Smoking: How It Primes the Brain for Addiction

More and more people are now aware of the harmful effects on the body and the toxic effects of nicotine. The good news is that teenagers seem to be getting the news - SBB recently reported that smoking rates in the 8th, 10th and 12th graders are at historically low levels.

However, many teenagers are still smoking - According to the 2011 Monitoring Future Survey PDF [230 KB], 19% of high school graduates reported smoking last month

The new NIDA study provides another reason to avoid lighting to teenagers. The first cigarette - nicotine "guides" the brain to enhance cocaine, making it a very dangerous "portal drug". This means that it can open doors to other drug use

There is evidence that most people who have tried drugs like cocaine are tobacco or alcohol users. This concept of "portal drug" is controversial, because people question the future use of nicotine, alcohol or marijuana will lead to future drug abuse. Previously, the study did not show that the use of smoking and other nicotine could increase the biological opportunities of people using illegal street drugs.

The situation changed when NIDA researchers found that mice exposed to nicotine in drinking water increased the response to cocaine for at least 7 days.

Why is this happening? Researchers realized that nicotine actually changed the structure of DNA. It reprograms the expression of specific genes - especially genes related to poisoning - and eventually increases the response to cocaine.

Researchers examined the statistics of those who start using nicotine and its cocaine addiction in particular. Cocaine users who are smoking cigarettes before using cocaine are more dependent on cocaine than those who use cocaine. First (before smoking)

This research does not mean that all smokers eventually become addicted to cocaine. However, when smokers try cocaine, they indicate that their brain may be changing by nicotine.

Nicotine is a chemical that makes it possible to smoke a cigarette. When smoking a cigarette into the lungs, nicotine becomes very addictive, nicotine is quickly released into the bloodstream and enters the brain in a matter of seconds after smoking. In the brain, nicotine increases the release of chemical substances in the brain called neurotransmitters. This will help you adjust your mood and behavior. Cardiac and cardiovascular problems Smoking increases the risk of death from heart and blood vessels (cardiovascular) diseases including heart attacks and strokes. Smoking even 1 to 4 cigarettes a day increases the risk of heart disease. Symptoms may be exacerbated by smoking when heart diseases such as heart failure or vascular diseases are present. However, stopping smoking reduces the risk of heart attack by 50% in the first year.

Nicotine is very addictive, but people are controversial about the extent of its poisoning when it is separated from tobacco. When you suck smoke, nicotine will soon be transmitted to the blood and brain, creating a quick reward that the brain hopes over and over again. Tobacco smoke and other ingredients can increase the desire of smokers seeking more cigarettes. Other types of nicotine products can reduce the effects of poisoning. Therefore, the US Food and Drug Administration states that nicotine replacement therapy (NRT) such as gums and patches does not seem to have great potential for abuse or dependence.

Regardless of the route of administration, tobacco has a strong influence on the brain. When a smoker smokes tobacco smoke, it releases more than 4,000 chemicals, including nicotine and hundreds of other carcinogenic substances. After smoking nicotine will reach the brain in a matter of seconds. 3 Nicotine from chewing tobacco will take longer to reach the brain, as it must first be absorbed into the bloodstream through the gingiva. In any case, as nicotine reaches the brain it acts as a stimulant and releases excess neurotransmitters, including neurotransmitters associated with dopamine, joy and motivation, to the brain. People are addicted to nicotine even after several uses, as the brain regulates itself and produces some nicotine tolerance which must be achieved by drug addicts to maintain comfort. If this comfort is determined, the lack of nicotine in the brain can cause unpleasant withdrawal symptoms for the user.
