Latest Reviews- Dry Herb Vaporizers

What are Dry Herb Vaporizers?

Dry herb vaporizers are (usually portable) devices used to vaporize dried plant material (typically Cannabis). Instead of burning the herbs, which produces smoke, these vaporizers heat the herbs to a temperature (350-400F ) that releases the active ingredients (Cannabinoids, Terpenes) in the form of vapor.

Using a dry herb vape has multiple benefits when compared to burning your flower, as it provides cleaner, more consistent, and predictable results.

Benefits of Using Dry Herb Vaporizers

Healthier Alternative to SmokingUnlike smoking, which involves combustion and releases harmful tar and carcinogens, vaporizers heat the herbs at a lower temperature. This process produces vapor, not smoke, which, according to research published by the National Library of Medicine, contains fewer toxins and is less harsh on the lungs. Users who switched to vaping (myself included) report that using a vaporizer is much easier on the lung.

Enhanced Flavor

Using dry herb vaporizers unlocks a whole new world of flavors and aromas. Smoking Cannabis means that you are burning the terpenes, which are the flavor molecules of the plant, plus the smoke overpowers any natural taste or aroma of the plant. Vaporization works at lower temps and preserves even the slightest notes of each specific strain.

More Potent

Controlled heating also ensures that the Cannabinoids and Terpenes are efficiently extracted, often resulting in a more potent effect than smoking (as per this research by PMC). As I mentioned, instead of burning away most of the active compounds, a vaporizer will preserve them and release them as potent vapor.

Discreet and Convenient

Most dry herb vaporizers are designed for discretion and convenience. Portable vaporizers are battery-operated and can be used at home or on the go. Using a vaporizer attracts a lot less attention, and most people won’t even have an idea what you’re doing. Additionally, while using vapes does smell, it is much less intense and dissipates more quickly than smoke, making it a subtler, more discreet option.

Cost-Effective in the Long Run

While the initial investment in a quality vaporizer might be significant, vaporizers are often more economical over time. They use herbs more efficiently, meaning you consume less material for the same effect. A typical vaporizer has a chamber size of 0.25gr, which is a quarter of the amount that is packed in an average preroll.

Controlled & Consistent Results

Vaporizers offer controlled temperatures, which not only maximize efficiency but also ensure a consistent flavor and potency in each session. This level of predictability is especially beneficial for medicinal users who rely on steady dosages and effects, as well as for recreational users who prefer a uniform experience each time.

Common Features

Temperature Control

One of the most significant features is temperature control. Entry-level vapes typically come with a few preset options, while more advanced vapes will allow a precise temp control of +/- 1°F. Temp control is crucial for optimal extraction and for customizing the vapor’s intensity and flavor.

Heating Methods

Vaporizers typically employ either conduction or convection heating methods. Conduction vaporizers heat the herb by direct contact with a heated surface, while convection vaporizers use hot air to heat the herb and extract the vapor. Some Hybrid vaporizers combine both methods for optimal efficiency.

Chamber Material

Common materials include ceramic, stainless steel, and glass, each offering different benefits in terms of heat distribution and flavor preservation. Ceramic is the most common, thanks to its heat-retaining properties and its natural non-stick surface.

Portability and Design

The size and design of vaporizers vary, with options ranging from discreet, pen-like devices to larger units that are designed for home use (aka Desktop Vaporizers). Keep in mind that the smaller a vape is, the shorter its battery life is. Plus, the heat has nowhere to dissipate, so expect the vape to get hot during use.

Concentrate compaibility

Some herb vaporizers also allow the use of concentrate, using a small pad or insert that is placed in the chamber. These vapes allow the use of concentrates as a secondary function, and it is not their main function. I recommend using your vaporizer exclusively with herbs and getting a wax pen or concentrate vaporizer for your extracts.

How to Use a Dry Herb Vaporizer

The usage process depends on the specific vape and the manufacturer’s instructions but typically involves the following:

1. Grind the Herbs: A consistent, fine grind increases the surface area, allowing for even heat distribution and efficient extraction.
2. Load the Chamber: Open the heating chamber and carefully fill it with the ground herbs. Conduction vapes should be packed tightly, while convection vapes should be packed loosely.
3. Set the Temperature: A good starting point is around 370°F (188°C). This temperature is ideal for enjoying the terpenes and subtle flavors of the herbs while still getting thick and satisfying vapor.
4. Inhalation: Once the vaporizer reaches the set temperature, inhale slowly and steadily through the mouthpiece. Begin with shorter draws to gauge the vapor’s potency and flavor.
5. Completing the Session: After use, empty the cashed herb, let the vape cool down a bit, and remove any leftovers.

Pro Tip:

In order to fully appreciate the flavors and effects of your herbs, start at a lower temperature to enjoy the delicate flavors and aromas. Gradually increase the temperature throughout your session to maximize extraction. This technique enhances the flavor and also ensures a complete extraction of cannabinoids.

How do dry herb vapes work?

Vaporization is a phase transition in which a substance changes from a solid or liquid state into a gas. In the context of dry herb vaporizers, this involves heating the herbs to a point where their active compounds turn into vapor without reaching the combustion temperature, therefore avoiding the production of smoke.

Vaporization usually happens between 356°F and 428°F (180°C – 220°C), which is below the combustion point. During vaporization, heat energy is absorbed by the herb, causing its molecules to vibrate more rapidly. This increased molecular activity releases volatile compounds (like THC, CBD, and terpenes) in the form of vapor. These compounds are bound within the plant fibers and require sufficient thermal energy to break free.

Cannabinoids and Terpenes

In dry herbs like Cannabis, cannabinoids (such as THC and CBD) and terpenes (responsible for flavor and aroma) exist in a crystalline form. The heat causes these crystals to transition from a solid to a gaseous state.

Cleaning and Maintenance

Residue from the herbs can build up over time, affecting the flavor and function, so regular cleaning is essential to get the most out of your vape.

1. Disassemble the Vaporizer: Carefully take apart any removable parts of the vaporizer, such as the mouthpiece, chamber, and any filters.
2. Clean the Chamber: Use a brush or a cotton swab dipped in isopropyl alcohol to clean the chamber gently. Avoid using water, as it can damage the heating elements.
3. Cleaning Other Components: Use alcohol wipes to clean the mouthpiece and any screens or filters. For tougher residues, soak these parts in isopropyl alcohol for a few minutes.

Legal Considerations

1. Follow Local Laws: Generally speaking, dry herb vaporizers are only hardware and, therefore, are legal to sell, ship, or carry around. Cannabis, on the other hand, is only legal in certain states/countries and may have restrictions on use/possession. It’s essential to be aware of and comply with local, state, and federal laws. Buy herb only from licensed dispensaries and use legally and responsibly.
2. Age Restrictions: There are typically age restrictions on the purchase and use of vaporizers. Most regions require individuals to be at least 18 or 21 years old to legally purchase and use these devices.
3. Public Usage: Even in areas where using a dry herb vaporizer is legal, there may be restrictions on public usage. Many places have laws against the public consumption of Cannabis, similar to public alcohol consumption laws.
4. Travel Considerations: Traveling with a dry herb vape is typically not a problem. Just follow the TSA guidelines for battery storage and transportation.

Safety Considerations

1. Quality of the Device: Invest in a high-quality vaporizer from a reputable manufacturer. Cheaper, lower-quality devices might not only perform poorly but could also pose safety risks, such as overheating or off-gassing.
2. Battery Safety: It’s important to handle and charge vaporizers properly to prevent issues like overheating or battery explosions. Use the charger that comes with the device and dispose of the batteries according to the EPA guidelines.
3. Regular Cleaning: Keep your vaporizer clean to prevent the build-up of residue, which can degrade performance and potentially release harmful substances when reheated.
4. Health Precautions: Individuals with respiratory issues or other health conditions should consult with a healthcare professional before using a dry herb vaporizer.
