MDMA: interactions with other psychoactive drugs.

Pharmacology, Biochemistry, and Behavior October 2011 Wael M.Y. Mohamed, Sami Ben Hamida, Jean-Christophe Cassel et al.

3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) is one of the most widely abused illegal drugs. Some users self-report euphoria and an increased perception and feeling of closeness to others. When taken in warm environments, MDMA users may develop acute complications with potential fatal consequences. In rodents, MDMA increases locomotor activity and, depending on ambient temperature, may...

Identification of essential cannabinoid-binding domains: structural insights into early dynamic events in receptor activation.

Journal of Biological Chemistry September 23, 2011 Joong-Youn Shim, Alexander C Bertalovitz, Debra A Kendall

The classical cannabinoid agonist HU210, a structural analog of (-)-Δ(9)-tetrahydrocannabinol, binds to brain cannabinoid (CB1) receptors and activates signal transduction pathways. To date, an exact molecular description of the CB1 receptor is not yet available. Utilizing the minor binding pocket of the CB1 receptor as the primary ligand interaction site, we explored HU210 binding using lipid...

The fatty acid amide hydrolase inhibitor URB 597: interactions with anandamide in rhesus monkeys.

British Journal of Pharmacology September 2011 Jennifer L. Stewart, Lance R Mcmahon

The fatty acid amide hydrolase inhibitor URB 597 increases brain anandamide levels, suggesting that URB 597 could enhance the behavioural effects of anandamide. The goal of the current study was to examine and characterize the in vivo pharmacology of URB 597 alone and in combination with anandamide and Δ⁹-tetrahydrocannabinol (Δ⁹ -THC) in two drug discrimination assays in rhesus monkeys. The...

Drogeninduzierte Psychosen

Psychiatrie und Psychotherapie up2date August 18, 2011 Euphrosyne Gouzoulis‐mayfrank

All articles of this category Kernaussagen Psychotische Rauschverläufe und rauschüberdauernde drogeninduzierte Psychosen kommen bei einer Vielzahl von Drogen vor, die über verschiedene pharmakologische Akutmechanismen wirken. Hierzu gehören Cannabis, Stimulanzien, Ecstasy und Halluzinogene. In der Regel lässt sich aus klinischen und experimentellen Befunden eine Dosisabhängigkeit ableiten,...

A survey study to characterize use of Spice products (synthetic cannabinoids).

Drug and Alcohol Dependence August 10, 2011 Ryan Vandrey, Kelly E Dunn, Jeannie A Fry et al.

Background: Synthetic cannabinoids are a rapidly emerging class of abused drugs. Synthetic cannabinoids are typically sold as "herbal blends" or "incense," commonly referred to as Spice products. No controlled human experiments have been conducted on the effects of Spice products or the synthetic cannabinoids they often contain. Methods: An internet-based survey study was conducted with adults...

Event related potential (ERP) evidence for selective impairment of verbal recollection in abstinent recreational methylenedioxymethamphetamine (“Ecstasy”)/polydrug users

Psychopharmacology August 1, 2011 Adrian P. Burgess, Louise Venables, Helena Jones et al. 26 citations

Objectives Ecstasy is a recreational drug whose active ingredient, 3,4-methylenedioxymethamphetamine (MDMA), acts predominantly on the serotonergic system. Although MDMA is known to be neurotoxic in animals, the long-term effects of recreational Ecstasy use in humans remain controversial but one commonly reported consequence is mild cognitive impairment particularly affecting verbal episodic...

Drugs, altered states, and musical consciousness:reframing time and space

Oxford University Press eBooks July 28, 2011 Jörg Fachner 7 citations

This chapter discusses the psychedelic effects of drugs (mainly cannabis) on the perception and performance of music, and in particular how such drugs influence time perception in the process of performance. It focuses both on scientific studies and on anecdotal evidence provided by musicians and observers of musicians using drugs. Most of the material relates to developments in the American...

Effects of Endocannabinoid System Modulation on Cognitive and Emotional Behavior

Frontiers in Behavioral Neuroscience July 22, 2011 C. Zanettini, Leigh V Panlilio, M. Aliczki et al.

Cannabis has long been known to produce cognitive and emotional effects. Research has shown that cannabinoid drugs produce these effects by driving the brain’s endogenous cannabinoid system and that this system plays a modulatory role in many cognitive and emotional processes. This review focuses on the effects of endocannabinoid system modulation in animal models of cognition (learning and...

Reinforcing and neurochemical effects of cannabinoid CB1 receptor agonists, but not cocaine, are altered by an adenosine A2A receptor antagonist.

Addiction Biology July 2011 Zuzana Justinova, Sergi Ferré, Godfrey H Redhi et al.

Several recent studies suggest functional and molecular interactions between striatal adenosine A(2A) and cannabinoid CB(1) receptors. Here, we demonstrate that A(2A) receptors selectively modulate reinforcing effects of cannabinoids. We studied effects of A(2A) receptor blockade on the reinforcing effects of delta-9-tetrahydrocannabinol (THC) and the endogenous CB(1) receptor ligand anandamide...

Behavioral alterations in cystic fibrosis mice are prevented by cannabinoid treatment in infancy.

Journal of basic and clinical physiology and pharmacology June 17, 2011 Tatiana Bregman, Ester Fride

Substantial data have been accumulated regarding the molecular basis of cystic fibrosis (CF) pathogenesis, whereas the influence of biochemical impairments on brain processes has been the focus of much less attention. We have studied some behavioral parameters, such as motor activity and anxiety level, in a mice model of CF. We have assumed that functioning of the endocannabinoid system could...
