According to a recent study published in the South African Journal of Psychiatry, Attendion Deficit Hyperactivity Disorder (ADHD) is more common amongst patients who use cannabis than amongst patients seeking other substance abuse treatments. ADHD is a common childhood neurodevelopmental disorder characterised by early onset of impairing levels of hyperactivity, inattention, and impulsiveness. The study provides evidence of significant cannabis use, especially in females with ADHD, in treatment-seeking facilities in South Africa. It is widely reported that several mental health disorders are overrepresented amongst substance abuse populations. According to the study, South Africa needs to strengthen prevention and intervention activities against alcohol and cannabis use, especially in identified risk groups, like ADHD.
