SR 141716 (1 and 3 mg/kg p.o.), a selective central (CB1) cannabinoid receptor antagonist, selectively reduced feeding of a very highly palatable cane-sugar mixture in marmosets. In contrast, standard primate pellet intake was not modified at the lower dose, but was slightly increased (+29%;p <
The legalization of medical and recreational cannabis use has occurred ahead of science. The current evidence base has poor utility for determining if cannabis products can meet the standards of safety, efficacy, and quality intrinsic to modern medicine, and for informing regulation of cannabis as a
It has been suggested that the activation of cannabinoid receptors in the nucleus accumbens shell facilitates feeding behavior. However, it remains unclear whether cannabinoid ligands enhance the palatability of food to facilitate feeding. In this study, we examined whether microinjecting an
The effects of intraperitoneally injected detla9-tetrahydrocannabinol (THC), cannabinol (CBN) and cannabidiol (CBD) were compared to d-amphetamine sulfate (d-AMP) on food and water consumption and intake of two different concentrations of sucrose solutions. Three groups of rats were given the
Six adult male research volunteers, in two groups of three subjects each, lived in a residential laboratory for 13 days. All contact with the experimenter was through a networked computer system and subjects' behaviors, including food intake, were continuously recorded. During the first part of the
Cannabinoids purportedly improve taste responsiveness and enhance the sensory appeal of foods. These properties and a commonly cited oral drying effect were evaluated in a series of studies with 'light' marijuana users. The first was a double-blind, placebo-controlled, acute oral dosing trial,
Abnormal dopamine (DA) transmission in the striatum plays a pivotal role in attention-deficit/hyperactivity disorder (ADHD). As striatal DA signalling modulates the endocannabinoid system (ECS), the present study was aimed at investigating cannabinoid CB1 receptor (CB1R) function in a model of ADHD
As the purchase of cannabis becomes legalized in US states, cannabis marketing presents an unexplored regulatory landscape. Research examining other consumer products indicates marketing informs consumer product perceptions, use expectancies, and behavior. The current study examined The ability of Cannabis sativa (marijuana) to increase hunger has been noticed for centuries, although intensive research on its molecular mode of action started only after the characterization of its main psychoactive component Delta(9)-tetrahydrocannabinol in the late 1960s. Despite the public
The cannabinoid CB1 receptor antagonist SR141716A decreases cue-induced reinstatement of sucrose and drug seeking in rats. Reinstatement behavior is not well characterized in C57Bl/6 mice, including CB1 receptor knockout mice generated on a C57Bl/6 background. In the present study, male C57Bl/6, CB1
Although cannabinoid CB1 receptors (CB1Rs) are densely expressed in neurons expressing dopamine D1 receptors (D1Rs), it is not fully understood to what extent they modulate emotional behaviors. We used conditional CB1R knock-out animals lacking CB1Rs in neurons expressing D1R (D1-CB1(-/-)) in order
BACKGROUND
Recent studies in animals have implicated endogenous cannabinoids in the regulation of palatable food intake, but it is not yet clear to what extent pharmacological agents acting on this system may have sustained actions and applicability to different feeding protocols.
OBJECTIVE
In the
BACKGROUND
Despite evidence of school effects on drug use, little is known about the social and institutional processes through which these may occur. This study explores how school experiences may shape young people's drug-related attitudes and actions and adds to existing evidence highlighting the
High intake of fats and sugars has prompted a rapid growth in the number of obese individuals worldwide. To further investigate whether simultaneous pharmacological intervention in the leptin and cannabinoid system might change food and water intake, preferences for palatable foods, and body weight,
