Current evidence regarding the use of CBD for PTSD in humans is minimal. One case report showed that administration of 12–37 mg of oral CBD daily was associated with a reduction in anxiety symptoms and sleep disturbances in a 10-year-old patient with PTSD due to sexual trauma. 16 Another study showed that 32 mg of inhaled CBD resulted in consolidation of aversive memory extinction and attenuation of explicit fearful responding in healthy human subjects. 17 See Bittencourt and Takahashi 18 for a recent comprehensive review of pre-clinical and clinical studies regarding the relationship of CBD to PTSD. To date, no clinical trial evaluating the effectiveness of CBD in reducing symptoms of PTSD in humans has been completed.

Materials and Methods

P ost-traumatic stress disorder (PTSD) is a relatively common psychiatric condition with a lifetime prevalence of 6.1% in the United States. 1 PTSD often presents in clusters of symptoms, including the re-experiencing of traumatic events through intrusive memories and nightmares, avoidance of certain distressing factors, and alterations in mood, level of arousal, and cognition. Psychotherapy is the established first-line treatment for PTSD, and various psychiatric medications are also typically employed. The development of additional treatment agents is important because current medications, including selective serotonin reuptake inhibitors, serotonin/norepinephrine reuptake inhibitors, antiadrenergic agents, and second-generation antipsychotics, have questionable efficacy and often carry significant undesirable side-effect profiles.

We also predict that patients receiving the CBD Broad Spectrum formulation will show significantly greater improvement in PTSD symptoms and functional impairment relative to patients receiving CBD Isolate.

The biggest success story for CBD use in humans to date comes from controlled randomized clinical trials demonstrating a 50% or more reduction in previously intractable seizures in children suffering from Dravet syndrome and Lennox-Gastaut syndrome. Moreover, several controlled clinical trials have shown promising findings in reducing psychotic symptoms among patients with schizophrenia and among young adults displaying THC-induced psychosis.

We predict that patients receiving CBD isolate or CBD Broad Spectrum will show significantly greater improvements in PTSD symptoms and functional impairment at the posttreatment, one month, and three month follow-up assessments relative to patients receiving placebo oil. Additionally, we expect that patients receiving CBD Broad Spectrum will show significantly greater improvements relative to patients receiving CBD Isolate.
