Standard cigars do not contain THC. A traditional cigar is made entirely from tobacco, and tobacco plants do not produce THC. The active compound in cigars is nicotine, along with a handful of other tobacco-specific alkaloids. If you’ve seen references to cigars and THC in the same sentence, it almost certainly involves one of two things: blunts (cigars hollowed out and refilled with marijuana) or hemp cigars, a newer product category. Here’s how to sort it all out.
What’s Actually in a Regular Cigar
Cigars are rolls of tobacco wrapped in tobacco leaf. The FDA defines a cigar specifically as a tobacco product, and the key psychoactive ingredient is nicotine. Commercial tobacco products contain nicotine at concentrations of roughly 6.5 to 17.5 milligrams per gram, along with minor alkaloids like nornicotine, anabasine, and anatabine. These compounds are unique to the tobacco plant and have nothing chemically in common with THC.
Nicotine and THC work on completely different systems in the brain. Nicotine activates receptors in the brain’s cholinergic system, which influences alertness, mood, and attention. THC binds to cannabinoid receptors (CB1), which are part of the endocannabinoid system and produce the “high” associated with marijuana. There is some overlap in the brain’s reward circuits between these two systems, which is one reason people sometimes use both substances together, but the compounds themselves are distinct.
Why Cigars and THC Get Linked: Blunts
The most common reason people associate cigars with THC is the practice of making blunts. A blunt is a small cigar or cigarillo that’s been split open, emptied of most of its tobacco, and refilled with cannabis. The cigar wrapper, which is made from tobacco leaf, becomes the rolling material. The THC comes entirely from the marijuana stuffed inside, not from the cigar itself.
This distinction matters more than you might think. Because the tobacco wrapper remains, blunt smokers get exposure to both THC and nicotine at the same time. Residual tobacco left inside the wrapper adds to that nicotine dose, and research has found that blunt users are more likely to develop nicotine dependence compared to people who smoke cannabis in other forms. Interestingly, joints (cannabis rolled in plain paper without any tobacco) actually deliver more THC to the bloodstream and produce stronger subjective effects than blunts, particularly in women. The tobacco wrap appears to reduce how much THC you absorb per hit.
Hemp Cigars and Cannagars
A newer product category does blur the line between cigars and cannabinoids. Hemp cigars are made from hemp flower rather than tobacco, and they can contain CBD along with trace amounts of THC. Under the 2018 Farm Bill, hemp products are federally legal in the United States as long as they contain less than 0.3% delta-9 THC by dry weight. That’s a very small amount, far below what would produce any noticeable psychoactive effect.
Then there are cannagars, which are essentially cannabis cigars sold through licensed dispensaries in states where recreational or medical marijuana is legal. These are a completely different product from anything you’d find at a gas station or tobacco shop. In California, for example, a non-edible cannabis product for the adult-use market can contain up to 1,000 milligrams of THC per package, and labels must list the exact THC and CBD content in milligrams. These products go through state-regulated testing and labeling requirements, and they are only available where state law permits cannabis sales.
So while a hemp cigar from a smoke shop will have negligible THC, a cannagar from a dispensary can contain a substantial dose. The packaging and point of sale make them easy to tell apart if you know what to look for.
How to Tell What You’re Buying
If you pick up a cigar at a convenience store, tobacco shop, or liquor store, it contains tobacco and zero THC. These products are regulated by the FDA as tobacco products and cannot legally contain cannabis.
Hemp cigars, often sold online or in CBD shops, will be labeled as hemp and must stay under the 0.3% THC threshold to be sold legally at the federal level. They won’t get you high, though they may contain meaningful amounts of CBD.
Cannagars or THC-infused cigars are only available at licensed cannabis dispensaries in states with legal marijuana markets. They will always list their THC content on the label, and they cost significantly more than a tobacco cigar. If someone hands you something that looks like a cigar but came from a dispensary, it very likely contains THC, and the label will tell you exactly how much.
The short answer: a cigar, by definition, is a tobacco product with no THC. But the word “cigar” gets borrowed by cannabis culture in ways that can create real confusion, especially if you’re not familiar with the differences between a Swisher Sweet from a gas station, a hemp wrap from a CBD shop, and a cannagar from a dispensary.
