A hemp cigarette is a smokable product filled with dried hemp flower instead of tobacco. It contains CBD (typically 50 to 90 mg per cigarette) and only trace amounts of THC, the compound responsible for marijuana’s high. Hemp cigarettes look nearly identical to traditional cigarettes, come in standard packs, and are designed to be smoked the same way, but they contain no tobacco and no nicotine.
What’s Inside a Hemp Cigarette
The core ingredient is dried hemp flower, sometimes called CBD flower. Some brands use only the flower buds, carefully removing stems and seeds, while others incorporate a broader mix of aerial plant parts including stalks, stems, and leaves. The difference matters: flower-heavy blends tend to deliver more CBD per cigarette and a smoother smoking experience, while whole-plant blends are typically less potent.
Beyond the hemp itself, what surrounds it varies. Some manufacturers use unbleached, biodegradable rolling paper and filters, while others use conventional rolling paper and standard cellulose acetate filters, the same synthetic plastic-like material found in regular cigarettes. A few brands also blend in other herbs alongside the hemp flower. The rolling paper, filter type, and any additives actually have a greater impact on your exposure to harmful byproducts than the hemp variety itself.
How Hemp Cigarettes Differ From Tobacco
The most significant difference is that hemp cigarettes contain no nicotine, which means they are not physically addictive in the way tobacco cigarettes are. Tobacco smoke contains roughly 5,000 different chemical compounds, with 44 confirmed to be genotoxic or cytotoxic, including tobacco-specific nitrosamines, formaldehyde, and benzene. Hemp cigarettes avoid the nicotine and tobacco-specific nitrosamines entirely.
That said, burning any plant material produces harmful byproducts. Research on herbal and cannabis smoke shows that compounds like carbon monoxide, tar, and aromatic amines are still present. In some cases, carbon monoxide and certain carcinogenic compounds have been measured at levels equal to or even higher than tobacco smoke. The absence of nicotine removes the addiction risk, but combustion itself remains a health concern regardless of what’s being burned.
How They Differ From Marijuana
Hemp and marijuana are both cannabis plants, but they are legally and chemically distinct. Under U.S. federal law, hemp must contain 0.3% THC or less on a dry weight basis. Anything above that threshold is classified as a controlled substance. A typical hemp cigarette contains far too little THC to produce intoxication. Instead, the dominant cannabinoid is CBD, which does not cause a high but is associated with calming and anti-inflammatory effects.
The smell and taste of hemp cigarettes are noticeably similar to marijuana, though. Both contain the same terpenes, the aromatic compounds responsible for cannabis’s distinctive scent. Common terpenes in hemp flower include myrcene (earthy, musky), limonene (citrusy), beta-caryophyllene (spicy, peppery), and pinene (fresh, pine-like). The overall aroma is herbaceous and distinctly “cannabis,” which can draw unwanted attention in public even though the product is legal.
CBD Delivery Through Smoking
One reason people choose hemp cigarettes over CBD oils or edibles is speed. Inhaling CBD delivers it to the bloodstream through the lungs almost immediately, with effects typically felt within minutes. The bioavailability of inhaled CBD ranges from 11% to 45%, with an average around 31%. By comparison, swallowing CBD in an oil or edible yields only about 6% bioavailability, meaning your body absorbs roughly five times more CBD from smoking than from eating the same amount.
A single hemp cigarette contains about 50 to 90 mg of CBD depending on the brand and blend, though how much you actually absorb depends on how deeply you inhale and how much of the cigarette you smoke.
Drug Testing Risks
This is where hemp cigarettes can cause real problems. Even though hemp is legal and contains very little THC, smoking it can trigger a positive result on a standard urine drug test. In a Johns Hopkins Medicine study, participants vaped less than 1 gram of cannabis containing 0.39% THC (just barely above the federal hemp limit of 0.3%), and two out of six tested positive using the same screening methods employers and courts commonly use.
The risk increases with repeated use. THC and its metabolites accumulate in the body over time, so daily hemp cigarette smokers face a higher chance of testing positive than someone who tries one once. Adding to the concern, a previous study found that 21% of CBD and hemp products sold online contained THC that wasn’t listed on the label. If you’re subject to drug testing for work, probation, or school, hemp cigarettes carry a real and documented risk of a positive result.
Using Hemp Cigarettes to Quit Tobacco
Some people turn to hemp cigarettes as a way to break a tobacco habit. The logic is straightforward: much of cigarette addiction is tied to the physical ritual of smoking, the hand-to-mouth motion, the inhale and exhale, the smoke breaks. Hemp cigarettes replicate that entire routine without delivering nicotine. For smokers whose cravings are partly behavioral, having something to smoke during high-stress moments or after meals can ease the transition away from tobacco.
CBD itself may also play a supporting role, as it has been linked to reduced anxiety and stress, both of which are common triggers for tobacco cravings. However, hemp cigarettes are not an FDA-approved smoking cessation tool, and no large clinical trials have tested their effectiveness for quitting tobacco. They eliminate nicotine from the equation but still expose your lungs to combustion byproducts.
Legal Status
Hemp cigarettes are federally legal in the United States under the 2018 Farm Bill, which removed hemp (defined as cannabis with 0.3% THC or less) from the list of controlled substances. Federal legality does not mean they’re legal everywhere you live, though. Individual states set their own rules on smokable hemp products, and some have moved to restrict or ban them outright.
Alabama, for example, banned smokable hemp products starting July 1, 2025. Other states have imposed various restrictions on sales, packaging, or where smokable hemp can be sold. Before buying or traveling with hemp cigarettes, it’s worth checking your state’s current regulations, as the legal landscape is shifting quickly and varies significantly from one state to the next.
