How many terpenes are in cannabis?

There are currently over 200 terpenes in the cannabis plant, although there are only a handful of terpenes that make up a majority of the cannabis products currently on the market. These include Myrcene, Pinene, Limonene, Caryophyllene, Linalool, Humulene to name a few.

What are the most common terpenes in cannabis?

Limonene is most common in lemons, oranges and limes, as well as in cannabis resin. This terpene explodes in the air when a fruit is peeled or buds are grinded. Plants use limonene to repulse predators. Limonene is the most abundant terpene in cannabis strains, and it’s a precursor for the synthesis of other cannabinoids. Limonene is easily absorbed by inhalation and quickly appears in the bloodstream. Since it’s known to affect the permeability of cell membranes, it allows more THC to reach the brain and increases the absorption of other terps.

Pinene causes the familiar aroma associated with pine trees and their resins, as well as many other conifers and a few non-coniferous plants such as big sagebrush. Pinene is also found in many essential oils produced by plants, including rosemary, sage and eucalyptus. It constitutes the major component of turpentine, contributing to its odor and properties as a solvent. Pinene easily crosses the blood-brain barrier and promotes alertness and memory retention, among other effects. It is also a bronchodilator, allowing the deeper inhalation of smoke or vapor and the greater absorption of cannabinoids and terpenoids.

Myrcene is one of the most prevalent terps in cannabis. It not only provides hints of flavor and aroma, but is a big contributor to the effects that a strain produces. Myrcene forms an important component of the essential oils of several plants besides cannabis, including lemongrass, bay, wild thyme, parsley, mango and hops. It has an aroma that has been variously described as hoppy, clove-like and earthy, with tropical, mango and minty nuances.

Linalool has a floral scent reminiscent of spring flowers such as lily, but with spicy overtones. It is prominent in lavender plants. Humans can detect its aroma at rates as low as one part per million in the air. In cannabis, trace amounts of linalool go a long way. When combined with trace amounts of terpinolene and limonene, its effects become amplified and sweeter, much like candy.

Terpinolene has a medium-strength, herbal aroma that’s been described by judges as fresh, woody and piney, with a hint of citrus. Terpinolene’s flavor is sweet and lemon-lime-like, with a slight floral nuance. It is used as a flavor and fragrance agent, as well as in soaps, detergents, creams, lotions and perfumes.

At what temperature to terpenes vaporize?

Many terpenes vaporize near the same temperature as THC (which boils at about 157°C), although some terpenes are more volatile than others and begin to vaporizer at lower temperatures.

What are the synergistic effects of terpenes?

The synergistic effects that terpenes have in conjunction with cannabinoids assist in creating what’s commonly referred to as the “entourage effect.” This interaction of elements can offer a result that is greater than the sum of the individual cannabinoids. According to studies the cannabinoid plant components such as terpenes increases the potential of cannabis-based medicinal extracts to treat pain, inflammation, fungal and bacterial infections, depression, anxiety, addiction, epilepsy and even cancer.

What is CBD and how does it work?

CBD is an abbreviation for cannabidiol, the most prominent naturally occurring cannabinoid component found in hemp, and comprises up to 40% of the hemp plant. According to the US Government, cannabidiol is “…devoid of psychoactive effect.” After THC (9-tetrahydrocannabinol), CBD is by far the most studied natural cannabinoid. Additionally, CBD is increasingly the subject of advanced medical research and may be the single most important cannabinoid ever discovered.

Are CBD and THC the same thing?

No, they are different compounds. CBD and THC are both cannabinoids, but THC produces psychoactive effects causing a drugged symptom commonly known as a “high”. Although all CBD extractions will contain some THC, our CBD hemp plants are selected, cultivated, and processed to eliminate all THC content and are therefore devoid of any psychoactive effects.

Is this medical cannabis and do I need a doctor’s recommendation? 

Because CBD is not psychoactive, a doctor’s recommendation is not necessary, however, we do advise you to consult your physician to be sure CBD is appropriate for you.

How much CBD should I use per day?

Sensitivities vary from person to person. Discretion is advised by and for each individual, based on experiential preference. However, as a loose guideline, 25 – 50 mg per dose and anywhere from 25 – 300 mg per day is our recommendation.

How is hemp different from marijuana? Why grow hemp and not marijuana for CBD?

Both hemp and marijuana are Cannabis sativa plants, however, the level of THC and other compounds differ. Marijuana has been bred to achieve high levels of THC for its psychoactive effects. Hemp grown for medical use is cultivated and processed to extract CBD and other cannabinoid oils with the lowest possible levels of THC, so there are no psychoactive effects from the use of the plant. We take it one step further and process the hemp oil to remove all traces of THC and isolate the CBD.

Are CBD Hemp products legal in the USA?

CBD, when extracted from hemp and not marijuana, IS legal in all 50 states. We do advise to be extra diligent and double check with local legislation in your area.

What is your refund policy?

Unfortunately, we cannot offer refunds for any opened items due to our own strict sanitation standards. However, if you’re experiencing technical issues with the cartridges or have any specific issues with a product, please email us at info@clearnation.com We usually do a good job of replying back within a day or two.

How long does shipping usually take?

Depending on your shipping location, domestic Priority shipping is typically 1-3 days. International times vary.

Why isn’t tracking on my international order working after customs?

If your tracking is not working after clearing customs  it should still be en route. Unfortunately USPS does not update tracking information outside of the USA, so after it hits customs you are sort of left in the dark until it arrives. In most cases however, packages are delivered within a week of going through customs. 

Why isn’t my tracking number working? 

If an order is placed after 5pm on friday, it unfortunately will not get processed until monday morning as our offices are closed on weekends.

If your tracking number is not working, we advise waiting a couple hours and trying again. Shipping confirmation emails are sent when we print the labels, but they don’t actually get put into the system until they are picked up and scanned by the post office, which for us typically happens around 5pm PST. 

How do I use the Perfectly Pure CBD Crystalline?

Can I add the isolate to an e-liquid?

Some customers like to add our crystalline to their favorite e-juices or vaping liquids, however this is sort of a tricky thing to master. Mixing our isolate with e-liquid is okay, but we recommend first dissolving your crystals in a carrier oil before introducing the isolate to a high VG blend. The crystalline is not water-soluble and therefore does not dissolve into VG, and the introduction of VG to the CBD solution can promote re-crystallization, which can easily clog up tanks. The general rule of thumb is the more CBD you use the greater the chance this type of re-crystallization will occur. If you are mixing your CBD with an e-liquid, we recommend using an RDA (rebuildable drip atomizer) so you can drip it directly onto coils to avoid clogging and potentially ruining your tank or RTA. Just remember, if this is something you want to try, proceed with caution!

Health Benefits & Risks of CBD

Any substance applied externally or ingested into the human body may affect individuals in different ways. CBD and other phytochemical constituents of hemp are considered to be generally safe and we are not aware of any reports of adverse effects. However, as with any therapeutic, cosmetic, or food product, at the first sign of a reaction or discomfort, use should be discontinued until consultation with your doctor.

 With respect to the beneficial properties of CBD, there have been numerous claims made about its positive effects for epilepsy, cancer, dementia, and multiple sclerosis.
