Tobacco use is a major public health concern, and understanding how long it lasts in your system is crucial for quitting and maintaining a healthy lifestyle. This article delves into the scientific evidence and provides practical guidance on eliminating tobacco from your body.

Nicotine Half-Life and Excretion

After consuming tobacco, nicotine is rapidly absorbed into the bloodstream. Its half-life, the time it takes for the body to eliminate half of the substance, is approximately 2 hours. Nicotine is primarily excreted through urine, with smaller amounts in feces, saliva, and sweat.

Route of Excretion	Percentage
Urine	80-90%
Feces	5-10%
Saliva	1-3%
Sweat	1-3%

How Long Tobacco Stays Detectable in the Body

The detectability of tobacco in the body depends on the type of test used and the time since consumption. Urine tests can detect nicotine for up to 3-4 days, while blood tests can detect it for a shorter period of up to 48 hours. Saliva tests have a detection window of 36-48 hours, and hair tests can detect nicotine for several months.

Test Type	Detection Window
