Imagine being pulled over by the police, only to find yourself charged with driving under the influence (DUI) – not because of alcohol, but due to prescription medication or illegal drugs. This scenario is becoming increasingly common, and understanding the nuances of DUI drug charges is essential to protect your rights and navigate the legal system.

  2. Evaluating Evidence: A skilled DUI drug lawyer can critically evaluate the evidence against you, such as the procedures of any chemical tests, the administration of field sobriety tests, or the legality of the traffic stop itself, to identify any potential errors or violations of your rights that could lead to a dismissal or reduction of charges.
  3. Negotiating with Prosecutors: An experienced lawyer has the knowledge and negotiation skills to potentially reduce your charges, limit penalties, or even get the case dismissed based on their relationships with prosecutors and understanding of what is achievable in the local legal environment.
  4. Mitigating Consequences: Convictions for DUI drug charges can result in severe consequences, including loss of your driver’s license, hefty fines, and possible jail time.

Overview of DUI Cases Involving Controlled Substances

Understanding DUI Drugs: Prescription and Illegal Substances

When most people hear “DUI,” they think of alcohol. However, DUI drugs refer to both prescription drugs and illegal substances that can impair a driver’s ability to operate a motor vehicle safely. The distinction between these substances is crucial; prescription medications are permissible when taken according to instructions, while illegal drugs are always prohibited.

Regardless of whether the substance is legal or illegal, driving under the influence of any drug, including the influence of alcohol, can lead to severe consequences under DUI drug laws.

Prescription Medications and DUI

Prescription drugs, including some controlled substances, may be legally obtained and consumed, but they can still impair driving abilities and result in DUI charges. Painkillers, sleeping pills, and anti-anxiety medications are just a few examples of prescription medication that can lead to fatal crashes. These medications, as well as some over the counter drugs, often bear warnings on their labels, cautioning users that they may cause drowsiness or dizziness, and advising against operating motor vehicles or heavy machinery.

Even with a valid prescription, drivers must be cognizant of the potential side effects and warnings on prescription labels. In order to effectively defend against a prescription drug DUI charge, evidence must be presented to show that the individual was using the drug within its “therapeutic range”.

Illegal Drugs and Driving

Driving under the influence of illegal drugs is a criminal offense, and law enforcement officers are trained to recognize signs of drug impairment in drivers. Illegal drugs can be as hazardous as alcohol when driving, as they can affect one’s judgment, alertness, concentration, and motor skills. Common illicit substances that can result in a DUI include marijuana, heroin, cocaine, LSD, and methamphetamine.

It can be challenging to determine whether a driver’s unusual behavior is due to substance abuse or a mental health condition. Operating a vehicle while in a state of psychosis poses its own difficulties, but it does not constitute a DUI.

DUI Drug Laws and Enforcement

DUI drug laws vary by state, and in Florida, a person can be arrested and charged with a DUI if they are found to be under the influence of a prescription drug or illegal drug. These laws can be categorized into per se and impairment DUI laws.

Per se DUI laws proscribe driving with a specified degree of alcohol or drugs in the system, whereas impairment DUI laws are contingent on the actual effect the drugs or alcohol had on the driver. The act of enforcing these laws and detecting drug-impaired drivers heavily relies on the expertise of Drug Recognition Experts.

Per Se Drug DUI Laws

Per se drug DUI laws make it a criminal offense to operate a motor vehicle with a specific amount of THC or its metabolite in your system, without requiring proof of impairment. In certain states, per se laws apply to substances including cocaine, opioids, and methamphetamines. Establishing a per se DUI charge requires test results that show the quantity and type of substance in the driver’s body.

Colorado’s permissible inference law, for example, allows law enforcement to presume intoxication if a driver has 5 ng/ml of THC or a certain blood alcohol level in their system. However, the driver can contend in court that they are not impaired at this level.

Impairment DUI Laws

Impairment DUI laws focus on assessing the driver’s capacity to operate a vehicle safely, particularly when it comes to driving while impaired, and necessitate proof of impairment, including failed field sobriety tests or chemical tests.

Under Florida Statute 316.193, “normal faculties” are defined as a person’s capacity to:

  • walk
  • hear
  • see
  • talk
  • judge distances
  • make judgments
  • perform daily mental or physical tasks.

These laws emphasize the driver’s capability to drive a vehicle securely, and the penalties for drugged driving in Florida are comparable to those for a DUI for alcohol. It is illegal to drive while under the influence of drugs in every state, but the specific laws and penalties may vary.

Role of Drug Recognition Experts

Law enforcement officers, known as Drug Recognition Experts (DREs), are specially trained and certified to identify drug-impaired motorists. They follow strict guidelines to determine the level of impairment. These experts uphold DUI drug laws by detecting drug-impaired drivers and providing specialist testimony in court, thereby playing a pivotal role.

DREs can identify signs of drug impairment that may not be apparent to other officers, making their expertise invaluable in enforcing DUI drug laws and ensuring the safety of our roads.

Testing Methods for Drug DUIs

To ascertain drug impairment in DUI cases, different testing methods like blood, urine, and saliva tests are utilized. Each method has its advantages and limitations, and the choice of testing method may depend on the circumstances of the case, the specific drug involved, and the needs of law enforcement.

Blood Tests

Though intrusive and time-consuming, blood tests remain the most reliable method for detecting drug levels in a driver’s system. They measure the precise amount of drugs in the driver’s system, making them more accurate than urine or saliva tests, which only indicate the presence of drugs but not the exact amount.

However, blood tests require a sample of the driver’s blood to be taken and analyzed in a laboratory, which can take several days. Despite this inconvenience, blood tests remain the gold standard for determining drug impairment in DUI cases.

Urine and Saliva Tests

Urine and saliva tests are less intrusive than blood tests but may be less precise in determining drug impairment. Urine tests have a longer window of detection compared to saliva tests, which means they can detect drug use that occurred several days prior. However, urine test results may not be as reliable in correlating with impairment as blood and oral fluid testing.

Saliva tests are more accurate in detecting recent drug use, including cannabis. They can be a better indicator of recent drug use and may be more closely linked to impairment at the time of testing. However, oral fluid testing has some drawbacks, such as small sample volume and reduced salivation after drug intake, which can affect the accuracy of the test.

Penalties and Consequences of Drug DUI Convictions

Drug DUI convictions can result in both criminal and administrative penalties, including:

  • Fines
  • Jail time
  • License suspension
  • Mandatory substance abuse education

The severity of the penalties depends on the specific circumstances of the case, such as the driver’s prior convictions and the type of drug involved.

Criminal Penalties

Convictions for drug DUI, including a dui conviction, can result in the following criminal penalties:

  • Fines, which can range from approximately $200 to $2,000
  • Incarceration, with prison sentences that can range up to a year
  • Compulsory substance abuse education programs

Mandatory substance abuse education programs, often required by the national highway traffic safety administration for first-time offenders, aim to educate individuals about the dangers of drug-impaired driving and help them make safer choices in the future. These programs may also involve collaboration with the mental health services administration to address any underlying issues that could contribute to impaired driving.

Administrative Penalties

Administrative penalties are imposed by the Department of Motor Vehicles (DMV) and may include license suspension or revocation and the requirement to install an ignition interlock device. An ignition interlock device is a tool designed to prevent vehicle operators from driving while intoxicated. It requires drivers to submit a breath-test before the vehicle can be started. If any traces of alcohol are detected, the vehicle will not start..

In Florida, the penalties for a first conviction can include a fine of not less than $500 or more than $1,000. For a second conviction, the fine can be not less than $1,000 or more than $2,000, and subsequent convictions can result in higher fines and even jail time. Additionally, community service may be mandated for first-time offenders.

Defending Against Drug DUI Charges

In order to defend against drug DUI charges, one must:

  • Contest the prosecution’s evidence
  • Offer alternate explanations for the driver’s behavior or test results
  • Examine the drug testing procedure
  • Evaluate the validity of the evidence
  • Enlist the services of a knowledgeable DUI attorney who is familiar with the law and can contest the charges.

Challenging Evidence

One can challenge the accuracy of testing methods in drug DUI cases by questioning the reliability of the testing equipment, the accuracy of the results, or the competence of the personnel who conducted the tests. To challenge the qualifications of Drug Recognition Experts in drug DUI cases, one could inquire about their training, experience, or the accuracy of their observations.

In some cases, it may be possible to challenge the legality of the traffic stop itself, inquiring about the rationale for the stop, examining the officer’s behavior during the stop, or verifying the accuracy of the officer’s observations.

Presenting Alternative Explanations

Creating reasonable doubt in the minds of jurors can be achieved by presenting alternative explanations for a driver’s behavior or test results. This could potentially result in an acquittal or reduced charges. Alternative explanations can include medical conditions, environmental factors, or the use of other legal substances that may have affected the driver.

To introduce alternative explanations in court, evidence and testimony from qualified experts may be submitted. Successfully presenting alternative explanations can result in favorable outcomes for the defendant, such as an acquittal or reduced charges.
