People with ADD/ADHD are also often hyperactive. Many patients of the condition exhibit all three qualities.
Marijuana may be beneficial for helping ADD/ADHD patients stay focused and remain attentive. Proponents of medical marijuana use also claim that it may help control hyperactive or impulsive behavior.
