Pseudoephedrine (PSE) salts (hydrochloride and sulfate) are commonly used as nasal and paranasal decongestants by scuba divers. Anecdotal reports from the Divers Alert Network suggest that taking PSE prior to diving while breathing pure O₂ increases the risk for CNS oxygen toxicity (CNS-OT), which

BACKGROUND
Clandestine laboratory operators commonly extract ephedrine and pseudoephedrine-precursor chemicals used to synthesize methamphetamine-from over-the-counter cold/allergy/sinus products. To prevent this activity, two states, Oregon in 07/2006 and Mississippi in 07/2010, implemented

OBJECTIVE
Pseudoephedrine is a precursor often diverted into the illegal manufacture of amphetamine type substances (ATS). The aim of this study was to evaluate the effectiveness of a linked electronic medication recording system (LEMS) established in Australian pharmacies in 2005 for preventing the

Ephedrine/pseudoephedrine (EPH) is the most common precursor for the manufacture of methamphetamine and is controlled within China via criminal law and government regulations. Therefore, it is of great significance to systematically study the cases of illicit production of EPH in order to aid timely
The use of cyclohexanone as a "derivatizing" reagent for the GC-MS detection of amphetamines and ephedrines in seizures and the urine.
