OUI Drugs

Man looking in the rear view mirrorProsecuting OUI Drug Cases Are Harder Than Cases Involving Alcohol

Operating Under the Influence of Drugs  (OUI Drugs) is a serious criminal offense in Massachusetts that can result in jail time, fines, loss of your drivers license, and a criminal record. An OUI Drugs is very similar to a drunk driving or OUI alcohol case and we approach both cases essentially the same way.

The prosecution needs to prove the three elements in an OUI alcohol case in order to find a defendant guilty:

  1. The defendant was operating a motor vehicle;
  2. The defendant operated said motor vehicle on a public way; and
  3. The defendant was intoxicated or under the influence of drugs at the time of the operation.

Most police departments will charge a defendant with OUI Alcohol over OUI Drugs if they can. That is because it is easier for prosecutors to prove a defendant was operating under the influence of alcohol. However, each case is unique so we invite you to contact us for a free legal consultation so you can learn more about the charges you are facing and your best legal options.

The following are a few reasons why it is generally more difficult to prosecute an OUI Drugs case than an OUI Alcohol case.

Banned Drugs

“Under a unanimous ruling by the Supreme Judicial Court, Massachusetts police officers can no longer cite their subjective on-scene observations or sobriety tests to conclude in court testimony that a driver was under the influence of marijuana. In limiting the use of the familiar roadside tests designed to provide an approximate measure of drunkenness — walking in a straight line, standing on one foot, and so on — the court found there is no scientific consensus those tests definitively prove someone is intoxicated by marijuana.” Boston Globe

At trial, the prosecution is not allowed to allege that the defendant was simply under the influence of drugs. They have to prove beyond a reasonable doubt that the defendant was operating under the influence of one of seven banned categories of drugs:

  1. Central Nervous System Depressants(i.e., barbiturates, tranquilizers, and anti-anxiety medications like valium, librium, Xanax, klonopin)
  2. CNS Stimulants (i.e., cocaine, methamphetamines or amphetamines)
  3. Hallucinogens (i.e., molly, MDMA, or LSD)
  4. Dissociative Anesthetics (that turn the brains’ pain receptors off)
  5. Inhalants (i.e., glue, paint, and hair spray)
  6. Cannabis (aka pot, weed, marijuana)
  7. Narcotic Analgesics that increase euphoria and reduce pain (i.e., opium, heroin, morphine, codeine, Percocet, Oxycontin, and Vicodin)

Marijuana Exception

If the defendant does not have any of the drugs in the vehicle or on him then the police have no way of telling what drug the defendant was allegedly under the influence of. Marijuana is an exception, as it leaves a strong odor on the clothes and in the vehicle after it is smoked which allows police to charge OUI Marijuana even if there is no other evidence of marijuana use.

Lack of Trained Officers / Qualified Drug Recognition Experts

Usually only one, or only few police officers in each department are a qualified as a Drug Recognition Expert (DRE). DREs undergo extensive training which qualifies them to perform a set of tests in a standardized method which is supposed to allow a police officer to determine if a vehicle operator’s impairment is related to drug use. It involves a series of tests which include the following:

  • Series of Periodic Vital Signs Examinations: A person’s normal resting heart rate is anywhere between 60 and 90 beats per minute. Someone that is under the influence of stimulants like methamphetamines will have tachycardia (an abnormally high heart rate.)  Someone under the influence of an anti-anxiety medication like klonopin or a narcotic pain killer like Oxycontin will have bardycardia, which is an abnormally slow heart rate. The same goes for body temperature and blood pressure.
  • Dark Room Eye Examination: The muscles in our eyes allow our pupils to get bigger or smaller in response to changes in light levels. Drugs that are nervous system stimulants like cocaine cause our pupils to grow larger than normal (mydriasis) while central nervous system depressant drugs like heroin and Vicodin constrict our pupils which is known as Miosis. This dark room examination allows police to measure the pupil size as it reacts to changes in light. The change in pupil size is supposed to indicate the type of drug that was used.
  • Muscle Tone Examinations: certain drugs can cause our skeletal muscles to become rigid while other drugs like opiates and alcohol can nause them to become flaccid.

The average police officer is not a DRE; therefore, they cannot perform an examination or make a determination as to whether an operator of a vehicle was impaired due to drug use. The validity of these tests can be contested at trial as they are neither foolproof nor 100% accurate.

Police are trained to perform a series of field sobriety tests which were specifically developed to detect impairment due to alcohol. These tests are useless when it comes to detecting impairment by drugs.

Expert courtroom testimony is usually required in order for the prosecution to prove the defendant was under the influence of a specific drug. Expert testimony is also required to testify whether a specific drug is capable of diminishing a human’s ability to safely operate his or her vehicle. Police officers do not have the training or education to give this scientific testimony in court.
