Preclinical and experimental research suggests medicinal cannabis may help treat posttraumatic stress disorder, but integrating it into routine clinical therapies poses clinical, practical, and safety challenges, especially when combined with trauma-focused psychotherapy. Key issues include dose timing and titration, addiction potential, product formulation, windows of intervention, and route of administration. Exposure therapy for PTSD involves recalling intense emotions, and the interaction between cannabis use and reliving trauma memories requires exploration for patient safety and therapeutic outcomes.

A single oral dose of methamphetamine (20 mg) reduced blood levels of the endocannabinoid 2-AG in healthy adults, while MDMA (100 mg) did not. Neither drug affected anandamide (AEA) levels. Under placebo, higher AEA concentrations were linked to disliking the drug effects, suggesting a connection between AEA and negative expectations. These findings show how stimulants act on the endocannabinoid system and may inform treatments for substance use disorders.

Cannabis vapor inhalation acutely increases food intake in both humans and rats, an effect driven by central cannabinoid 1 receptors. In humans, energy intake rose within the first 30 minutes of snack access, regardless of dose or gender, without altering the proportion of macronutrients consumed. In rats, cannabis vapor reduced the time to start eating and increased the number of feeding bouts, overriding homeostatic appetite regulation by boosting motivation to eat and reducing food reward devaluation. These feeding effects were not accompanied by changes in circulating appetite-associated hormones, and they depended on central, not peripheral, CB1 receptors.
