CBD cigarettes are smokable products that use hemp biomass instead of traditional tobacco, offering an alternative method for consuming cannabidiol. Their popularity is driven by consumer interest in the effects of CBD delivered through the familiar ritual of smoking. This consumption method allows for the rapid inhalation of hemp compounds, making it a distinct choice within the broader market of CBD products.
Composition and Differentiation
CBD cigarettes are composed of dried, cured hemp flower, a strain of the Cannabis sativa plant cultivated to contain high levels of cannabidiol. A defining characteristic is the absence of tobacco and the addictive substance nicotine, setting them apart from conventional cigarettes. Manufacturers ensure the product is rolled using only the hemp plant material, sometimes with a filter similar to a tobacco cigarette.
The fundamental legal distinction from marijuana is the tetrahydrocannabinol (THC) content. For a product to be legally classified as industrial hemp, its delta-9 THC concentration must not exceed 0.3% on a dry weight basis. This trace amount of THC is insufficient to produce the psychoactive effects or “high” associated with marijuana.
Beyond CBD, the hemp flower contains other naturally occurring compounds, including minor cannabinoids and fragrant molecules called terpenes. Terpenes give the plant its distinctive aroma and flavor and are believed to interact synergistically with the cannabinoids. This combination of compounds contributes to a wider range of effects, often referred to as the “entourage effect,” compared to using isolated CBD.
How CBD Affects the Body
Once inhaled, cannabidiol rapidly enters the bloodstream, where it interacts with the body’s vast regulatory network known as the Endocannabinoid System (ECS). The ECS helps maintain internal balance, or homeostasis, by regulating functions like mood, pain, sleep, and immune response. The system is composed of endocannabinoids produced by the body, cannabinoid receptors (CB1 and CB2), and metabolic enzymes.
CBD does not directly bind to CB1 and CB2 receptors in the way that THC does to cause intoxication. Instead, it interacts indirectly, acting on non-cannabinoid receptors and modulating the activity of the ECS. A primary mechanism involves inhibiting the enzyme fatty acid amide hydrolase (FAAH), which breaks down the body’s own endocannabinoid, anandamide.
By slowing the breakdown of anandamide, CBD allows this naturally occurring compound to remain in the system longer, enhancing its ability to signal to receptors. This indirect action allows cannabidiol to influence the ECS without generating a euphoric sensation. The molecule is considered non-intoxicating and non-impairing, supporting the body’s natural processes of balance.
Health Considerations of Combustion
Despite the absence of nicotine, smoking CBD hemp flower introduces significant health considerations due to the combustion process itself. Burning any plant material, including hemp, generates chemical byproducts and particulate matter that are inhaled directly into the lungs. This smoke contains carcinogens, carbon monoxide, and irritants like hydrogen cyanide and ammonia.
The combustion process produces fine particulate matter (PM2.5) and tar, which can accumulate in the lungs and bronchial passages. Regular inhalation of these substances can lead to irritation, coughing, and increased phlegm production, and is associated with chronic bronchitis and airflow obstruction. The fundamental respiratory risks associated with inhaling smoke remain, even though hemp smoke may lack some of the harmful additives found in processed tobacco.
The rapid onset of effects achieved by smoking is due to the compounds bypassing the digestive system and liver, traveling directly from the lungs into the bloodstream. However, this route exposes delicate lung tissues to toxic substances created by the heat and burning material. Regardless of the properties of the CBD molecule itself, the delivery method of combustion carries inherent risks to the respiratory system. Research indicates that cannabis smoke contains several toxic chemicals, such as acrylonitrile and acrylamide, that are found in lower concentrations than in tobacco smoke but are still present.
Regulatory Status and Consumer Access
The legal status of CBD cigarettes stems from the 2018 Farm Bill, which federally legalized hemp by defining it as Cannabis sativa with less than 0.3% delta-9 THC. This legislation removed hemp from the federal Controlled Substances Act, allowing for its cultivation and the interstate commerce of its derivatives. However, the federal legalization of the plant did not automatically legalize all resulting products.
The Food and Drug Administration (FDA) retained its authority to regulate products containing cannabis and cannabis-derived compounds. The FDA has not approved CBD for use in any inhaled products, and it monitors companies making unproven health claims. Introducing CBD into interstate commerce as a food additive or a dietary supplement is currently considered unlawful by the agency.
The result is a complicated regulatory patchwork where the federal definition of hemp allows for CBD cigarettes, but state and local jurisdictions can impose their own restrictions. Consumers may encounter age restrictions similar to those for tobacco, and public consumption of smokable hemp is often restricted or banned in places where smoking is prohibited. This variability means that legality and purchasing access can change significantly from one state or municipality to the next.
