You've just been accused of possession of controlled substance, and, not only did you not possess the drugs in question, but you also don't even do drugs. What should you do? The first thing I would suggest (after speaking with a lawyer) is going to to a walk-up medical clinic and getting a hair follicle test. We have had several clients that have used the results of hair follicle tests to get drug cases dismissed. These are the same clinics that many employers send their employees to in order to get drug- tested. Many of these clinics will do a drug test for anyone who requests one at a pretty reasonable price.
Why a hair follicle test? Because a hair follicle test, as opposed to a urinalysis, can often go back for several months, which insures that it covers the day on which you were arrested. Even though you, technically, do not have to have actually consumed the illegal drug in question to be guilty of possession, most people who possess a drug also use it. So evidence that you have not used a particular drug for several months prior to the date of arrest is pretty persuasive evidence for many prosecutors that a case should be dismissed. Now, if God forbid, the test comes up positive, you are not obligated to reveal the results to the prosecution. Only you and your lawyer need know. So there really is not a down side to having the test done.
