Short answer: No. SBX vapes contain zero milligrams of nicotine not tobacco-derived, not synthetic. Instead, the SBX 25K uses 5% Metatine, a lab-made nicotine analog that mimics nicotine’s effects while legally not being nicotine. That single distinction explains the product’s popularity, its marketing, and the regulatory fights around it. Here’s the full picture, without the hype.

What Is Metatine?
Metatine is the brand name for 6-methylnicotine (6-MN), a synthetic molecule developed and patented by Charlie’s Holdings (the company behind SBX and Charlie’s Chalk Dust e-liquids). Chemically, it’s nicotine with an extra methyl group attached close enough to bind to the same nicotinic receptors in the brain, different enough to not be classified as nicotine under current federal law.
Key facts:
- Not from tobacco. Company filings state SBX liquid is not made from or derived from tobacco and contains no nicotine from any source.
- Synthetic. It’s manufactured in a lab, not extracted from plants.
- 5% strength. The SBX 25K lists 5% Metatine the same percentage number you’d see on a 5% nicotine disposable, which is exactly why buyers get confused.
- No THC, no CBD. It’s a nicotine alternative only.
Metatine vs Nicotine: What’s Actually Different?
| Nicotine | Metatine (6-MN) | |
|---|---|---|
| Chemical identity | Nicotine | 6-methylnicotine one methyl group different |
| Source | Tobacco plant or synthetic | Lab-synthesized, never from tobacco |
| Strength in SBX | 0 mg none present | 5% (50 mg/mL equivalent labeling) |
| How it works | Binds nicotinic acetylcholine receptors | Binds the same receptors |
| Throat hit / buzz | The familiar nicotine sensation | Users report a very similar buzz, often described as smoother |
| Addictive potential | Yes, well documented | Unknown precisely but it acts on the same receptors, so dependence is plausible |
| Federal tobacco regulation | Regulated as tobacco product, PMTA required | Company claims exemption (“PMTA-exempt”) |
The honest version: Metatine is nicotine’s close chemical cousin. It feels similar because it does a similar job in the brain. “Nicotine-free” is legally accurate and chemically accurate but it doesn’t mean effect-free.
Does It Feel the Same as Nicotine?
According to user reports across retail reviews and Reddit discussions, most vapers describe the SBX experience as very close to a standard 5% nicotine disposable satisfying throat hit, familiar buzz, no harshness. Some note it feels slightly smoother or “cleaner” than nicotine salts.
But here’s what nobody selling it will tell you: the research base is thin. Early toxicology literature and agency statements suggest some nicotine analogs, including 6-MN, may be more potent than nicotine itself meaning the same percentage could hit harder. The science is still evolving, and there are no long-term studies on inhaling 6-methylnicotine. Treat confident safety claims from sellers with skepticism.
Is Metatine Addictive?
There is no clinical addiction study on Metatine specifically. What we know:
- It binds the same nicotinic receptors as nicotine.
- Substances that activate those receptors tend to carry dependence risk.
- Users report nicotine-like satisfaction and cravings patterns.
The reasonable assumption: it likely carries a dependence risk similar to nicotine, even though it isn’t nicotine. If you’re using SBX to step away from nicotine entirely, understand you’re swapping one receptor-activating compound for a less-studied cousin not stepping off.
Is SBX Vape Safe? Side Effects
Straight talk: nobody can give you a definitive safety verdict on Metatine yet. Here’s what’s known and not known:
Reported by users: throat irritation (mild), dizziness if chain-vaped, nausea at high intake the same complaints you’d hear about strong nicotine disposables.
What science says: very little. No long-term inhalation studies exist for 6-methylnicotine. Early signals suggest it may be more pharmacologically potent than nicotine, which cuts both ways similar satisfaction, but unknown toxicology.
Bottom line: “nicotine-free” does not mean “risk-free.” If you don’t vape, don’t start with SBX either. This isn’t a wellness product it’s a recreational vape with a novel active ingredient and a short research history.
Legal Status: The Loophole (and Where It’s Closing)
This is where SBX gets interesting and where most competitor articles go vague.
Federal level: Because Metatine isn’t nicotine and isn’t tobacco-derived, Charlie’s Holdings argues SBX falls outside the FDA’s tobacco product authority marketed as “PMTA-exempt.” The FDA has not granted SBX any marketing authorization (check our FDA authorized vapes list it’s not on it, and no flavored disposable is). Whether the FDA agrees with the exemption claim long-term is an open question.
States are catching up:
- California: AB 3218 / SB 1230 (effective 2025) expanded state definitions to include nicotine analogs the Metatine loophole is closed there.
- New York: A December 2024 health department communication indicated flavored vapes with non-nicotine ingredients like 6-MN are not prohibited by the state’s flavor ban but New York City’s separate law still bans all flavored e-cigarettes except tobacco/unflavored.
- New Jersey: bans flavored vapor products regardless of whether they contain nicotine Metatine doesn’t help there.
The trend is clear: the “not technically nicotine” defense works in some jurisdictions today, but lawmakers are writing analogs into new laws. Don’t assume today’s legal status is permanent.
FAQs
Does SBX vape have nicotine?
No. SBX contains 0mg nicotine. It uses 5% Metatine (6-methylnicotine), a synthetic nicotine analog.
What is in SBX vape?
The e-liquid contains Metatine (6-MN), propylene glycol, vegetable glycerin, and flavorings. No nicotine, no THC, no CBD, no tobacco derivatives per the manufacturer’s filings.
Does SBX vape have THC?
No. SBX is a Metatine vape, not a cannabis product. It contains no THC or CBD.
Is SBX vape FDA approved?
No. SBX has no FDA marketing authorization. The company claims it’s exempt from FDA tobacco premarket review because it contains no nicotine a claim regulators may test.
How much nicotine is in SBX 5%?
Careful: the label says 5% Metatine, not 5% nicotine. The percentage looks familiar, but the compound is different.
Can SBX help me quit nicotine?
There’s no evidence for that, and it’s not a cessation product. You’re replacing nicotine with a less-studied analog that acts on the same receptors.
Will Metatine show up on a nicotine drug test?
Standard nicotine tests look for cotinine, nicotine’s metabolite. Metatine is chemically distinct, so it may not trigger those tests but cross-reactivity is possible and this hasn’t been verified. Don’t rely on it.
Is SBX vape safe?
Unknown. No long-term studies exist on inhaling 6-methylnicotine, and early research suggests it may be more potent than nicotine. Nicotine-free doesn’t mean risk-free.
