Since October 1, 2026, selling or holding xylazine (the veterinary sedative known on the street as tranq) with intent to sell is a first-degree felony in Florida with a 3-year mandatory minimum prison term, and 28 grams or more is trafficking, with mandatory terms that climb to 25 years. Separately, since July 1, 2026, fentanyl test strips are legal to carry: a second law removed them from the definition of drug paraphernalia. Both changes came out of the 2026 legislative session and both are now in force in Miami-Dade.
What the xylazine law says
Senate Bill 432, signed June 16, 2026 and published as Chapter 2026-148, does three things to xylazine. It keeps the drug on Florida’s Schedule I while carving out FDA-approved veterinary products, a change effective July 1, 2026. It makes selling, manufacturing, delivering or possessing xylazine with intent to deliver a first-degree felony with a 3-year mandatory minimum. And it creates a new offense, trafficking in xylazine, with penalties set by weight, according to the Senate Criminal Justice Committee’s summary of the bill:
- 28 grams to under 100 grams: 3-year mandatory minimum and a $100,000 fine
- 100 grams to under 200 grams: 7-year mandatory minimum and a $100,000 fine
- 200 grams or more: 25-year mandatory minimum and a $500,000 fine
The criminal provisions took effect October 1, 2026. A mandatory minimum means the judge cannot go below that number, no matter the person’s record or circumstances.
Why 28 grams is a low bar
Xylazine is rarely sold on its own. It shows up as a cutting agent in street fentanyl, and Florida’s trafficking statute, section 893.135, has always measured weight by the whole mixture, not by the pure drug. A single bag of fentanyl cut with tranq that weighs an ounce can therefore support a xylazine trafficking charge, on top of the fentanyl trafficking charge for the same bag. The two mandatory minimums are separate.
That stacking is the practical change for Miami-Dade. Before October 1, a person arrested with a mixed bag faced fentanyl trafficking exposure. Now the same arrest can produce two trafficking counts from one weight, and the xylazine count carries its own floor of three years.
Meg’s Law: nitrous oxide at smoke shops
The same bill carries a second provision, named Meg’s Law after a 29-year-old Orange County woman who died after a nitrous oxide addiction, according to WUSF. Since October 1, 2026, a licensed tobacco or nicotine retailer (a smoke shop, a gas station, a convenience store) commits a third-degree felony by possessing, selling or giving away nitrous oxide on its premises. Grocery stores and supermarkets are exempt, and food products that use nitrous as a propellant, such as whipped-cream chargers sold for cooking, are not covered.
This is a change in kind, not degree. A smoke shop in Hialeah or Little Havana that keeps flavored nitrous canisters behind the counter is no longer risking a code citation. The employee who hands one across the counter is risking a felony arrest, and a third-degree felony in Florida carries up to five years in prison.
Are fentanyl test strips legal in Florida?
Yes, since July 1, 2026. House Bill 477, published as Chapter 2026-157, amends section 893.145, the definition of drug paraphernalia, to exclude test products used to detect fentanyl, fentanyl analogs or xylazine. The bill passed the House 116 to 0 and the Senate 34 to 0.
Before this change, a test strip found in a pocket or a car could be charged as possession of paraphernalia, a first-degree misdemeanor that was a common add-on count in Miami-Dade drug arrests. That charge is gone for test strips. A person who carries them to check a supply for fentanyl or tranq cannot be prosecuted for the strips themselves.
The exclusion covers the test products only. Pipes, scales, baggies and the drugs themselves are charged exactly as before.
What this means if you are charged in Miami-Dade
If you were arrested on or after October 1, 2026 with a mixture that contains xylazine, ask your lawyer two questions at the first meeting: what does the lab report say the mixture contains, and what did the whole thing weigh. Those two facts decide whether the case is a possession charge, a first-degree felony with a 3-year floor, or a trafficking charge with a 3, 7 or 25-year floor. The weight is measured at arrest, not after the fentanyl is separated out.
If the arrest was before October 1, 2026, the new xylazine offenses do not apply to it. Florida does not apply new criminal penalties backward.
If you work at a smoke shop or convenience store, the nitrous oxide ban applies to the business and to the person who makes the sale. “The owner told me to” is not a defense to a felony, though it matters at sentencing.
If a paraphernalia count in your pending case is based only on fentanyl or xylazine test strips, that count should be dismissed. The law changed on July 1, 2026, and a charge based on strips found after that date has no statute behind it.
Mandatory minimums in federal court are a separate system with its own weight tables; a case with any interstate element can end up there instead, and the exposure is often higher. See the FAQ for how a Miami-Dade case moves from arrest to first appearance.
At a glance
- Xylazine sale or possession with intent: first-degree felony, 3-year mandatory minimum, since October 1, 2026 (SB 432, Chapter 2026-148)
- Xylazine trafficking: 28 grams brings 3 years and $100,000; 100 grams brings 7 years and $100,000; 200 grams brings 25 years and $500,000
- Weight is the whole mixture, so a fentanyl bag cut with tranq can carry both trafficking counts
- Nitrous oxide at smoke shops, gas stations and convenience stores: third-degree felony since October 1, 2026 (Meg’s Law); grocery stores exempt
- Fentanyl and xylazine test strips: legal since July 1, 2026 (HB 477, Chapter 2026-157)
- Arrests before October 1, 2026 are charged under the old law
