Volume 177 , 1 August 2017, Pages 268-276 Reward-related frontostriatal activity and smoking behavior among adolescents in treatment for smoking cessation Author links open overlay panel Kathleen A.Garrisona One of the first longitudinal fMRI studies of smoking cessation treatment in adolescents. Adolescents show increased non-drug reward-related brain activity pre- to post-treatment. Increases in reward-related brain activity were associated with smoking abstinence. Tobacco use is often initiated during adolescence and continued into adulthood despite desires to quit. A better understanding of the neural correlates of abstinence from smoking in adolescents may inform more effective smoking cessation interventions. Neural reward systems are implicated in tobacco use disorder, and adolescent smokers have shown reduced reward-related ventral striatal activation related to increased smoking. The current study evaluated nondrug reward anticipation in adolescent smokers using a monetary incentive delay task in fMRI pre- and post- smoking cessation treatment (n = 14). This study tested how changes in neural responses to reward anticipation pre- to post-treatment were related to reduced smoking. An exploratory analysis in a larger sample of adolescents with only pre-treatment fMRI (n = 28) evaluated how neural responses to reward anticipation were related to behavioral inhibition and behavioral activation scales.

Tighter regulations on the beedi segment are being considered, he said. The authority estimates market share using surveys that are based on prevalence of use and not stick count. The government statistics are based on officially imported tendu leaves, according to Ridley. Since there has been evidence of a local source of tendu leaves as well as seizures of smuggled tendu leaves, these are “additional components” that need to be included in the calculation, she said. Some smokers of Capstan cigarettes, the company’s lowest-priced brand, have cut back on the number of sticks they buy after the price increases and also purchase beedis, said K.K. Badra, 58. She runs a kiosk that sells soft drinks, packaged snacks and other food items apart from tobacco products in Maligawatta, a Colombo suburb. Ceylon Tobacco is looking to contain the impact from higher levies. It has shut some of its leaf depots and reduced factory shifts to curb costs. To sustain profitability it’s working on “smart cost management, streamlining processes, identifying consumer segments and addressing their needs,” said Ridley.
