Vaporizing Cannabis
Vaporizing heats cannabis below combustion temperature, releasing cannabinoids and terpenes as vapor rather than smoke for a cleaner experience.
Temperature Guide for Vaporization
Temperature is the defining variable in vaporization. Different cannabinoids and terpenes have distinct boiling points, meaning you can dial in very specific effects by adjusting temperature. Low temperature (160-180C): Primarily activates lighter terpenes like limonene and pinene. Effects are clear-headed, energetic, and flavorful. Vapor is thin and light. Ideal for daytime use or creative activities. See our limonene terpene guide for details on these effects. Medium temperature (180-200C): The sweet spot for most users. THC vaporizes fully at 157C, CBD at 160-180C. Medium temperatures activate the majority of the cannabis plant's compounds for a balanced effect covering both euphoria and relaxation. High temperature (200-230C): Maximum cannabinoid extraction. Vapor is thicker, more sedating, and more likely to irritate the throat. CBN, which produces heavy, sleepy effects, becomes more active at these temperatures. Never exceed 230C — above this point combustion begins and you lose the benefits of vaporization.
Convection vs Conduction Heating
All vaporizers heat cannabis through one of two methods: conduction or convection. Understanding the difference helps you choose the right device. Conduction vaporizers heat cannabis through direct contact with a hot surface — like a hot plate. This method heats quickly and works well but can lead to uneven vaporization and occasional hot spots. Budget and mid-range devices typically use conduction. Examples include the Pax 3 and Arizer Solo 2. Convection vaporizers pass hot air through the cannabis without direct contact, similar to a convection oven. This produces the most even vapor and preserves terpenes most effectively, but devices typically cost more and take longer to heat. High-end desktop units like the Volcano Medic (reviewed in our desktop vaporizers guide) use convection. Hybrid vaporizers combine both methods for a balance of speed and quality.

Vaporizing vs Smoking: The Key Differences
The research on vaporization versus smoking shows clear advantages for vaporization in terms of respiratory health. Combustion produces carbon monoxide, benzene, and dozens of other harmful byproducts. Vaporization produces significantly fewer harmful compounds at properly controlled temperatures. Bioavailability is another major advantage. Smoking delivers roughly 15-25% of available cannabinoids due to combustion loss and incomplete absorption. Vaporization delivers 50-80% of available cannabinoids, meaning you achieve similar effects with significantly less cannabis. This directly translates to cost savings and reduced consumption. The experience itself differs too. Vapor has a more pronounced flavor profile because terpenes are preserved rather than burned. Many users describe vaporized cannabis as having a lighter, cleaner effect onset. The effect duration is similar to smoking. The main trade-off is cost: quality vaporizers represent an upfront investment, though long-term savings on cannabis offset this. For a detailed breakdown, see our vaping vs smoking comparison.
Caring for Your Vaporizer
A well-maintained vaporizer performs better and lasts longer. The most important maintenance step is regular cleaning of the herb chamber and vapor path. Resin buildup in the vapor path imparts harsh, burned flavors and can reduce airflow significantly. Clean the herb chamber after every 5-10 sessions with a small brush (most vaporizers include one). Remove loose debris and brush the heating element gently. For the vapor path (mouthpiece and screens), soak removable parts in isopropyl alcohol for 30 minutes, then rinse with warm water and dry completely before reassembly. Replace screens when they become visibly clogged — usually every 20-30 sessions for regular users. Keeping the charging port clean and storing the device at room temperature extends battery life in portable devices. Desktop units need less maintenance but benefit from occasional cleaning of the whip (tubing) with a pipe cleaner. Proper care keeps your device producing clean, flavorful vapor session after session.
Step-by-Step Guide
Grind to a fine-medium consistency for maximum surface area and efficient vapor production. Finer than for smoking, but not powder.
Turn on the device and allow it to reach your target temperature. Most vaporizers signal readiness with a light or vibration (30-120 seconds).
Pack the herb chamber loosely to 2/3 full. Overpacking restricts airflow; too little cannabis produces thin vapor.
Start at 170-180C for flavor-focused sessions. Increase to 200-210C for stronger effects. Never exceed 230C to avoid combustion.
Inhale slowly and steadily for 5-8 seconds. Vaporizer vapor is cooler and less visible than smoke — do not mistake thin vapor for ineffective vapor.
After 3-4 draws, open the chamber and stir the cannabis with a small tool to expose fresh material to the heating element.
Brown, spent cannabis from the vaporizer (called AVB or ABV) still contains cannabinoids. Save it for edibles or capsules.
