Effective Oct. 1, 2025, House Bill 687 — “Trenton’s Law” — transformed impaired-driving enforcement in Florida. While it appropriately toughens penalties for repeat DUI manslaughter, a secondary provision has created unintended fallout for lawful medical marijuana patients.
Prior to the bill, a first-time refusal to submit to a breath, urine or blood test triggered only an administrative driver’s license suspension. Under the revised Florida Statute 316.1939, a first-time refusal to submit to a test is now a standalone second-degree misdemeanor punishable by up to 60 days in county jail and a $500 fine.
The law creates a perilous trap for Florida’s 930,000 medical marijuana patients, which includes over 54,000 honorably discharged veterans.
The core problem lies in how long traces of cannabis can remain in the body. Active impairment lasts only a few hours, but THC metabolizes into inactive metabolites that can linger in urine for weeks or even months. Forensic toxicologists universally agree that a positive urine test for these metabolites proves only past exposure — not current impairment.
Yet standard procedure after a negative breathalyzer is to demand a urine sample. Trenton’s Law therefore traps lawful patients in a no-win paradox: Submit and risk DUI charges despite being unimpaired at the time of driving, or refuse and face an immediate criminal misdemeanor.
Critics may argue that defendants can simply present evidence in court to demonstrate that metabolites do not prove active impairment. However, this overlooks the practical realities of the criminal justice system. Most defendants appear pro se or with overburdened public defenders. Sophisticated scientific defenses are expensive, slow and lead to inconsistent outcomes across cases. Case-by-case litigation is not a viable systemic solution for more than 930,000 patients.
And even if a prosecutor promises not to mislead a jury into equating a positive test with active impairment, this does not resolve the trap. The refusal misdemeanor is a standalone crime, prosecutable even if no DUI charge is filed or proceeds to trial. Positive results are still introduced as leverage in plea negotiations, and the arrest and court burdens fall on patients long before any jury hears the scientific evidence. Individual prosecutorial discretion cannot adequately protect this large population.
Lawful patients who are fully compliant with Florida’s medical marijuana program — obtaining a valid physician certification, purchasing from licensed dispensaries and using cannabis exactly as prescribed — are nevertheless criminalized simply because of the lingering metabolites produced by their legal medication. Their adherence to state-approved medical treatment becomes the very thing that exposes them to prosecution, whether they submit to the urine test or refuse it under Trenton’s Law. This also invites serious Fourth Amendment challenges.
In Birchfield v. North Dakota, the U.S. Supreme Court held that warrantless breath tests incident to arrest are permissible, allowing states to criminalize refusal of a breath test. However, the Court ruled that warrantless blood tests are far more intrusive and cannot be justified as a search incident to arrest; states therefore cannot criminally punish refusal of a warrantless blood draw. The Supreme Court never addressed urine tests, leaving them in a constitutional gray area. With Trenton’s Law, Florida is betting courts will treat urine like breath.
But urine collection is far more similar to blood testing. Producing a urine sample invades profound privacy interests and reveals deeply personal medical information — from pregnancies to prescription drugs and genetic conditions.
Beyond civil liberties, the economic cost is enormous. Diverting thousands of nonviolent misdemeanor cases into the carceral system burdens county budgets. In Palm Beach County alone, the daily cost to house one inmate is approximately $135.
Even if courts ultimately uphold criminalizing urine refusal, Florida should adopt THC-free testing protocols for verified medical marijuana patients. When alcohol is ruled out, officers could use drug panels that screen for every other impairing substance — opioids, stimulants, etc. — while explicitly excluding cannabis metabolites.
While it is my legal opinion that this tailored approach would not cure the Fourth Amendment violation inherent in criminalizing refusal to provide a urine sample, it would nevertheless be a substantial improvement over what we are doing now.
Until active-THC detection methods (oral swabs or specialized breathalyzers) or targeted panels become standard, Florida’s state attorneys should immediately freeze prosecution of refusal charges against verified medical marijuana patients.
At the same time, local judicial circuits must expand pretrial diversion programs. Without these safeguards, Trenton’s Law will continue to impose an unjust toll on Florida’s lawful medical marijuana patients.
