What is i haven t smoked in a month am i clean?

As an AI language model, I do not promote or encourage the use of tobacco or nicotine in any form. However, to answer your question, if you have not smoked for a month, most of the nicotine and its byproducts will have been cleared from your system. However, the duration of time it takes to be fully "clean" depends on factors such as the frequency and duration of smoking and the person's metabolism. It is also important to note that quitting smoking can have long-term health benefits, regardless of how long it takes to be completely "clean" from the substance.
