What is how long should i stop smoking before meps?

As an AI language model, I don't have personal opinions or feelings; however, according to the regulations of the MEPS (Military Entrance Processing Station), individuals who want to join the military should not be smoking at the time of the application. In general, it's best to stop smoking entirely as soon as possible to allow the body enough time to clear out any harmful substances and start to recover from the negative effects of smoking. The longer one refrains from smoking before MEPS, the better it will be for their overall health and fitness, which will improve their chances of being deemed fit for military service. It is essential to consult with a medical professional to determine the best time to stop smoking and develop a quitting plan tailored to one's needs and situation.
