Vaporizer Temperatures For Cannabis – The Ultimate Guide

One way to get to know your vaporizer well, is to just play around with the temperature settings – after all, it‘s pleasant research. But a slightly more scientific approach is to get to know the boiling points of the different cannabinoids and their properties.

Vaporizing cannabis can be a much better alternative to a joint. Vapor contains fewer harmful substances than smoke, and will provide you with a purer experience so you can enjoy more of the “good stuff” in cannabis. But the right temperature when vaporizing can make a big difference, not just for flavour, but also for your health.

Sure thing, smoking a good old joint is a timeless ritual—but vaporising has many benefits. For starters, vaporizing is healthier than smoking. Vaporizing doesn’t combust your herb, so you’re inhaling fewer of the harmful toxins present in smoke.

Vaping also makes for a purer cannabis experience. The smoke from your joint only contains around 10% of cannabinoids (the “good stuff”) in cannabis—the rest is a combination of unhealthy byproducts. Vapor clouds contain as much as 95% of the goodies from your weed. This makes them very pure and a lot more potent.

But know that when using a vaporizer, the right temperature setting can make all the difference!

One way to get to know your vaporizer well, is to just play around with the temperature settings – after all, it‘s pleasant research. But a slightly more scientific approach is to get to know the boiling points of the different cannabinoids and their properties. Now that‘s fun applied science!

The Importance Of The Right Vaping Temperature

Setting your vaporizer to the right temperature is important for several reasons. If you set the temperature too low, you will be missing out on flavour and potency. The crucial compounds found in cannabis and other herbs require a certain minimum temperature to “activate”. If your vaporizing temperature is set too low, you’re not getting the full potential out of your precious buds or concentrate.

On the other hand, if you set your vaporizing temperature too high (especially at temperatures higher than 230°C (446°F), this can degrade active substances in weed like terpenes and cannabinoids. Not only will the potency and flavour of your vape be adversely affected, but you may also inhale more toxic compounds detrimental to your health.

What’s The Perfect Temperature?

Before exploring the depths of cannabinoid boiling temperatures, here are the key findings: There‘s a temperature range in which different compounds of cannabis are released, each showing unique qualities in effect.

While only experimentation will show you the high that suits you best, an ideal temperature to extract a wide range of psychoactive compounds is 185 °C. The optimal temperature range for cannabis is between 180 – 210 °C. Temperatures below 190 °C. tend to produce a more cerebral high, temperature above that tend to induce a body high.

Cannabinoid Temperature Guide

The range of temperature in which all cannabinoids evaporate lies between 157 and 220 degrees Celsius. As all cannabinoids have different boiling points, vaporizing the same bowl of herb at different temperatures will generate different results. In general, there‘s two main effects which we will call the “buzz high” and the “body high”. As mentioned above, lower temperatures will have more of a heady effect, whilst higher temperatures will have a more body load effect.

Compound °C Information
THC 157°C THC is the most famous of all the cannabinoids. It has both euphoric and relaxing effects.
CBD 170°C Famous for its versatility and non-psychotropic nature, CBD is also thought to modulate the effects of THC.
Delta-8-THC 175°C This cannabinoid is very similar to THC, but it is more stable and less psychoactive.
CBN 185°C CBN results from THC’s degradation and has a soothing, non-intoxicating effect.
CBC 220°C Cannabichromene is one of the main cannabinoids found in cannabis, stemming from “mother cannabinoid” CBGA, just like CBD and THC.
THCV 220°C THCV has been shown to moderate the psychoactive effects of THC, but more research is required.

Flavonoid Temperature Guide

Along with terpenoids, flavonoids are little known compared to the famed cannabinoids. Flavonoids are a large class of plant pigments that are sometimes referred to as Vitamin P. Terpenoids and Flavonoids are partly responsible for the looks, taste and smell of a particular strain. They are the reason we open the zip lock before we buy, because their smell reveals a lot about the character of the plant.

The following outlines both the effects and the temperatures at which the flavonoids vaporize at.

Compound °C Information
Beta-sitosterol 134°C This flavonoid can be found in nuts and avocados, as well as cannabis.
Apigenin 178°C A flavonoid found in chamomile tea, apigenin exerts soothing and possible sleep-promoting properties.
Cannflavin A 182°C This flavonoid is a COX inhibitor.
Quercetin 250°C With its bitter taste, this flavonoid is continually being studied for its potential use as a natural care product.

Terpenoid Temperature Guide

Terpenoids are structurally related to terpenes and are naturally occurring in a wide range of plants. In part, they contribute to what what gives plants their unique aromatic quality. The scent of cinnamon, cloves and menthol are examples of well known terpenoids. In fact, the strongest known naturally occurring psychedelic compound – Salvinorin A – is a terpenoid.

The following descriptions outline both the effects and boiling points of terpenoids.

A naturally occurring oil found in plants such as cannabis, beta-myrcene is often used in fragrances.

What About Toxins When You Are Vaporizing?

Vaping is a lot cleaner than smoking, but this doesn’t mean it’s devoid of any potentially harmful substances. There is still the possibility of inhaling toxins, albeit in dramatically reduced concentrations. Moreover, unless you source your weed from a legal establishment—or grow it yourself—there could be small amounts of herbicides or pesticides still present in the plant material. After all, unless you are growing your own weed, how do you know what was used to grow it?

And then there is also the possibility that the material your vaporizer is made of may contain something that you don’t want in your body either.

What’s important to know is that setting your vaporizer to temperatures above 200°C (392°F) means you are approaching combustion temperatures. This is the point where the undesired substances in your plant material or vaporizer are released. Because of this, it is best to avoid high vaporizing temperatures unless necessary. In the table below, you can see which toxins are released at which temperatures.

What To Do If Your Cannabis Is Too Moist Or Too Dry?

Unlike when you use a bong or smoke a joint, bone dry cannabis can still be a delight in a vaporizer. However, because it is so dry, it will vaporize much faster – if it is too hot you run the risk of flash boiling the active ingredients, eliminating taste and flavour.

As it is largely going to depend on the situation and cannabis strain you are using, there is no definitive guide to how to properly vaporize particularly dry weed; but as a rule of thumb you will want to reduce the temperature from your norm, going lower the drier it is.

Conversely, if your bud is fresh, then it may be very high in moisture. As a result, it can sometimes be hard to get cannabinoids out. To deal with this, it is recommended to do what‘s called a flavonoid run. By putting the vaporizer at a lower temperature (around 138 – 148 °C.), it is possible to gain a bag of flavonoid vapour whilst slowly drying out your cannabis a bit. After this run, your cannabis should be dry enough to vaporize efficiently at THC and other cannabinoid temperatures.

Vaporizers work by heating up marijuana to the point were certain cannabinoids “boil” and literally evaporate, leaving behind just fibrous plant matter

Cannabis Chemistry: What To Know About Evaporation Post-Harvest

As margins shrink in a hyper-competitive industry, cultivators would be wise to ensure their flower stands out for the right reasons; and moisture retention is the biggest key. Paying attention to humidity control post-harvest makes a big difference, particularly with maintaining quality and value, which can help separate one cultivator from another.

While some may rush to harvest flower for processing, the ones who realize the importance of moisture retention will create a better overall product, and, thus, impact retailers, consumers and, ultimately, the cultivator’s bottom line.

How Insufficient Humidity Affects Cannabis Chemistry

More than 100 cannabinoids have been identified in the cannabis plant, and a growing body of scientific research is revealing how they interact with our bodies in profound ways, beyond just the well-known euphoric effects of THC.Meanwhile, terpenes, the organic compounds that create a plant’s distinctive aroma, are also receiving more scientific scrutiny, as they’re believed to play a significant role in the therapeutic effects of cannabis. The interaction of the various plant compounds is what researchers have dubbed the “entourage effect” — this complex interplay of cannabis components within the body’s endocannabinoid system.

When harvested cannabis dries too much, trichomes become brittle, fragile and can break off. Likewise, terpenes also evaporate when trichomes are exposed to conditions that allow oxidation to occur. Once lost, neither trichomes nor terpenes can be recovered, even if the flower is rehydrated. Any loss of particular compounds alters the chemical composition of cannabis flower and can harm its therapeutic value, which is a concern for many consumers. And with cannabis buyers far more sophisticated in their knowledge of cannabis strains and quality, this is an important factor cultivator’s must consider.

Moisture Loss Equals Money Lost

Dry cannabis flower undercuts profit margins for marijuana cultivators, that’s a fact. Flower that’s too moist is prone to hazardous mold and microbial growth, so many cultivators, processors and packagers finish their cure and then store, package and sell their cannabis in a state that’s unfavorably dry.

At Boveda, we’ve found this to be true as well. Through an analysis of 72 flower samples sold in five legal state markets, nearly 70 percent of the samples came out overly dry and below the optimal relative humidity (RH) range of 58-62 percent. According to Boveda research, a mere 5 percent dip below the optimal RH threshold eliminates six pounds per every 1,000 pounds of cannabis flower. At $5 per gram wholesale, that works out to upwards of $13,500 in lost revenue — and that’s just at a 5 percent humidity drop.

While wholesale prices vary, this example illustrates the broad impact on the bottom line. So unless a company wants profits to literally evaporate into thin air, establishing proper humidity control is an absolute must.

How Two-Way Humidity Control Works

Despite the previously mentioned concerns, excessive post-harvest evaporation is entirely preventable. Two-way humidity control solutions add or remove water vapor from a package or container to maintain a constant, predetermined RH level. This ensures a consistent level of moisture weight inside the cannabis flower.

By utilizing specialized humidity controls, producers can keep the cannabis flower in the “just right” Goldilocks zone, which helps preserve quality and weight, while limiting the risk of mold and microbial growth that comes with an overly humid environment.

The potential benefits are notable, too. According to a third-party lab study which analyzed flower cured with two-way humidity control solutions designed to maintain RH at 62 percent, the cannabis retained 18 percent more terpenoids, and 23 percent more cannabinoids compared with a control. That’s a significant difference in quality.

Post-harvest humidity control holds the key to preserving quality, profits and peace of mind. Amid volatile wholesale prices, cultivators must maintain production quality standards in order to retain customers and continue to grow as a business.

After growing and caring for cannabis during harvest, the last thing a producer wants to do is ruin the finished product.
