Quote from a previous comment here:
"Many suspected MDMA tablets or capsules actually turn out to contain something else these days."
Here is another example of suspected MDMA actually turning out to be something else after a field test that is positive for MDMA.
Note that ecstasy is another name for MDMA.
Case 2:08-cr-20621-JAC-RSW Document 78 Filed 03/06/10
"According to the Government, Beckley recruited his cousin, Shantell Johnson, and her friend, Albany Cooper,6 to travel to Canada where they were instructed to pick up approximately five thousand (5,000) ecstasy pills, and smuggle them into the United States."
"A field test of the pills by a border patrol officer produced a positive result for ecstasy."
"On November 25, 2008, Beckley was officially accused by a grand jury of violating 21 U.S.C. §§ 846 and 841(a)(1); namely, conspiring with other persons to distribute MDMA. However, with an apparent recognition that a subsequent analysis of the confiscated “ecstasy” pills by the Drug Enforcement Administration (“DEA”) revealed that they actually contained a combination of other chemicals (i.e., BZP, TFMPP, and caffeine), the Government subsequently filed a superseding indictment in which Beckley was accused of having conspired with other persons to distribute BZP."
Note that Joseph P Bono is mentioned in the above link.
He is also mentioned in the sun-sentinel article:
