Approximately nine per cent of children and teens and five per cent of adults globally suffer from attention deficit hyperactivity disorder (ADHD).
This neurodevelopmental disorder is normally characterised by the inability to focus, or excessive hyperactivity and impulsivity. The condition normally disrupts learning in children, and adults with ADHD tend to be forgetful, suffer from anxiety, and experience mood swings.
ADHD is one of several disorders cannabis has shown much promise of treating. It is believed to be caused by a combination of factors that cause disruptions in the levels of dopamine, a neurotransmitter that controls memory and attention, and allows for the experiences of reward and motivation.
A 2010 study found that ADHD patients had fewer dopamine receptors and transporters in two areas of the limbic system – those responsible for emotion, and motivation/reward.
People with ADHD who self-medicate using marijuana are believed to experience positive results because THC naturally increases dopamine levels
