Rick Simpson Oil in Florida: Legality, Dosage & Where to Find It

If you’ve spent any time on a Florida dispensary menu, you’ve probably noticed RSO tucked in with the concentrates. It’s a thick, dark extract that looks nothing like the polished vape carts and gummies around it. 

But that’s by design, because RSO is one of the oldest and most potent forms of medical cannabis. It’s built a loyal following among Florida patients dealing with serious symptoms. 

Here’s what you need to know about what it is, how it compares to other cannabis products, whether you can legally buy it here, and how to take it without overdoing it.

What Is RSO?

RSO stands for Rick Simpson Oil, named after the Canadian activist who developed it after using a homemade cannabis extract to manage his own health condition. 

He applied the extract directly to his skin, saw results within mere days, and began sharing his extraction method publicly, which is how RSO became a household name in medical cannabis circles and dispensaries nationwide. 

The oil itself is a full-spectrum extract, meaning it retains a wide range of the plant’s cannabinoids and terpenes rather than isolating just one. 

That’s why it looks the way it does: thick, dark brown to black, and sticky, closer in texture to molasses than to a typical vape oil. THC content commonly runs between 60% and 90%, making it one of the most concentrated products you’ll find on a Florida dispensary shelf.

RSO is popular specifically among people managing cancer symptoms, chronic pain, and severe insomnia, since its potency and long-lasting effects suit conditions that don’t respond well to lighter products. 

You’ll usually see it packaged in a marked oral syringe, meant to be taken by mouth or under the tongue rather than smoked or vaped.

RSO vs THC: What’s the Difference?

This is a common point of confusion, so it’s worth clearing up directly. THC is a single cannabinoid, the one responsible for cannabis’s psychoactive effects. 

RSO is not a separate substance from THC. It’s a full-spectrum oil that contains high levels of THC, alongside dozens of other cannabinoids, terpenes, and plant compounds.

Think of it this way: THC is one ingredient, and RSO is closer to the whole recipe. 

A standard THC distillate vape cart isolates THC almost completely, stripping out everything else for a clean, flavorless product. RSO keeps the full plant profile intact, which many patients say produces a heavier, more rounded effect. 

That difference is often chalked up to the entourage effect, the idea that cannabinoids and terpenes work better together than any one of them does alone.

RSO vs. CBD: What’s the Difference?

RSO and CBD oil are both cannabis extracts, but they’re very different and serve very different purposes. CBD oil is, per its name, high in cannabidiol (CBD) and formulated to contain little to no THC, so it won’t get you high. It’s widely available in Florida outside the medical program entirely, since hemp-derived CBD with under 0.3% THC is federally legal.

RSO is the opposite. It’s high in THC by design, and while it may contain some CBD depending on the cannabis strain used, THC is the dominant compound. 

If you’re looking for a non-intoxicating option to manage inflammation or mild anxiety, CBD oil is typically the better option.

RSO is for the ‘heavy duty’ use cases. When you want the stronger, longer-lasting effects that come with higher THC content, RSO is built for that job, but it typically requires a Florida medical card to access legally.

Is RSO Legal in Florida?

Yes, but only through the state’s medical marijuana program. Florida does not have a recreational cannabis market, so RSO and other high-THC products are restricted to registered patients. 

To buy it legally, you’ll need a qualifying medical condition, a recommendation from a physician registered with the state, and enrollment through the Office of Medical Marijuana Use.

Getting a card involves some upfront cost. Expect a $75 state application fee plus $150 to $250 for the required doctor’s evaluation, and you’ll need to renew every seven months. Veterans catch a break here: a 2026 law dropped the state fee to just $15 for qualifying veterans.

One more thing worth knowing before you buy: RSO’s high THC content will almost always show up on a standard drug test. 

Florida allows employers to maintain zero-tolerance drug policies even for registered medical patients, so it’s worth thinking through before you start using it if drug testing is part of your job.

Federally, cannabis remains a Schedule I substance, though a move to Schedule III has been expected and could shift things like banking access and research down the line. For now, Florida’s medical-only structure is what governs whether you can legally buy RSO for the most part.

Where to Buy RSO in Florida

Florida’s medical cannabis market runs through licensed Medical Marijuana Treatment Centers, commonly called MMTCs. Not every location carries RSO at all times, since it’s a lower-volume product compared to flower and vapes, so it helps to know which chains typically stock it.

Licensed Florida Dispensaries

• Trulieve: Trulieve has one of the largest dispensary footprints in Florida and regularly carries 1-gram RSO syringes for pickup or delivery. Its size makes it one of the more reliably stocked options if you’re searching statewide.
• MÜV: MÜV carries RSO cannabis syringes across its Florida locations, making it a solid option specifically for patients looking for a traditional RSO product rather than a newer concentrate format.
• Curaleaf: Curaleaf’s Florida menu includes 1-gram, high-THC, high-terpene hybrid RSO syringes, giving you a strain-specific option if you want to match the oil to a particular effect profile.
• The Flowery: The Flowery also stocks 1-gram RSO syringes for medical patients, rounding out a solid list of chains to check when you’re comparing potency and price.

Prices for RSO in Florida typically run $25 to $75 per gram, depending on the brand, THC percentage, and which dispensary you’re buying from. Since Florida’s market is medical-only, prices skew a bit higher than what you’d see in a state with recreational sales. 

If you want to compare full-spectrum options side by side before you buy, some RSO brands publish detailed potency and sourcing information online, which can help you figure out what you’re looking for before you get to the counter.

How to Take RSO Safely

RSO is not a product to guess your way through. Because it’s so concentrated, a small amount goes a long way, and taking too much too fast is the most common mistake first-time users make.

Start with an amount about the size of a half grain of rice, roughly 5mg of THC. Take it orally or place it under your tongue, and then wait. Effects from an oral dose typically take one to two hours to fully kick in, sometimes longer if you’ve eaten recently. Resist the urge to take more just because you don’t feel anything right away.

Once you understand how your body responds, you can slowly increase your dose under guidance from your physician. Some patients following long-term protocols eventually work up to much higher daily amounts over the course of weeks, but that level isn’t necessary or appropriate for everyone, and it should always be done with medical oversight rather than trial and error at home.

The Bottom Line

RSO is one of the most potent, full-spectrum options available in Florida’s medical cannabis market, and it’s earned its reputation among patients managing serious symptoms. It’s fully legal here, but only within the state’s medical program, so a qualifying condition and a registered physician’s recommendation are non-negotiable steps before you can buy it. Once you’re set up, real dispensary chains like Trulieve, MÜV, Curaleaf, and The Flowery make it straightforward to find.

If you’re new to RSO, start small, respect the wait time between doses, and lean on your physician to help you build a plan that fits your situation.
