The gestational and adolescent periods are critically important for brain development and exposure to Δ9‑tetrahydrocannabinol (Δ9-THC) during these periods results in long term behavioral and biochemical abnormalities in laboratory animals. However, recent reports indicate a dramatic rise in oral Δ9-THC exposure in young children but the effects of this exposure scenario have not been...

Cannabinoid (CB) receptors are widespread in the nervous system and influence a variety of behaviors. Weakly electric fish have been a useful model system in the study of the neural basis of behavior, but we know nothing of the role played by the CB system. Here, we determine the overall behavioral effect of a nonselective CB receptor agonist, namely Δ9-tetrahydrocannabinol (THC), in the weakly...

Derivatives from the Cannabis plant are the most commonly abused illegal substances in the world. The main psychoactive component found in the plant, Δ-9-tetrahydrocannabinol (THC), exerts its effects through the endocannabinoid system. Manipulations of this system affect some types of learning that seem to be dependent on dorsal striatum synaptic plasticity. Dendritic spines exhibit important...

Alcohol, marijuana, and ecstasy (3,4-methylenedioxymethamphetamine [MDMA], 'Molly') are among the most prevalent substances used by young adults; however, few studies have focused on the specific sexual effects associated with use. Examining subjective sexual effects (e.g. increased libido) associated with use can inform prevention efforts. Data were analysed from 679 nightclub and dance...

Considering the increasing acknowledgment of the human sense of smell as a significant component of the quality of life, olfactory drug effects gain potential clinical importance. A recent observation in a human experimental context indicated that Δ9-tetrahydrocannabinol (THC) impaired the subject's performance in olfactory tests. To further analyze the role of THC in human olfaction, the...

Cannabis use has increased rapidly in recent decades. The increase in cannabis use makes it important to understand the potential influence of chronic use on attentional control and other executive functions (EFs). Because cannabis is often used to reduce stress, and because stress can constrain attentional control and EFs, the primary goal of this study was to determine the joint effect of...
