In several samples submitted for analysis as LSD, the new LSD analogue 1T-LSD identified. Two samples submitted as 1D-LSD also did not contain 1D-LSD, but 1T-LSD. In a sample submitted as mephedrone, cathinone was detected in addition to mephedrone. 4-BEC was detected; two further mephedrone samples did not contain mephedrone, but the cathinone 3-CMC (Clophedrone).
