Question: What effects does marijuana use have on patients suffering from ADHD? Thesis: It is true that many people who suffer from ADHD also abuse substances and do not receive a correct diagnosis and do not receive adequate treatment. This is the most common co-occurring disorder and is very difficult to diagnose. Although the cause of ADHD is unknown, it is assumed to be a brain-based biological disorder; Substance abuse, however, is a combination of cognitive, behavioral, and physiological disorders. This combination also makes treatment difficult because people with the condition of ADHD have problems with controlling impulsive behaviors, paying attention, and some may be very active. According to recent statistics, it has been revealed that many people, especially those who abuse substances, do not receive treatment for ADHD. It should also be noted that patients with ADHD are at a greater risk of using illegal substances and medications and therefore need to receive the attention they need. It is also evident that people with drug addiction problems are often misdiagnosed and, as a result, do not receive the treatment they truly deserve. As noted by Millichap (2009), inadequate or improper treatment leads to impulsivity that drives people to turn to substances such as cocaine, marijuana, and other hard drugs for comfort. According to a number of these drug addicts, they confess that using drugs makes them feel high and better without knowing the dangers they face. Types of ADHD and Marijuana Use The case of children having concentration or behavior problems at particular stages of their childhood is considered normal. However, children with ADHD never grow up to... middle of paper... and this is being blamed as the cause of the link between ADHD and substance abuse. Likewise, medications used in the treatment of ADHD link them to the use of drug abuse. Depression resulting from ADHD causes people to abuse medications and bury their miseries in these medications without knowing how harmful they can be (Millichap, 2009). The only way to prevent such abuse is to avoid depression which will also lead to a lower chance of developing drug or alcohol abuse. Works CitedBrown, T. (2008).
