ABSTRACT: Drug self-administration behavior has been one of the most direct and productive approaches for studying the reinforcing effects of psychoactive drugs, which are critical in determining their abuse potential. Cannabinoids, which are usually abused by humans in the form of marijuana, have become the most frequently abused illicit class of drugs in the United States. ... Continue Reading

STUDY: Cannabinoid 2 (CB2) receptor involvement in the down-regulation but not up-regulation of serum IgE levels in immunized mice
ABSTRACT: Marijuana cannabinoids such as Δ9-tetrahydrocannabinol (THC) have been shown in experimental systems to bias T helper immunity towards Th2 and away from Th1. This effect if broadly applicable to humans could have important implications in Th2-mediated diseases such as allergy. In the current study, we examined the effect of cannabinoids on serum immunoglobulin IgE ... Continue Reading
STUDY: Blunted Psychotomimetic and Amnestic Effects of Δ-9-Tetrahydrocannabinol in Frequent Users of Cannabis
ABSTRACT: BACKGROUND Cannabis is one of the most widely used illicit substances and there is growing interest in the association between cannabis use and psychosis. Delta-9-Tetrahydrocannabinol (Δ-9-THC) the principal active ingredient of cannabis has been shown to induce psychotomimetic and amnestic effects in healthy individuals. Whether people who frequently use cannabis ... Continue Reading
STUDY: Emerging Role of the CB2 Cannabinoid Receptor in Immune Regulation and Therapeutic Prospects
ABSTRACT: There is now a large body of data that indicates that the CB2 cannabinoid receptor type 2 (CB2) is linked to a variety of immune functional events. This functional relevance appears to be most salient in the course of inflammation, a process during which there is an increased number of receptors that are available for activation. Studies aimed at elucidating signal ... Continue Reading
STUDY: Cannabinoid CB1 Receptor Agonists Do Not Decrease, but may Increase Acoustic Trauma-Induced Tinnitus in Rats
ABSTRACT: Tinnitus has been suggested to arise from neuronal hyperactivity in auditory areas of the brain, and anti-epileptic drugs are sometimes used to provide relief from tinnitus. Recently, the anti-epileptic properties of the cannabinoid drugs have gained increasing interest; however, the use of cannabinoids as a form of treatment for tinnitus is controversial. In this ...
