A new study has been designed to help researchers track a tracer chemical, monamine oxidase (MAO), which will help those struggling to quit smoking. This enzyme has been found to play a crucial role in blood pressure and mood regulation has two subtypes MAO A and B.
The study showed that levels of MAO B in smokers' peripheral organs - the heart, kidneys, spleen and lungs - were reduced by 40 to 50 percent compared to non-smokers.
The results of tracking [MAO] A showed that is fairly well intact in all of the organs but the lungs. The levels in smokers were 50 percent lower than in non-smokers, and also smokers held onto the tracer much longer than non-smokers.
It means, for example... that your lungs are going to retain nicotine, that you're going to have a lower level of nicotine in your bloodstream than say a non-smoker, someone just starting out smoking.
So here's where smokers need to pay attention: lower blood concentration in smokers' lungs, as evidenced by their holding onto the enzyme-binding tracer, could be a possible factor behind why you eventually need to smoke more to get the same effect.
This new finding could be the basis of better treatments to quit smoking in the future.
