Marijuana is consumed in more ways than ever, but the methods fall into a handful of core categories: inhalation (smoking and vaping), oral ingestion (edibles and capsules), sublingual absorption (tinctures and sprays), topical application (creams and patches), and less common routes like suppositories. Each method delivers cannabinoids to your body differently, which changes how quickly effects start, how intense they feel, and how long they last.
Smoking
Smoking remains the most traditional method. Ground cannabis flower, which averages just over 15% THC in samples tracked by the U.S. Drug Enforcement Agency, is rolled into joints, packed into glass or metal pipes, or loaded into water pipes (bongs). Combustion releases THC and other cannabinoids as smoke, which passes through the lungs and into the bloodstream almost immediately. Peak blood concentrations hit within about 10 minutes.
Bioavailability through inhalation ranges from 10% to 35%, meaning that’s the percentage of THC in the plant material that actually reaches your bloodstream. The wide range depends on how deeply you inhale, how long you hold each puff, and how many draws you take. Smoking produces a rapid, noticeable onset, and effects typically fade faster than with oral methods.
The obvious downside is combustion itself. Burning plant material creates tar and toxic particulates that irritate the airways, though the respiratory harm from cannabis smoke is generally considered less severe than from tobacco smoke.
Vaporizing
Vaporizers heat cannabis just enough to release cannabinoids as a vapor without burning the plant. This can be done with dry herb or with oil cartridges. The absorption profile is comparable to smoking: rapid onset within minutes, similar bioavailability of 10% to 35%, and a relatively short duration of effects.
Where vaping differs is in temperature control. Lower temperatures (around 320 to 350°F) tend to release lighter, flavor-forward terpenes like pinene and limonene. Mid-range temperatures (350 to 390°F) activate compounds like myrcene and linalool. Higher settings (390 to 430°F) extract heavier compounds but push closer to combustion temperatures. This control lets users tailor the experience in ways that smoking a joint simply doesn’t allow.
Vaporizing does reduce exposure to the toxic particulates found in smoke, though the reduction in measurable lung harm may be more modest than many users assume.
Concentrates and Dabbing
Concentrates are extracted cannabis products with dramatically higher THC levels than flower. Solvent-based concentrates like wax, shatter, and butane hash oil average 54% to 69% THC and can exceed 80%. Solventless options like rosin and bubble hash typically land between 39% and 60% THC. For comparison, standard flower averages around 15%.
Dabbing is the most common way to consume these concentrates. A small amount is placed on a heated surface (called a nail or banger), instantly vaporizing it for inhalation. The onset is just as fast as smoking or vaping flower, but the intensity is significantly higher because of the concentrated THC content. This method is not typically recommended for beginners.
Edibles
Edibles include gummies, chocolates, baked goods, capsules, and any food or drink infused with cannabinoids. When you swallow THC, it passes through your digestive system and into the liver before reaching your bloodstream. This process, called first-pass metabolism, converts THC into a different compound called 11-hydroxy-THC, which is itself psychoactive and crosses into the brain more readily than THC alone.
This liver processing is why edibles feel different from smoking. The body produces much higher concentrations of 11-hydroxy-THC after oral ingestion than after inhalation. Effects are often described as more intense, more body-centered, and longer lasting. But they also take much longer to arrive: peak THC blood levels after eating typically come 1 to 2 hours later, and in some cases can be delayed even further.
Oral bioavailability is low, only 4% to 12%, because the liver breaks down so much of the THC before it ever reaches circulation. This low and variable absorption is exactly why overconsumption is common with edibles. People eat a dose, feel nothing after 45 minutes, take more, and then both doses hit at once. Starting at 2.5 mg of THC or less is the standard guidance for anyone without an established tolerance. Even experienced users are generally advised to stay under 40 mg per day.
Cannabis Beverages and Nano-Emulsions
A newer category of edibles uses nano-emulsion technology to break THC into extremely small, water-compatible particles. These products, commonly sold as seltzers, drink mixes, and fast-acting gummies, bypass much of the liver’s first-pass metabolism. The result is a faster onset, typically 15 to 30 minutes compared to the 1 to 2 hours of a traditional edible. Many users report the effects also fade faster, making the experience feel closer to the timeline of a glass of alcohol than a standard gummy.
Sublingual Products
Tinctures, sprays, and lozenges designed to be held under the tongue or against the cheek absorb cannabinoids through the thin tissue lining your mouth, delivering them directly to the bloodstream without passing through the digestive tract first. CBD delivered this way through oil-based sprays or lozenges shows less variability in absorption compared to swallowed products, which makes dosing more predictable.
In practice, sublingual products sit somewhere between inhalation and edibles. Onset is faster than a standard edible because you’re skipping the stomach, but some portion of the tincture inevitably gets swallowed, so you often get a blended effect: a quicker initial onset followed by a slower, longer tail as the swallowed portion processes through the liver.
Topicals
Cannabis-infused creams, balms, and lotions are applied directly to the skin over sore muscles or inflamed joints. Cannabinoids are naturally poor at penetrating deep into skin. They tend to build up in the outermost layer, called the stratum corneum, and are generally thought not to reach the bloodstream. This means standard topicals provide localized effects without any high.
Transdermal patches are a different technology. These use specialized delivery systems with penetration enhancers and vasodilators designed to push cannabinoids through the skin and into systemic circulation. Recent pharmacokinetic research in humans has confirmed that both CBD and THC can successfully permeate through skin and enter the bloodstream using these advanced patch formulations. Transdermal patches offer slow, steady delivery over hours, which appeals to medical users looking for consistent relief without peaks and valleys.
Suppositories
Rectal suppositories are a niche but medically relevant route, used primarily in palliative care or for patients who can’t swallow. Onset is rapid, around 10 to 15 minutes, with peak effects occurring between 2 and 8 hours and total duration lasting up to 8 hours. This long, sustained action makes suppositories useful for overnight symptom management. They’re sometimes also used for gastrointestinal conditions or to help heal tissue damaged by radiation therapy.
How the Method Changes the Experience
The single biggest practical difference between consumption methods is timing. Inhalation peaks within 10 minutes and fades relatively quickly. Standard edibles peak at 1 to 2 hours and can last many hours. Nano-emulsion beverages land in between at 15 to 30 minutes. Sublingual products split the difference. Transdermal patches deliver a slow, flat curve over an extended period.
Intensity tracks with bioavailability and concentration. Dabbing a concentrate that’s 60% THC through the lungs, which absorb up to 35% of what’s inhaled, delivers a very different experience than eating a 5 mg gummy with 4% to 12% oral bioavailability. But edibles produce more 11-hydroxy-THC, which many people experience as a qualitatively different kind of high, not just a weaker one.
If you’re new to cannabis or trying a method for the first time, the universal principle is to start with a low dose and wait. For edibles specifically, that means 2.5 mg or less and at least two full hours before considering more. For inhalation, one small puff and a 15-minute pause gives you a reasonable read on how you’ll respond.
