Primary Outcome Measures :
  1. Generalized Anxiety Disorder 7-item scale [ Time Frame: 12 weeks ]
    The Generalized Anxiety Disorder 7-item scale is one of the most frequently used, validated self-reported questionnaires that is used to screen for, diagnose, and assess severity of generalized anxiety disorder.

Secondary Outcome Measures :
  1. Perception of change [ Time Frame: 12 weeks ]
    Participants will complete the Patients' Global Impression of Change (PGIC) scale at each follow-up visit, which has been regarded as an important self-reported indicator of change.

  2. Protocol Compliance [ Time Frame: 12 weeks ]
    Participants will self-report their intervention compliance using a simple log that will be provided to them at their enrollment visit and will be asked to bring their CBD log to every follow-up visit. Participants will also self-report any medical cannabis or opioid usage.

  3. Sleep quality [ Time Frame: 12 weeks ]
    Participants will be asked whether they believe that the CBD intervention has impacted their sleep quality. They will be asked to complete a short 2-question survey.
