DUI for Chemical Substances
Even Over-the-Counter Meds can Cause Drug DUI Trouble
DUI charges aren’t always for alcohol. They can also relate to the suspicion that a driver is under the influence of a chemical substance. Blood work can come back allegedly revealing the presence of marijuana, cocaine, meth amphetamine or some other substance. The drug may be legal, but if it is known to affect a person’s mental or physical capacities, a DUI charge may follow.
We have represented clients who were charged with DUI after using an over-the-counter cold medication. Believe it or not, zealous district attorneys have even sought DUI convictions for drivers whose coffee consumption resulted in a perceived impairment on the part of the arresting officer.
So what does it mean to be “under the influence” of a drug when you are behind the wheel? Most states, including Washington, recognize a drug as something that is capable of affecting the nervous system, brain, or muscles of driver, to the point where it is noticeable and affects a driver’s ability to drive his or her vehicle in the manner that compares to an ordinary driver in similar road conditions.
In Washington State, the Department of Motor Vehicles exercises jurisdiction over both alcohol and drug related DUIs. As part of this state’s aggressive stance against drug DUIs, the state employs drug recognition experts whom the state claims has special training in how to evaluate drug DUI suspects. The opinions of these “experts” are used to prosecute those who are accused of driving under the influence of drugs.
There are seven categories of drugs known to impact the central nervous system (CNS).
- CNS depressants have a similar effect as alcohol. They slow the brain and body down. Barbituates, tranquilizers and anti-depressants fall in this category.
- CNS stimulants have an opposite effect as alcohol. They speed everything up. Cocaine, “Crack”, Amphetamines and Methamphetamine (“Crank”) fall into this category.
- Hallucinogens change the perception of reality. LSD, Peyote, Psilocybin and MDMA (Ecstasy) fall in this category.
- Dissociative anesthetics cut off the brain’s ability to perceive pain. PCP is the most common dissociative anesthetic.
- Narcotic analgesics not only relieve pain, they produce euphoria and other mood changes. The most commonly known are Opium, Codeine, Heroin, Demerol, Darvon, Morphine, Methadone, Vicodin and OxyContin.
- Inhalants are mind-altering gasses that can be inhaled. Toluene, plastic cement, oil-based paint, gasoline, paint thinner, and hair sprays are common anesthetic gases.
- Cannabis (marijuana) distorts perception and impairs coordination. It also causes difficulty in thinking and problem solving.
If any of these substances are found in a driver’s blood after a DUI, Washington State prosecutors are going to take it very seriously. That is why is so vital to hire a DUI attorney with drug DUI experience. The prosecution is going to seek to prove that drugs impaired the driver’s abilities using the same tools used in an alcohol case, by pointing to circumstantial evidence.
Hire a DUI Attorney with Real Know-how.
When you hire a DUI attorney with real know-how, what might seem damning evidence to you may prove to argue for you. Circumstantial evidence is just that—circumstantial. It doesn’t always prove what the prosecutor wants it to. The prosecution may produce its drug recognition experts, but a DUI drug attorney will have the knowledge needed to point out the loopholes in the testimony.
Proving the level of impairment is still a very inexact science. It depends almost entirely upon the recorded statement of the arresting officer regarding the physical appearance, performance of field sobriety tests, observed driving behavior, incriminating statements and behavior at time of the arrest. There are no standards available.
Blood and urine tests aren’t definitive in many cases as well. While marijuana is usually identifiable, other drugs don’t always leave a clear marker to their identity. It is also worth noting that marijuana remains in the blood for weeks, so testing could falsely accuse a driver of being under influence when he or she isn’t. The mere presence of a drug in the blood or urine does not prove that enough of the drug was taken to cause mental and physical impairment.
How to Handle a DUI Arrest.
If you are arrested for a suspected drug DUI, expect for the arresting officer, or one of Washington’s drug recognition experts to record information about your pupil size, blood pressure, and pulse rate. Expect to have your arms examined for evidence of needle use. You can also expect to be pressured into admitting your drug use. Remember that something as small as admitting you took cold medicine could be used against you, so ask to speak with a DUI attorney before speaking with anyone. The less you say, the better.
Remain polite, yet don’t try to extricate yourself from the situation on your own. There are many reasons for an apparent drug DUI that have nothing to do with the use of a chemical substance. Seek the assistance of a criminal defense drug DUI attorney. It will make a difference for your future.
