ADHD, Attention Deficit Hyperactivity Disorder, is a mental illness that involves difficulties with attention and self-control. This condition can affect different corners of a patient’s life. Medical researchers have found that marijuana use can help ADHD patients manage their symptoms such as agitation, irritability, etc. Unlike prescription medications, cannabis has fewer risks. In the United States, medical marijuana is legal in more than 30 states currently. To access state-licensed dispensaries, patients need to get MMJ letters signed by 420 doctors.
