Urine Test

Most people who are stopped or arrested for driving under the influence (DUI) in Florida will not be asked to submit to urine tests because breath testing is typically the much quicker and easier way to determine a person’s blood or breath alcohol concentration (BAC). Urinalysis may be required in suspected “drugged driving” cases in which alleged offenders are believed to be under the influence of a chemical or other controlled substance that would not appear in a breath test.

A urine test is not considered as invasive as a blood draw, but it is also usually not as accurate. Any one of a number of errors committed in the administration of a urine test or the storage or testing of the sample could impact the validity of the results and possibly lead to the test being declared inadmissible in court.

When a Person May Submit to a Urine Test in Florida

Whereas Florida Statute § 316.1932 (1)(a)1.a establishes a motorist’s obligation to submit to a requested breath test as the result of being a licensed driver in Florida, Florida Statute § 316.1932 (1)(a)1.b similarly states that the same licensed driver is expected to submit to a urine test when a law enforcement officer arrests him or her for any offense allegedly committed while that person was driving or was in actual or physical control of a motor vehicle while under the influence of a chemical or controlled substance.

An officer is required to inform an alleged offender that failure to submit to a lawful test of his or her urine will result in a one-year suspension of his or her driver’s license for a first refusal and other penalties if the person has previously refused test requests. A urine test is usually ordered only in cases in which people are suspected of being under the influence of illegal or prescription drugs, and the urine test is commonly conducted after a person has already submitted to a breath test.

In some cases, arresting officers may summon for the assistance of a Drug Recognition Expert (DRE) in evaluating an alleged offender and conducting urine tests. All people should understand that even when a urine test indicates that a person had a controlled substance in his or her system, the supposedly failed test is not necessarily evidence that substance was active at the time of the alleged offense.

Types of Problems with Florida Urine Tests

DUI Urine Test Lawyer

The major problem with urinalysis is that while the tests can prove a person consumed certain substances, the test results do not always indicate when that substance was consumed. As a result, it can be very difficult for a prosecutor to prove beyond a reasonable doubt that a person who submitted to a urine test and tested positive for a controlled substance was actually under the influence of that controlled substance while driving.

The Mayo Clinic states that the average detection times for some common controlled substances include:

Type of Drug Detection Time
Cocaine One day
Lysergic Acid Diethylamide (LSD) One day
3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy, or Molly) Two days
Ketamine Two days
Amphetamine Three days
Codeine Three days
Fentanyl Three days
Hydrocodone Three days
Marijuana (single use) Three days
Methamphetamine Three days
Morphine Three days
Oxycodone Three days
Flunitrazepam Five days
Marijuana (moderate use, or multiple times per week) Five days
Methadone Seven days
Phencyclidine (PCP) Eight days
Diazepam 10 days
Marijuana (heavy or daily use) 10 days
Marijuana (chronic heavy use) 30 days

Even if a person does test positive for a controlled substance, it should not be automatically assumed that the test result was accurate. In some cases, any one of a number of common errors can cause or contribute to possible false positives, including but not limited to:

  • Improper storage of sample;
  • Faulty or expired testing kit;
  • Sample too diluted;
  • Chain of custody issues;
  • Labeling or sealing issues;
  • Tampering with specimen; and
  • Contaminated sample.

As the article notes, Florida was one of at least 15 states to impose such requirements, but the 11th U.S. Circuit Court of Appeals in 2014 upheld a District Court ruling that permanently stopped enforcement of the law after determining it violated constitutional protections against unreasonable searches.
