This review provides the reader with an update on developments in research relating to cannabis psychosis. For over four decades researchers and clinicians have focused on the relationship between exposure to cannabis and the emergence of psychotic symptoms. This has proved to be a complicated topic to investigate but research has provided some valuable insights as to the nature of this...
Salvia divinorum is a hallucinogenic plant with ethnopharmacological and recreational uses. It differs from classic serotonergic hallucinogens such as LSD and psilocin in both phenomenology and potent agonist activity of the active component salvinorin A at κ-opioid receptors. Awareness of S. divinorum has grown recently, with both an increase in its public representation and concern over its...

This study examined subjective drug effects reported by different sub-populations of ecstasy users and explored whether the function or purpose served by using ecstasy influenced the nature of the drug...
National drugs information strategies convey the message that use of Ecstasy is associated with an increase in both the incidence and severity of major depressive disorder.

Ecstasy is the second most widely abused illegal drug in Europe. Ecstasy is the colloquial name for 3,4-methylenedioxymethamphetamine (MDMA), but not all Ecstasy tablets contain MDMA. When taken in hot, crowded environments, Ecstasy/MDMA users have developed acute complications that have had fatal consequences. Epidemiological evidence indicates that adverse reactions to Ecstasy/MDMA...
ABSTRACT Aims To examine the variation in the content of ecstasy tablets seized in the north‐west of England during 2001 and to compare it to the UK average from 1991 to 2001. Measurements All tablets submitted to the Forensic Science Service in the north‐west of England during 2001 were analysed by high performance liquid chromatography with diode array detection (HPLC‐DAD). The mean MDMA...
