It is possible, and indeed it is the experience of most patients with substance-induced anxiety disorder, that they have used or been exposed to the substance or medication many times or for long periods of time without ever having experienced anxiety symptoms, in relation to the use of the substance or medication. Usually, the symptoms of a substance-induced anxiety disorder subside within 1 month after discontinuation of the substance.  However, it is not uncommon to experience the anxiety symptoms after the first month of discontinuation. In cases such as these, the diagnosis may change to another anxiety disorder, depending on the clinical picture of the patient.
