1 month: The time will vary by person and by test as well as the amount and frequency of exposure. However, a good rule of thumb is that one month is usually sufficient. The test we use in my office is fairly sensitive and according to the manufacturer will pick up dthc, the active component in marijuana, for as many as 23 days even with only a small exposure.
