Brief Summary:
Despite the prevalence of cannabis use among the PTSD population and self-reports that it is used to help cope with PTSD symptoms, the direct effects of cannabis on PTSD symptomology are unknown. The purpose of this placebo-controlled, within-subject study is to assess the effects of smoked cannabis and orally administered nabilone, a synthetic analog of THC, the primary psychoactive component of cannabis on multiple dimensions of PTSD symptomatology in cannabis smokers with PTSD.

Condition or disease Intervention/treatment Phase
Cannabis Post Traumatic Stress Disorder Drug: Nabilone Drug: Cannabis Drug: Propranolol Drug: Placebo Phase 1 Phase 2

Detailed Description:
This study will compare the effects of smoked cannabis and nabilone on attentional bias toward trauma- related stimuli, subjective and emotional processing to a range of trauma-and non-trauma-related images and physiological reactivity to these stimuli in individuals with CUD and PTSD. Importantly, this study will also probe the abuse related potential of nabilone compared to smoked cannabis in this population, a critical aspect in determining the potential feasibility for its use clinically to treat CUD in PTSD populations. The effects of nabilone will be compared to propranolol as a positive control.

Estimated Enrollment : 14 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description: All patients will contribute to each of 4 drug conditions (placebo, nabilone, smoked cannabis, and propranolol).
