Marijuana is used in several distinct ways, and the method you choose changes how quickly it takes effect, how intense the experience feels, and how long it lasts. Smoking dried flower remains the most common method in the United States and Canada, but edibles, vaporizers, concentrates, topicals, and newer delivery systems like transdermal patches have all grown in popularity, especially in states where recreational use is legal.
Smoking
The most traditional method is smoking dried cannabis flower in a joint (rolled in paper), a pipe, a bong (water pipe), or a blunt (rolled in a tobacco leaf wrap). When you inhale smoke, THC passes through the lungs and enters the bloodstream almost immediately, reaching peak levels in the brain within 6 to 10 minutes. The bioavailability of inhaled THC ranges from 10% to 35%, meaning that’s the fraction of THC in the plant material that actually makes it into your system. The rest is lost to combustion, sidestream smoke, and exhaled vapor.
Effects typically last one to three hours, though some residual feeling can linger longer. Because THC concentrations in the brain are higher than in the blood after inhalation, smoking generally produces a stronger psychoactive effect per milligram of THC than eating the same amount.
The main downside is combustion. Burning plant material produces tar, carbon monoxide, and other irritants that can affect lung health over time, similar to tobacco smoke.
Vaporizing
Vaporizers heat cannabis flower or oil to a temperature high enough to release THC as a vapor but below the point of combustion. This eliminates most of the tar and toxic byproducts associated with smoking while preserving a similar onset and duration. Handheld “vape pens” that use pre-filled oil cartridges are the most popular format, though tabletop vaporizers designed for dried flower also exist.
The onset timeline mirrors smoking closely, with effects arriving within minutes. Some users report a slightly cleaner, less harsh sensation in the throat and lungs compared to smoking, which is the primary reason people switch to vaping.
Concentrates and Dabbing
Concentrates are extracted forms of cannabis that contain extraordinarily high THC levels, typically ranging from 40% to 80%. They go by many names: wax, shatter, budder, honey oil, and live resin, among others. “Dabbing” refers to the practice of heating a small amount of concentrate on a hot surface (usually a nail or electronic heating element) and inhaling the resulting vapor.
Because THC concentrations are several times higher than in dried flower (which generally ranges from 15% to 30%), dabbing delivers a much more intense effect in a single inhalation. This makes it easier to consume more THC than intended, particularly for people without a high tolerance. The onset is just as rapid as smoking or vaping.
Edibles
Edibles include gummies, chocolates, baked goods, beverages, and capsules that contain THC or CBD. This is where the body processes marijuana in a fundamentally different way. When you swallow THC, it travels to the liver before reaching the rest of your body. The liver converts much of it into a psychoactive metabolite that crosses into the brain more readily than THC itself, which is why many people describe edible highs as feeling more intense or “body-heavy” compared to smoking.
The trade-off is speed: edibles can take 30 minutes to 2 hours to kick in, depending on your metabolism, whether you’ve eaten recently, and the specific product. This delayed onset is the most common reason people accidentally take too much. They eat a dose, feel nothing after 45 minutes, eat more, and then both doses hit at once. In regulated markets, edible packages are capped at 10 mg of THC per package in some jurisdictions, and public health guidelines suggest starting at 2.5 mg or less if you’re new to edibles.
Bioavailability for ingested THC is only 4% to 12%, much lower than inhalation. But because the liver metabolite is potent in its own right, the subjective experience can still be powerful. Effects last considerably longer than smoking, often 4 to 8 hours, with some people reporting residual grogginess the next morning at higher doses.
Tinctures and Sublingual Products
Tinctures are liquid cannabis extracts, usually suspended in alcohol or oil, that come with a dropper. You place a few drops under the tongue and hold them there for 30 to 60 seconds before swallowing. The tissue under the tongue is thin and rich in blood vessels, so some THC absorbs directly into the bloodstream, bypassing the liver. This gives tinctures a faster onset than standard edibles, often 15 to 30 minutes, while still avoiding the lung exposure that comes with smoking.
Any portion you swallow follows the same liver pathway as an edible, so tinctures produce a hybrid effect: a quicker initial onset with a longer tail of effects from the swallowed portion.
Topicals and Transdermal Patches
Topicals are creams, balms, and lotions infused with cannabinoids that you apply directly to the skin. Most topicals do not produce a high because the cannabinoids stay in the local tissue and don’t reach the bloodstream in significant amounts. People use them primarily for localized muscle soreness or joint discomfort.
Transdermal patches work differently. They use specialized technology, including penetrating agents and compounds that widen tiny blood vessels in the skin, to push cannabinoids through the deeper layers and into the bloodstream. Early pharmacokinetic studies in humans have confirmed that both THC and CBD can enter systemic circulation this way, making patches one of the few skin-based methods that can produce body-wide effects. Patches deliver a slow, steady dose over several hours, which appeals to people who want consistent relief without the peaks and valleys of smoking or edibles.
Medical Uses
The FDA has approved one cannabis-derived medication, Epidiolex, a purified CBD product used to treat seizures in patients with Lennox-Gastaut syndrome or Dravet syndrome, both severe forms of epilepsy. Three synthetic THC-related drugs are also approved: two containing dronabinol (for chemotherapy-induced nausea and wasting syndrome in AIDS patients) and one containing nabilone (also for chemotherapy nausea). No whole-plant cannabis product has received FDA marketing approval.
State medical marijuana programs, which operate separately from FDA oversight, allow physicians to recommend cannabis for a broader set of conditions. Qualifying diagnoses vary by state but commonly include cancer, HIV/AIDS, ALS, Parkinson’s disease, multiple sclerosis, epilepsy, inflammatory bowel disease, neuropathies, Huntington’s disease, and complications like chronic pain, severe nausea, wasting syndrome, and persistent muscle spasms. In these programs, patients can access flower, edibles, tinctures, topicals, and other products through licensed dispensaries.
How Method Affects the Experience
The choice of consumption method is really a set of trade-offs across four variables: onset speed, duration, intensity, and health considerations.
- Fastest onset: Smoking, vaping, and dabbing (6 to 10 minutes to peak)
- Slowest onset: Edibles (30 minutes to 2 hours)
- Longest duration: Edibles and transdermal patches (4 to 8+ hours)
- Shortest duration: Smoking and vaping (1 to 3 hours)
- Highest intensity per dose: Concentrates and dabbing (40% to 80% THC)
- Lowest lung exposure: Edibles, tinctures, topicals, and patches
Your body weight, tolerance, metabolism, and even genetics all influence how you respond to any method. If you’re trying a new format, the general principle is to start with a low amount and wait long enough to feel the full effect before taking more. This is especially important with edibles, where the gap between ingestion and onset catches many people off guard.
