A Practical Guide to Vaping Cannabis: Devices, Technique and Safety

How vaporizers heat cannabis without burning it, how flower and oil vapes differ, what the 2019 outbreak taught about illicit carts, and where you can vape in Michigan.

Vaping cannabis means heating flower or concentrate until its active compounds turn into vapor, without setting the plant alight. You inhale that vapor instead of smoke. This guide covers how vaporizers work, how to use flower and oil devices, how vaping compares with smoking, what's known about safety, and where you can and can't vape in Michigan.

What a cannabis vaporizer is and how it works

A vaporizer is an electronic device with three basic parts: a power source (usually a battery), a heating element and a chamber or cartridge that holds the cannabis. Some are slim pens. Others are larger devices built for flower or for concentrates.

Heating without burning

Burning cannabis creates smoke, along with tar and other byproducts of combustion. A vaporizer works in a lower window: hot enough to release cannabinoids and terpenes, but short of the point where the plant burns. Researchers who tested dry-herb vaporizers set them to 210°C (410°F) and noted that the acid forms of cannabinoids convert to their active forms above roughly 180°C (356°F). Because nothing burns, the vapor avoids combustion products such as tar.

Lower settings tend to keep more of the flavor, since heat breaks terpenes down. Higher settings produce more vapor, and lab tests of oil pens have found more harmful byproducts at higher power. Many devices let you choose.

Vaping dry flower: devices and technique

Dry-herb vaporizers heat ground flower in a small oven. Conduction models heat it through contact with the hot chamber walls, while convection models pass heated air through it. Portable units fit in a pocket; tabletop models stay home.

A few habits make a real difference:

  1. Grind it medium-fine. Smaller pieces heat evenly, but powder can clog screens.
  2. Pack it evenly. Fill the chamber without crushing the flower tight, so heat and air can move through.
  3. Start low. Begin at a lower temperature and step up between sessions.
  4. Draw slowly. Long, gentle pulls work better than short, hard ones.
  5. Empty and brush the chamber. Spent flower turns light brown, a sign it's done.

Vaping concentrates: carts, pens and portable rigs

Cartridges. Prefilled carts hold cannabis oil, such as distillate, live resin or rosin, and screw onto a battery. They're the simplest way to start, and our vape pen guide explains the parts.

Disposables. An all-in-one pen with the battery and oil built in. You use it until the oil or the battery runs out.

Portable rigs. Pocket-size electronic rigs heat a small bowl of wax, badder or rosin at set temperatures, much like a home dab rig without the torch.

Oil pen or dab pen? How the two devices differ

A vape pen vs. dab pen comparison starts with what goes inside. An oil pen uses a sealed, prefilled cartridge of liquid oil: you attach it and draw. A dab pen has an open chamber with a coil or ceramic plate that you load yourself with solid concentrates such as wax or shatter. Our dab pen explainer covers loading and care.

People comparing a dry herb vape vs. a cart are really choosing between flower and oil: many people find flower vaporizers taste closest to the plant, while carts are quicker to use.

Vaping cannabis vs. smoking

That last row surprises people. When researchers gave healthy adults who rarely used cannabis equal doses of THC, the vaporized dose produced stronger drug effects and higher peak blood THC levels than the smoked one. If you switch from joints to a vaporizer, take smaller draws at first.

Why people choose vaping

  • Discretion. Less odor and more discretion rank among the top reasons people give for vaping, though vapor is never odorless.
  • Ease. A pen needs no rolling and no lighter.
  • Efficiency and cost. A flower vaporizer can be paused mid-session, so many people find their flower goes further.
  • Dose control. One short draw at a time is easier to pace than a whole joint.
  • Taste. Many users say vapor tastes better than smoke.
  • Portability. Pens and small vaporizers fit in a pocket or bag, though where you may use them is limited.

Safety: what's known, and what the 2019 outbreak taught

No way of inhaling cannabis is harmless. Vaping avoids the toxic byproducts of burning, but heated cartridge oils can still form harmful compounds, and the CDC notes that vaping cannabis has led to lung injury and even death. A 2021 review found no randomized trials or cohort studies of its effects on breathing, and its long-term effects on the heart remain unclear. Is vaping safer than smoking? It avoids some harms of combustion, and that's as far as the evidence goes.

The clearest lesson came in 2019, when a wave of serious lung injuries, called EVALI, put people in hospitals in every state. By February 2020, the CDC had counted 2,807 hospitalized cases or deaths. The agency found that vitamin E acetate, an additive used most notably in THC vaping products, was strongly linked to the outbreak. It also found that THC products from informal sources, such as friends, family or dealers, were linked to most cases.

At the time, the CDC and FDA advised people not to use THC vaping products, particularly from informal sources, and not to add anything to a vape. The CDC also says vaping products should never be used by young people or by anyone who is pregnant. What that means for you:

  • Buy vapes only from licensed retailers. Every licensed product in Michigan carries a label that names its testing lab.
  • Never modify a cartridge, refill a disposable or add anything to the oil.
  • If you have breathing trouble or chest pain after vaping, stop and get medical care.
  • Talk to your doctor before vaping if you have a heart or lung condition.

Our THC vape buying guide explains how to read a cart's label before you buy.

Cleaning and caring for a vaporizer

Dry-herb vaporizers. Brush out the chamber after each session. Every so often, take apart the removable pieces, such as the mouthpiece, screens and seals, and wipe or soak them in isopropyl alcohol. Let everything dry completely before you reassemble it, and keep liquids away from the battery.

Cartridges and batteries. Store carts upright at room temperature, out of hot cars and direct sun. If the connection gets sticky, wipe the threads on the battery and the cart with a dry cotton swab. Charge the battery with the charger made for it.

Dab pens. Clean the coil or plate gently with a cotton swab, following the maker's directions, and replace coils when the flavor turns burnt.

Clogs and leaks are the most common cart problems. Our guide to vape care walks through the fixes.

Where you can vape in Michigan

Michigan law allows adults 21 and older to use cannabis, but not anywhere they like, and vaping counts as use.

  • No public use. Using cannabis in a public place is not allowed, and property owners may ban smoking or use on their property.
  • Not behind the wheel. No one may use cannabis while driving or in control of a car, boat, snowmobile, off-road vehicle or aircraft, and driving while under the influence is against the law.
  • Not at schools. Cannabis and accessories aren't allowed on the grounds of preschool through 12th-grade schools, on school buses or at correctional facilities.
  • Workplaces. Employers don't have to allow cannabis at work and may enforce their drug policies.

Frequently asked questions

Is vaping cannabis safer than smoking?

Different, not harmless. Vaporizers heat cannabis without burning it, so you avoid the tar and other byproducts of smoke. But inhaling any cannabis product carries risk, the long-term effects of vaping are still being studied, and illicit carts have caused serious lung injuries. If you vape, choose licensed, tested products and never modify them.

Does vaping get you higher than smoking?

It can. In a lab study of adults who rarely used cannabis, equal doses of THC produced stronger effects and higher peak blood THC levels when vaporized than when smoked. If you're switching from joints, take less than you're used to and wait between draws.

How do you use a vape pen for the first time?

Charge the battery, then screw the cartridge on gently until it's snug, not tight. If the pen has a button, follow the instructions to switch it on. Take one slow, short draw of two or three seconds, then wait and notice how you feel before you take another; inhaled cannabis can take up to 30 minutes to reach full effect. Store the pen upright between uses.

How do you clean a dry-herb vaporizer?

Brush out the chamber after every session once it has cooled. Every week or two, depending on use, remove the mouthpiece, screens and seals, then wipe or soak them in isopropyl alcohol and let them dry completely. Keep liquids away from the battery, and follow the maker's directions for your model.

Can you vape in public in Michigan?

No. Michigan law doesn't allow cannabis use in a public place, and vaping counts. Property owners may also ban smoking or use on their property, and you can't use cannabis while driving or in control of a vehicle. Enjoy it at home or on private property where it's allowed, and never drive high.
