Usually, it is thought that traces of tobacco can be detected within a person's saliva for anything between one to three days after the substance was last used.
However, the length of time that tobacco can be detected within someone's system will vary from individual to individual.
Everybody has their own natural metabolic rate - which will affect how long it takes for the body to cleanse itself of traces of tobacco.
The amount of tobacco you smoke, and how regularly you do so will also have a significant impact on the how long traces of the substance take to leave your saliva. A person's weight, gender and age will also have an effect on this.

How long can mouth swab tests detect tobacco for?
- As I mentioned earlier, tobacco can be found using mouth swab testing for about one to three days after the substance was last used.
- If you're being urine-screened for tobacco then, again, it could still be detected in your urine for up to three days.
- Hair follicle testing is used to determined a far longer-term drug history. This method of testing can find tobacco in the hair follicles for up to three months after it was last consumed.
