The Lowdown on Vaping Terpenes
Vaping has established itself as a popular alternative to smoking, and not just for tobacco. Many cannabis users also vape extracts rather than smoking cannabis flower.
If you’re vaping a cannabis product, there is a good chance that you’re also vaping terpenes, even if you do not know it. Terpenes help shape the product’s aroma and flavor, but questions remain about what happens when they are heated and inhaled.
So, what do terpenes contribute to a vape? Do they get you high, and is vaping them safe? Even if you have already bought and used terpenes from True Blue, you may still have questions.
The main takeaway is simple: terpenes do not produce the characteristic high associated with THC. They mainly contribute aroma and flavor. Vaping also avoids combustion, but that does not make terpene-containing aerosols harmless. Safety can depend on the formulation, concentration, device, temperature, and how the product is used.
What are terpenes?
If you’re reading the True Blue blog, you may already know what terpenes are. If you do not need a refresher, move along to the next section.
Terpenes are aromatic organic compounds that appear throughout nature. They lend flowers, herbs, and fruit much of their distinctive scent. Cannabis is one prominent example. Others include lavender, pine, eucalyptus, and lemon, each of which contains its own combination of terpenes.
In cannabis products, terpenes are best known for shaping aroma and flavor. Researchers are also studying whether certain terpenes have biological effects, but much of that research is based on laboratory or animal studies. It does not establish that vaping terpenes can treat pain, anxiety, inflammation, sleep problems, or other health conditions.
Terpenes may interact with cannabinoids and other compounds in cannabis, but their clinical importance is still uncertain. You can learn more about what terpenes are in our introductory guide.
Is vaping terpenes safe?
Vaping does not involve combustion, so it avoids the smoke and tar created when plant material is burned. However, that does not mean vaping is risk-free. A heated aerosol can still contain irritating or potentially harmful compounds, and the risks associated with nicotine vaping cannot automatically be applied to cannabis or terpene products.
Laboratory research has found that heating terpene-containing formulations can produce compounds such as benzene, methacrolein, and other volatile chemicals under some conditions. The amount and type of emissions can vary with temperature, terpene concentration, carrier ingredients, device design, coil condition, and puffing behavior.
Terpenes may already be present in a cannabis extract, or a manufacturer may add them to create a particular aroma and flavor profile. They are not required in every vape product, and they should not be treated as harmless simply because they occur naturally.
Consumers should use only products that are expressly formulated for inhalation and should follow the manufacturer’s instructions. Avoid modifying finished cartridges, using informal or unverified products, or vaping concentrated terpenes directly.
The 2019 outbreak of vaping-related lung injury was strongly associated with vitamin E acetate in many THC vaping products from informal sources. That finding does not mean that all other vape ingredients are safe. It highlights the importance of ingredient disclosure, reliable manufacturing, and avoiding unregulated products. See the CDC information on vaping-related lung injury for more context.
Stop using a vape product and seek medical attention if you experience chest pain, shortness of breath, persistent coughing, or other serious respiratory symptoms after vaping.
Do terpenes get you high?
The short answer is no. THC is the primary intoxicating compound in cannabis and is responsible for the characteristic cannabis high. Different strains and products can contain different amounts of THC, which can affect their potency.
CBD does not produce the same intoxicating effect as THC.
Terpenes do not produce a THC-like high either. Their aromas and flavors may influence how a person perceives a product, but that is different from intoxication.
You may also hear about the “entourage effect hypothesis.” This is the idea that cannabinoids, terpenes, and other cannabis compounds may work together in ways that affect the overall experience.
Some studies have compared isolated cannabinoids with broader plant extracts, but these comparisons do not prove that terpenes caused any difference in results. Extracts can contain many compounds, and current human evidence does not consistently show that terpenes enhance THC or CBD effects.
What do terpenes add to a vape?
Terpenes mainly add aroma, flavor, and character to a vape product. They can help reproduce the profile of a particular cannabis strain or create a fruit, herb, citrus, mint, or dessert-inspired flavor.
There are many different terpenes in cannabis, and the exact profile can vary by cultivar, growing conditions, storage, extraction, and processing.
Some of the most familiar cannabis terpenes include myrcene, limonene, and beta-caryophyllene.
Myrcene is common in many cannabis cultivars, although its concentration varies considerably. It has an earthy, musky aroma and is also found in hops, lemongrass, and mangoes. Myrcene has been studied for possible biological effects, but much of the evidence is preclinical and does not establish benefits from vaping it.
Limonene is abundant in the rinds of citrus fruits and has a bright citrus aroma. Due to its fragrance, it is commonly used in foods, perfumes, and flavor products. Claims that inhaled limonene can treat anxiety, depression, or inflammation are not supported by strong clinical evidence.
Beta-caryophyllene is known for a spicy, peppery aroma and is also found in black pepper, oregano, basil, and rosemary. Laboratory and animal studies have examined its interaction with cannabinoid receptors and other biological pathways, but those findings should not be interpreted as proof that vaping beta-caryophyllene treats pain, inflammation, or alcohol-related conditions in humans.
When comparing terpene products, look beyond whether the ingredients are described as “natural” or “synthetic.” Source alone does not determine inhalation safety. More useful checks include the product’s intended application, ingredient disclosure, batch documentation, testing information, and clear manufacturer instructions.

Can you add terpenes to a vape yourself?
Some people take a DIY approach by adding terpenes to an existing liquid or cartridge. However, creating or modifying an inhaled formulation is more complicated than adding flavor to a finished product.
Terpenes are highly concentrated. Using too much can make a product harsh or irritating, and not every terpene blend is compatible with every extract, carrier, cartridge, coil, or device. A generic mixing percentage cannot guarantee a safe or stable formulation.
Do not vape undiluted terpenes or add them to a finished cartridge unless the product is specifically intended for that use and the manufacturer provides clear, product-specific instructions. Avoid creating a vape liquid from propylene glycol, vegetable glycerin, cannabinoid oils, and terpene concentrates without appropriate formulation expertise and testing.
