People are addicted to nicotine even after several uses, as the brain adjusts 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.
