One of the advancements regarding this matter is the introduction of nicotine patches. These patches help quench the smoker’s appetite for nicotine as it provides steady inflow of the chemical without puffing a cigarette, and it also decreases the symptoms of nicotine withdrawal. These patches are applied topically to the upper part of a client’s body, usually on the upper arm, everyday. A single patch is taken off in the evenings to give the person’s bloodstream a rest from the influx of nicotine. There are some brands though that can be worn in the nighttime.
