"Anecdotal reports and preclinical studies suggest that certain cannabinoids may prove useful in treating the inattention and impulsivity seen in Attention Deficit Hyperactivity Disorder. Double-blind, placebo-controlled
studies are required to ascertain if this is indeed true."
– Julie Holland MD, Psychiatrist and Psychopharmacologist (USA, 2014)

can explore some of this evidence in the sub-pages of this section.
