Because some strands of cannabis are known to have relaxation properties, scientists and researchers are beginning to suggest medical marijuana may be useful in easing the symptoms of hyperactivity, lack of focus, and impulsivity that ADHD patients experience. One study from Germany in 2015 pooled 30 patients who did not respond well to Adderall and Ritalin, and found cannabis treatment improved patients' concentration and sleep, and reduced impulsivity. Co-author of the study and psychiatrist Dr. Eva Milz said pharmaceuticals were too demanding on patients, and cannabis allowed patients the "control that helped them in life, love and work, without feeling intoxicated."
Although further research is desired, these results suggest cannabis can be used alone or combined with stimulants for the treatment of ADHD. Not only could cannabis help manage the symptoms of ADHD, but it could also help manage the side effects of the stimulants like nervousness, loss of appetite, and sleep issues. Dr. David Bearman, however, suggests trying cannabis alone is better than using it to reduce the side effects of a supplementary medication, saying, "One of the important criteria in practicing medicine is to balance the side effects versus the therapeutic effects. The therapeutic effects of marijuana are the same or better than conventional drugs... and the side effects are much less."
