Inhibition of the metabolism of the endocannabinoids, anandamide (AEA) and 2-arachidonyl glycerol (2-AG), by their primary metabolic enzymes, fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), respectively, has the potential to increase understanding of the physiological functions of the endocannabinoid system. To date, selective(More)
It is well established that genetic deletion or pharmacological inhibition of the CB(1) receptor disrupts extinction learning in aversive conditioning tasks, but not in appetitive tasks. Consistent with these findings is that genetic deletion or pharmacological inhibition of fatty acid amide hydrolase (FAAH), the primary catabolic enzyme of the endogenous(More)
CB 1 receptor-compromised animals show profound deficits in extinguishing learned behavior from aversive conditioning tasks, but display normal extinction learning in appetitive operant tasks. However, it is difficult to discern whether the differential involvement of the endogenous cannabinoid system on extinction results from the hedonics or the required(More)
Repeated marijuana use is known to lead to physical dependence in humans; however, its dependence liability has yet to be adequately assessed in laboratory animals. The goals of the present study were to: assess whether the CB(1) antagonist SR 141716 (rimonabant) precipitates withdrawal in mice that had been repeatedly exposed to marijuana smoke, and to(More)
