Effect of Oral pH Changes on Smoking Desire

Study Overview
=================
Brief Summary
-----------------
Nicotine is a psychoactive substance and its effect is demonstrated by neuronal nicotinic-acetylcholine receptors excreted in the brain and periphery. Psychoactive substances such as nicotine and caffeine play a role in rewarding through the mesolimbic dopaminergic system. The released dopamine produces pharmacological effects that can cause pleasurable emotions. These effects are an important factor in maintaining smoking motivation. The rate of absorption of nicotine from the buccal mucosa, the rate and amount of dependence, significantly affects the risk. In addition to PH, other factors such as local blood flow, product nematode, size and surface area of the tobacco mixture, constant pH holding capacity, and nicotine content of the tobacco can affect nicotine absorption. To facilitate the absorption of nicotine from the buccal mucosa, various substances that increase absorption have been investigated. Increased alkalinity has been shown to increase nicotine absorption and physiological effects by buffering alkaline pH values with moist snuff products and nicotine gums. Although other factors may affect the nicotine absorption rate in oral tobacco, it is stated that the main factor that determines the rate of nicotine absorption is pH. Factors that trigger nicotine use include stress in daily life, daily routines, eating and drinking habits, and especially the use of caffeine. The chronic use of caffeine causes tolerance in many of its effects, and the use of nicotine reduces tolerance effects and also potentiates the effects stimulated through the dopaminergic pathway. It has been reported that smokers consume more caffeine than non-smokers. In the present study, the relationship between oral pH and cigarette demand after caffeine consumption will be investigated. Until now, the relation between cigarette pre- and post-caffeine saliva pH and cigarette smoking has not been investigated. In addition, the effects of drinking behavior and changes in salivary pH on cigarette desire will be investigated and evidence of behavioral methods applied in cigarette smoking cessation treatment will be provided.

Detailed Description
-----------------
Nicotine dependence is accepted as the most common disease and can be treated with medical methods like other diseases. Scientifically proven pharmacotherapy as well as cognitive and behavioral therapy play an important role in reducing cigarette smoking. In this context, it is suggested that the motivation of the person should be questioned, the daily behavioral models should be questioned, the elements triggering the desire for smoking should be identified and the methods of combating them should be developed and the usual vital actions including eating and drinking should be organized. Consumption of acidic foods causes acidic pH in the mouth and salivation increases in order to neutralize it. After meals; tea or coffee, it was reported that smoking desire increases. Caffeine is another psychostimulant substance found in varying proportions in coffee and tea, and its antagonistic effects on the locomotor system are at adenosine receptors level. Stimulated at low doses and depressed at high doses. Nicotine has a stimulating effect on locomotor activity in chronic use. The chronic use of caffeine causes tolerance in many effects, and nicotine use decreases tolerance effects and also potentiates the effects stimulated through the dopaminergic pathway. It has been reported that smokers consume more caffeine than non-smokers. There are also studies reporting that there is no interaction between caffeine and nicotine and that cocaine consumption increases cigarette smoking as well as epidemiological studies that relate caffeine and nicotine concurrent consumption to pharmacological effects rather than pharmacological effects after food and between studies that are the two most common actions due to stress. However, this effect is not entirely due to the pharmacological effects of caffeine, but influences the intraoral pH and affects the cigarette smoking desire. In this study, the main aim is to investigate the effect of changes in salivary pH on the desire to smoke and how the drinking behavior of water affected this desire.
