For many smokers wish to quit smoking its strong, but it seems that no matter what they do, they just can not seem to eradicate this devastating habit. The incapacity to quit smoking causes many anxieties and damn people seems weakness.
A recent study found that people who are trying to quit smoking can get an attack of the itches. First off, most people even cigarette smokers don’t really enjoy smoking. For some the nicotine addiction is strong. Nicotine is very addictive, and breaking this addiction by not smoking can be very trying and difficult. Even after months have passed, there are those who will start smoking again. That’s why many smokers use several tools available to help them quit smoking. There is rubber, there are patches, and there’s even with nicotine inhalers.
It appears that nicotine patches used to help smokers kick the habit activate chemical pathways in the skin, nose and mouth that play a role in inflammation. The Belgian team, who studied the effects in mice, said that their findings could help others develop smoking cessation aids with fewer side effects. Scientists reported that Nicotine Replacement Therapy (NRT) gives the body nicotine without the harmful effects of smoking or chewing tobacco. The idea is to gradually lessen the addiction by using a low nicotine dose to take the edge off the cravings.
People who use nicotine patches or gum double their chances of successfully quitting, researchers showed. But some smokers do experience side effects even with NRT. For example, nicotine patches commonly cause skin irritation, and nicotine inhalers and nasal sprays may cause irritation in the mouth or nose.
Until now, scientists had thought that irritation came from stimulation of nerve receptors that transport painful influence from the skin and the linings of the nose and mouth. But Dr. Karel Talavera, of the Leuven Catholic University in Belgium, and colleagues found that in mice, nicotine also immediately activates TRPA1, a pathway or channel in cells known to carry information about irritating substances and stimulant pain.
They also discovered that mice lacking TRPA1 showed no irritation when nicotine was put into their noses. The researchers concluded: "Our results indicate that inhibition of TRPA1 represents an interesting approach for developing smoking cessation therapies with less adverse effects."
