of green tablets with an Infiniti logo, orange tablets with a Batman bat logo, purple tablets with the JL Audio logo, and blue tablets with a dolphin logo); were also acquired during another undercover purchase from the same suspect (note that the four tablets in Photos 4 - 7 are all approximately the same size). The fourth submission consisted of 300 more of the same type tablets acquired in the third undercover purchase (43 green Infinitis, 52 orange Batman bats, 90 purple JL Audios, and 115 blue dolphins), that were seized pursuant to a consent search of the suspect’s room in a local motel. Analysis of the Bart Simpson and “Autobot” Transformer tablets by color testing (Marquis, secondary amine, and cobalt thiocyanate) and GC/MS, however, indicated not MDMA but rather a 1 : 3 : 1 mixture of N-benzylpiperazine (BZP), 1,3-trifluoromethylphenylpiperazine (TFMPP), and 1,4-dibenzylpiperazine, adulterated with caffeine. Analysis of the Infiniti, bat, JL Audio, and dolphin tablets (same techniques) indicated a 3 : 2 mixture of BZP and TFMPP (no 1,4-dibenzylpiperazine), again adulterated with caffeine. The various components were not formally quantitated, but were present at a fairly high loading based on the TICs. The Idaho State Police Forensic laboratories have received several similar submissions over the past few months.
