"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)

Supported by a wealth of anecdotal and pre-clinical evidence (some of which you can access on this website, many leading experts from both research and medicine now believe that the primary cannabinoid Tetrahydocannabinol (THC) in conjunction with other medicines found in cannabis causes improvements to focused attention in ADHD sufferers through the neuromodulatory process known as retrograde inhibition.

This is the same process used by the stimulant medicines currently prescribed extensively for ADHD (such as Methylphenidate and Dexamphetamine) where the neurotransmitter GABA is inhibited, thereby increasing Dopamine in the brain, which results in ADHD sufferers being able to concentrate. You can read an explanation of Dopamine and retrograde inhibition.

"I believe that cannabis is an excellent tool for ADHD and anyone who is doing further work on this I encourage. The more you learn about this the more you will understand that we are a long way from standardization of dosing. But I am very interested in participating in the research that is being done in this area as it is a disorder that runs rampant in the developed world."
