Cannabis

Cannabis is a genus of flowering plants that produces bioactive compounds, including tetrahydrocannabinol (THC) and cannabidiol (CBD), making it important in research on perception, cognition, emotion, and behavior. THC primarily activates cannabinoid receptors in the brain, especially CB1 receptors, while CBD influences endocannabinoid signaling and other neural systems without producing the same intoxicating effects. In psychology, cannabis research examines how dose, frequency of use, developmental stage, and individual differences relate to attention, memory, mood, motivation, dependence, and mental health. These findings inform prevention, clinical assessment, therapeutic research, and public health policy.

Ultrasonic-assisted extraction (UAE) increases extraction efficiency of solvents and when applied to Cannabis spp. biomass it reduces the time required for extraction. This decreases the cost and potential cannabinoid loss due to degradation. Additionally, UAE is considered a green method due to low solvent use.

Oral administration via gavage in rodents can induce distress associated with restraint. We explored oromucosal/buccal administration of CBD-enriched Cannabis extract, where rats were treated for 15 days with the extract at 3 mg/kg/day. Treatments were administered orally with a micropipette, using an affectionate touch technique to handle the animals.

Cannabis distillate vape cartridges are battery-powered devices that aerosolize extracts containing high concentrations of cannabinoids. The absence of established preclinical models for these products creates challenges in studying their physiological effects. To address this gap, a standardized preclinical inhalation murine model for vaporized cannabis distillates has been developed.
