M.A. / Literature indicates that childhood ADHD has received considerable attention and recognition in today’s society and is effectively represented in the DSM. In comparison, there is still much controversy surrounding ADHD in adults (aADHD), despite the fact that almost 50 to 70% of people diagnosed with childhood ADHD continue to manifest symptoms in adulthood. Research indicates that aADHD manifests differently to childhood ADHD, in that the core symptom is inattention and not hyperactivity. Research also indicates that there is a high comorbidity between aADHD and substance dependence, including nicotine dependence. It is hypothesized that these individuals present with hypodopamine, and nicotine acts on a number of neurotransmitter pathways, including the dopaminergic and acetylcholinergic pathways, effectively stimulating the release of dopamine. Whilst there is considerable literature on nicotine and ADHD, there is a complete lack of literature on the relationship between aADHD and Hookah Pipe smoking. This study aimed to rectify this situation. The present study was conducted with two major purposes in mind: (1) to investigate the relationship between Hookah Pipe smoking and its effects on attention and concentration in young adults with Attention Deficit/Hyperactivity Disorder (ADHD) symptomatology, and (2) to demonstrate whether Hookah has a greater effect than cigarettes (as Hookah reportedly has higher concentrations of nicotine than cigarettes). A total sample of 39 participants (14 males, 35 females) aged 18 to 26 years was recruited and divided into the following six groups using the ASRS, the Burke-Austin Self-Report ADHD Questionnaire and a substance abuse questionnaire as screening tools: ADHD (Hookah), ADHD (Nicotine), ADHD (Non-Smoking), Non-ADHD (Hookah), Non-ADHD (Nicotine) and Non-ADHD (Non-Smoking). Furthermore, a quasi-experimental research design was used, whereby the Cambridge Neuropsychological Test Automated Battery (CANTAB) ADHD Battery was administered across three test conditions, with a seven minute intervention between the pre- and post-intervention, and a 90 minute waiting period between the immediate and intermediate post-intervention, so as to test the effects of the nicotine as it neared its elimination half-life of two hours.

Attention-deficit/hyperactivity disorder (ADHD) is surrounded by confusion and controversy regarding its definition, course, etiology and treatment. Among adults, ADHD is rarely considered a diagnostic reality of primary importance and is often overlooked. This study provides descriptive validity for adult ADHD in distinguishing it from controls, and identifying both a pure condition and one wrought with comorbidity.

In this study 2 groups of adults, those with and without ADHD, were studied in terms of cognitive functioning and symptoms of ADHD, depression, anxiety, and substance abuse. Due to the difficulties in diagnosing ADHD in this population three methods of diagnosis were used and the resulting findings presented. The groups did not differ in measures of depression, anxiety, substance abuse or age. Those adults who met criteria for ADHD showed worse performance on a measure of response inhibition compared to those without ADHD. The patterns of correlations among the cognitive measures differed between the two groups. The conclusions from the findings are discussed in relation to Barkley's (1997) self-regulation model of ADHD.
