Effect of CBD on Learned Fear and Potential in Treatment of Post Traumatic Stress Disorder (PTSD)

"A growing body of literature provides compelling evidence that CBD has anxiolytic effects and recent studies have established a role for CBD in regulating learned fear by dampening its expression, disrupting its reconsolidation, and facilitating its extinction. The opposing effects of CBD on fear memory reconsolidation and extinction make it particularly attractive as a potential adjunct to psychological therapy as both may lead to lasting reductions in learned fear expression.

Known Therapeutic Benefits From Medicinal Cannabinoids

(Known Therapeutic Benefits From Medicinal Cannabinoids) "Cannabis preparations exert numerous therapeutic effects. They have antispastic, analgesic, antiemetic, neuroprotective, and anti-inflammatory actions, and are effective against certain psychiatric diseases. Currently, however, only one cannabis extract is approved for use. It contains THC and CBD [cannabidiol] in a 1:1 ratio and was licensed in 2011 for treatment of moderate to severe refractory spasticity in multiple sclerosis (MS).

Effects of State Medical Marijuana Laws (MMLs) on Youth Marijuana Use

(Effects of State Medical Marijuana Laws (MMLs) on Youth Marijuana Use) "We found no evidence of intermediate-term effects of passage of state MMLs on the prevalence or frequency of adolescent nonmedical marijuana use in the states evaluated, with 2 minor exceptions. From 2003 through 2009, adolescent lifetime prevalence of marijuana use and frequency of daily marijuana use decreased significantly in Montana, as compared with a more modest decrease in lifetime prevalence and an increase in daily frequency observed in Delaware (Ps = .03).

Youth Medical Marijuana Use and Unmet Health Needs

(Youth Medical Marijuana Use and Unmet Health Needs) "Of key importance in the findings are the unmet health needs of these youth. Health issues such as depression, insomnia, and anxiety were significant problems that interfered with these youths' ability to function at school, maintain relationships with family and friends, and feel that they could live a normal life. The level of distress associated with these health concerns, along with the lack of effective interventions by heath care providers and family members appeared to leave them with few alternatives.

Impact of Medical Marijuana Laws (MMLs) on Cannabis Use by Youth

(Impact of Medical Marijuana Laws (MMLs) on Cannabis Use by Youth) "We replicated the findings of Wall et al. (2) that marijuana use was higher in states that have passed MMLs, and our analysis suggests this is unlikely to be a causal association. Our difference-in-differences estimates suggest little detectable effects of passing MMLs on marijuana use or perceived riskiness of use among adolescents or adults, which is consistent with some limited prior evidence on arrestees and emergency department patients (17).
