The Pharmacokinetics of Δ-Tetrahydrocannabinol in Sheep.

The pharmacokinetics of Δ-tetrahydrocannabinol (Δ-THC) has not been established in ruminants. Pharmacokinetic knowledge is important given feeding industrial hemp biomass has been shown to result in tissue residues post feeding in sheep. Due to a lack of testing and available data, a 'maximum' concentration of Δ-THC has not been currently set for foods of animal origin.

Detecting ketamine in beverage residues: Application in date rape detection.

Ketamine can be used to facilitate date-rape when unknowingly spiked into a victim's beverage. If a biological sample is not available from the victim, the beverage container might be the only remaining source of forensic evidence. We present a rapid, simple analysis method for the detection of ketamine in wet or dry beverage residues based on liquid chromatography-mass spectrometry (LC-MS).
