Drug substitution: nicotine can be provided to the human body through nicotine substitution drugs, such as nicotine chewing gum, according to the doctor's advice, so as to achieve the purpose of partially or even completely replacing nicotine obtained from tobacco, which can effectively alleviate the nicotine withdrawal symptoms of smokers, and appropriately extend the treatment time for those with severe withdrawal reaction;
