What Are the Penalties for Fentanyl Possession in Florida?

 Posted on May 07, 2026 in Drug Crimes

Selling, making, transporting, or otherwise dealing in fentanyl is one of the most aggressively prosecuted drug crimes in Florida. Even a small amount can lead to felony charges. Going over certain weight limits turns a possession case into a trafficking charge with mandatory prison time that a judge cannot reduce. If you are facing a fentanyl charge in 2026, a Miami, FL criminal defense attorney can help you understand what you are up against and start building your defense.

How Does Florida Classify Fentanyl as a Controlled Substance?

Florida law lists pharmaceutical-level fentanyl and certain analogs as Schedule II controlled substances under Florida Statute § 893.03. Other fentanyl analogs are Schedule I substances under the same law. Schedule II drugs have some accepted medical uses but carry a high risk of addiction and abuse. Schedule I drugs have no accepted medical use and a high potential for abuse. Having any amount of fentanyl of any kind without a valid prescription can lead to criminal charges.

What Are the Penalties for Possessing Less Than 4 Grams of Fentanyl in Florida?

Possessing less than four grams of fentanyl is a third-degree felony under Florida Statute § 893.13. A third-degree felony carries up to five years in prison and fines up to $5,000. This applies even if the drug was for personal use and there was no plan to sell it.

The law counts the total weight of any mixture containing fentanyl, not just the weight of the fentanyl in it. So if fentanyl is mixed with another substance, every gram of that mixture counts toward the threshold. A small amount of fentanyl in a larger mixture can push the total weight into trafficking range faster than most people expect.

When Does Fentanyl Possession Become a Trafficking Charge in Florida?

Once the weight of fentanyl or a mixture containing fentanyl reaches 4 grams, Florida law treats it as trafficking. It does not matter whether someone actually planned to sell it. Possession alone at that weight is enough for a trafficking charge.

Florida has treated fentanyl as a serious public safety issue for years, and the penalties reflect that. According to the Florida Department of Law Enforcement 2023 Annual Drug Report published in 2025, fentanyl was involved in 4,962 deaths in the state that year, more than any other drug. That death toll is one reason the state has some of the harshest fentanyl penalties and why prosecutors often pursue these cases aggressively.

What Are Florida's Mandatory Minimum Sentences for Fentanyl Trafficking?

Under Florida Statute § 893.135, fentanyl trafficking carries set prison terms based on the amount involved. These are called mandatory minimums, which means a judge usually must impose them unless the prosecutor allows a lower sentence in limited situations. The minimums went up sharply after changes to the law in 2023, and a judge cannot go below them unless the prosecutor agrees to waive them as part of a plea deal.

The thresholds break down as follows:

• 4 to 14 grams: minimum 7 years in prison and a $50,000 fine.
• 14 to 28 grams: minimum 20 years in prison and a $100,000 fine.
• 28 grams or more: minimum 25 years in prison and a $500,000 fine.

Certain aggravating factors, like trafficking to minors or trafficking that results in death, can be punished with life in prison.

What Defenses Are Available for a Fentanyl Charge in Miami?

The outcome of a fentanyl case depends heavily on how the drugs were found, how the evidence was handled, and what the state can actually prove. Common defense approaches include challenging the search or traffic stop that led to the discovery of the drugs, arguing that the accused did not knowingly possess the fentanyl, disputing the lab testing or how the evidence was stored, and contesting the weight used to set the charge level. In trafficking cases, helping law enforcement is one of the few paths to getting below a mandatory minimum. A defense attorney can also look at whether the facts support dropping the charge from trafficking down to simple possession.
