No, it is not part of a physical, unless the doctor asks you if you smoke cigarettes.
No, Nicotine is the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. Nicotine is what keeps people smoking despite its harmful effects. Because the smoker inhales only some of the smoke from a cigarette and not all of each puff is absorbed in the lungs, a smoker gets about 1 to 2 milligrams of the drug from each cigarette. A drop of pure nicotine would kill a person-in fact, nicotine can be used as a pesticide on crops.
The only way it could be a part of a physical is if the doctor is asking you questions about smoking or checking for nicotine poison, but, as I said, no, it is not a part of a physical.
