    I dont think cigarette stays in your system? But if it was weed and you only had it once it will probly stay there for a day or two

    nicotine begins to leave the system after 15 minutes I think.

    At 45 minutes or so it's totally out of your system.

    Most smokers have a cigarette every hour or so... which is tied to the approximate time at which their system is totally out of nicotine.

    Don't smoke, it will shrink your dick.
