DENIS CHARLET | AFP via Getty Images Share on Twitter Share on Facebook Share on Pocket Florida smoke shops, vape shops, and other tobacco-licensed retailers can no longer sell nitrous oxide as of Oct. 1, when Meg’s Law took effect. The measure is part of CS/SB 432, which also creates a new crime of trafficking in xylazine, an animal sedative increasingly found in the illegal fentanyl supply.

The law is named for Margaret “Meg” Caldwell, 29, of Clermont. Her body was found in November 2024 behind an Orange County smoke shop where she had bought nitrous oxide products, NBC News reported. Her family says she died as a result of her addiction to the gas. Because the products were sold openly in stores, her sisters said she believed they were safe. “She would tell us, I’m buying this legally. I’m not doing anything wrong with this,” her sister Kathleen Dial told NBC. Another sister, Leigh Caldwell, said a doctor had warned Meg she could die if she kept using it.

“We’re glad to see Meg have a legacy, something positive that she leaves behind on this earth that hopefully will help other families from suffering the same fate that our family has suffered,” Dial told WLRN. For parents of teens and young adults, the law targets brightly packaged, flavored canisters sold at the same counters as vapes, products many young buyers assume are harmless because they are legal.

Under the law, it is a third-degree felony for a tobacco or nicotine dealer licensed under Chapter 569 of Florida law to possess, sell, deliver, or give away nitrous oxide on or from its licensed premises. The ban covers convenience stores but does not apply to grocery stores or supermarkets. Finished food products that use the gas only as a propellant, such as canned whipped cream, are also exempt.

The law does not ban all possession. Florida already makes it a third-degree felony to knowingly distribute, sell, buy, transfer, or possess more than 16 grams of nitrous oxide. Gov. Ron DeSantis signed the bill on June 16 as Chapter 2026-148, and lawmakers presented it to Caldwell’s family at a ceremony in Lake County in July. The bill passed both chambers without a single no vote.

Enforcement details are still pending. The law directs the Florida Department of Business and Professional Regulation to adopt rules on the possession, sale, and distribution of nitrous oxide, and no timeline for those rules has been announced.

Sen. Clay Yarborough, the bill’s sponsor, said earlier this year that “Nitrous oxide has legitimate culinary and medical uses, but small- and large-format canisters are increasingly being marketed with bright packaging and flavoring and sold at vape shops and convenience stores,” FOX 13 reported.

The FDA advises consumers not to inhale nitrous oxide products, warning that they “can result in serious adverse health effects, including death.” Brands named by the agency include Galaxy Gas, Cloud 9ine, and Whip-it!.

Listed harms include loss of consciousness, asphyxiation, vitamin B12 deficiency, and paralysis. Repeated use disrupts vitamin B12, which nerves need to work properly. A CDC report on recreational nitrous oxide misuse explains that chronic long-term use “can cause disabling neurologic sequelae, including neuronal demyelination and subacute combined spinal cord degeneration,” meaning damage to the protective coating of nerves and to the spinal cord.

The same report tracked emergency department visits in Michigan from 2019 to 2023. Visits tied to nitrous oxide rose 757%, from 7 to 60, and most patients were ages 20 to 39. A study published in JAMA Network Open in July 2025 counted 156 U.S. deaths linked to nitrous oxide in 2023, up from 23 in 2010.

Warning signs that need medical attention include numbness or tingling in the hands or feet, weakness, balance problems, and confusion. Fainting, trouble breathing, or chest pain after use requires emergency care. Nerve damage caught early may improve with treatment, so people who use the gas regularly should tell a clinician even if symptoms seem mild.

The law makes selling or distributing xylazine for human consumption a first-degree felony with a three-year mandatory minimum sentence. New trafficking tiers start at 28 grams, with a three-year minimum sentence and a $50,000 fine, and rise to 25 years and $500,000 for 200 grams or more. FDA-approved veterinary products are exempt. The provision exempting those products from Florida’s drug schedules took effect July 1, while the trafficking penalties began Oct. 1.

The CDC notes that xylazine is not approved for use in people and can cause dangerous sedation, slowed breathing, and wounds that can become infected. “Naloxone will not reverse the effects of xylazine,” the agency says, but it still urges people to give naloxone during a suspected overdose because xylazine is usually mixed with opioids.

Florida’s latest Medical Examiners Commission drug report found that xylazine occurrences fell 17% in 2024, to 458, while deaths caused by xylazine fell 2%. The Caldwell family’s lawsuit against smoke shops and nitrous oxide makers is a separate case, and its current status has not been publicly updated.

What does Meg’s Law ban? It makes it a felony for tobacco- and nicotine-licensed retailers, including smoke and vape shops, to sell, give away, or possess nitrous oxide on their premises.

Can I still buy whipped cream in Florida? Yes. Food products that use nitrous oxide only as a propellant are exempt, and grocery stores are not covered.

Who was Meg? Meg Caldwell was a 29-year-old Clermont woman whose family says she died from nitrous oxide addiction in 2024.

What are the health risks of inhaling nitrous oxide? The FDA warns of loss of consciousness, suffocation, vitamin B12 deficiency, nerve damage, paralysis, and death.

What changed for xylazine? Florida created a trafficking crime starting at 28 grams, with mandatory prison terms and fines up to $500,000.

Who enforces the nitrous oxide rules? The Florida Department of Business and Professional Regulation must write rules, which are still pending.
