Urine Test

Most people associate drinking and driving arrests with breathalyzers. However, officers can also measure your blood alcohol concentration using urine analysis. Law enforcement often use urinalysis to identify those driving under the influence of drugs (DUID). It’s also used as a last resort if a breathalyzer test doesn’t result in a positive.

Urinalysis isn’t a foolproof test. Lab technicians and other personnel could make results which lead to skewed results. In addition, if you have used a controlled substance recently then the rest could be positive even if you used the substance days ago. This is because drug’s metabolites can remain in your system for days.

If you or someone you know has refused or submitted to a urine test, then it’s important you seek an experienced criminal defense attorney.

Issues with DUI Urine Analysis in Florida

Law enforcement may use urine analysis, but unfortunately it isn’t flawless. Urinalysis can detect substances that was consumed days or even weeks ago. Therefore, it can be very difficult to obtain an uncontaminated sample. The skewed results could even reinforce the prosecution’s case even if you haven’t consumed drugs or alcohol in days.

Controlled substances can stay in your system long after you ingested them. Listed below are some detection times for common controlled substances.

Type of Drug: Detection Time
Cocaine One day
Lysergic Acid Diethylamide (LSD) One day
MDMA, Ecstasy, or Molly Two days
Ketamine Two days
Codeine Three Days
Amphetamine Three Days
Hydrocodone Three Days
Fentanyl Three Days
Methamphetamine Three Days
Oxycodone Three Days
Morphine Three Days
Flunitrazepam Five Days
Moderate Marijuana Use Five Days
Methadone Seven Days
Phencyclidine (PCP Eight days
Diazepam 10 days
Marijuana Daily Use 10 days
Marijuana Chronic Use 30 days

Detection times aren’t the only factor that can skew test results. Human error made by lab technicians or law enforcement can also lead to false positives such as:

  • Sample isn’t stored properly;
  • Diluted samples;
  • Issues with sealing the sample; or
  • Tampering with samples;
  • Contaminated samples;
  • Badly read results;
  • Expired testing kits; and
  • Faulty testing kits

Should I Refuse Urine Analysis for a DUI Stop in Florida?

You’re probably wondering whether you should submit or refuse whenever an officer asks for a urine sample. The answer is up to you, but it’s important you understand the facts. Refusing urine testing means you’re less likely to be charged with DUI, but it comes with its own consequences because of implied consent laws.

Implied consent laws state you must submit to chemical DUI testing by law enforcement if you are using public roads in Florida. Refusing to submit to DUI testing will lead to an administrative license suspension for up to one year. A second refusal could mean an 18-month suspension.  Thankfully, you can fight this by filing a request for a hearing within 15 days of receiving your suspension term. At the hearing you can contest why you should retain your license.

It’s important to note that if you submit and fail to a chemical DUI test then it will reinforce the prosecution’s case. They will now have concrete evidence that shows you are inebriated. The consequences for a DUI conviction include:

  • Up to six months in jail;
  • A possible fine between $500 and $1,000;
  • Up to 12 months of probation;
  • Possible impoundment of motor vehicle for up to 10 days;
  • Participation in DUI School;
  • Possible requirement of an ignition interlock device.

In addition, your license could still be suspended. Submitting and failing a DUI test can lead to a 6-month suspension term.
