Introduction: Nicotine is the psychoactive substance responsible for establishing and maintaining smoking dependence. CYP2A6 is the primary enzyme that inactivates nicotine to cotinine .Genetic variation in CYP2A6 accounts for some of the inter-individual variability in nicotine metabolism and has been indicated to influence smoking behavior and dependence. Therefore, the aim of this study was ...

Background: The incidence of suicide is higher in individuals with post-traumatic stress disorder (PTSD) than the general population. This prevalence rate is related to many factors including drug dependence.

repetitive transcranial magnetic stimulation (rtms) has been used widely in various psychiatric disorders like depression and schizophrenia. there have been some reports of its usefulness in alcohol dependence and substance use disorders. the present paper reviews the studies done using rtms in substance use disorders including alcohol and nicotine dependence. various studies done have been rev...

Increased activity of mesolimbic dopaminergic system within ventral tegmental area (VTA) due to nicotine results in psychologic dependence. It has been argued that function of dopamine receptors could by affected by ascorbic acid (AA). Furthermore, AA can decrease the withdrawal syndrome signs in addicted animals and may postpone the development of nicotine dependence. In the present study, the...

Each CYP2A6 gene variant metabolizes nicotine differently depending on its enzymatic activities. The normal nicotine metabolizer CYP2A6(*)1A is associated with high scores of nicotine dependence (5-10) on the Fagerström Test for Nicotine Dependence (FTND) scale because it encodes for enzymes that catalyze nicotine 100%. Slow nicotine metabolizers (i.e., CYP2A6(*)1H, CYP2A6(*)4A, CYP2A6(*)9, and...

Since tobacco use is driven by dependence on nicotine, the primary addictive substance in tobacco, much research has focused on nicotine dependence. Less well understood, however, is the role that menthol plays in nicotine dependence. This review seeks to examine what role, if any, menthol plays in nicotine addiction in adults and youth. Based on research examining several indicators of heavine...

BACKGROUND Although nicotine dependence plays a role as a main barrier for smoking cessation, there is still a lack of solid evidence on the validity of biomarkers to determine nicotine dependence in clinical settings. This study aimed to investigate whether urinary cotinine levels could reflect the severity of nicotine dependence in active smokers. MATERIALS AND METHODS Data regarding genera...
