This section deals with research relating to Cannabis and Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD). Medical consensus is not well established about treating ADD/ADHD with Cannabis, so many of the studies attempt to understand which subtypes of ADD/ADHD are self-medicating with Cannabis and where they’re getting the information.

What is Attention Deficit Disorder?

Attention-deficit disorder, compressed into the now wider-reaching Attention-Deficit Hyperactivity Disorder, is a mental disorder of the brain-development type. It’s characterized by difficulty paying attention, excessive activity and difficulty controlling behavior. The symptoms of ADHD must first occur before a person is 12 years old. ADHD is difficult to diagnose an exhibits differently in boys and girls. Symptoms of ADHD will continue into adulthood for 30-50% of those diagnosed as children.

What is known about Cannabis and ADD/ADHD?

The online community seems to feel strongly that Cannabis is medication for ADD/ADHD. Unfortunately, with little to no research supporting this belief, it’s difficult to draw conclusions. Some studies do seem to show that it has some effect on the “hyperactive” subtypes of the ADD/ADHD spectrum. Ideally in the near future, properly designed studies will attempt to identify which types of ADD/ADHD could be treated by Cannabis, and which compounds in Cannabis are best for that treatment.
