This is an open-label to double-blind study evaluating the effects of cannabidiol (CBD) for
the treatment of anxiety in adults. Participants will use a sublingual (under-the-tongue)
solution of whole plant-derived CBD or placebo three times daily for four weeks in addition
to their normal treatment regimen. Participants' clinical state will be assessed weekly
during the treatment period. In addition, cognitive function and measures of quality of life,
sleep, and general health will be assessed at baseline and the post-treatment final visit.
