P81 “Bath Salt” test updated to include Methylone. 10/11/11

Dear Client:
Effective October 11, 2011, Redwood Toxicology Laboratory (RTL) expanded the P81 test panel to include confirmation testing of Methylone (in urine).

The U.S. Drug Enforcement Administration (DEA) recently announced plans to invoke its emergency scheduling authority to temporarily control Mephedrone, 3,4 methylenedioxypyrovalerone (MDPV) and Methylone — 3 commonly found chemicals in designer stimulants marketed as "bath salts."

A recent statistical analysis performed at RTL supports the DEA's grounds for this ruling. Of positive specimens, RTL found 88% contained MDPV either alone or in combination with another designer stimulant. Methylone was the second most common at 29%, and Mephedrone was third at 4%.

The 3-drug P81 panel now aligns with the DEA's guidance and tests for the most commonly abused synthetic stimulants. RTL also offers a second expanded panel that detects 11 additional chemicals.

If you have any questions, please contact Client Services at: (800) 255-2159, ext. 4399.
