G-13 Strain Cannabinoids

THC 20 - 21.75% Tetrahydrocannabinol, or THC, is a major cannabis chemical compound. It is a psychoactive element that stimulates dopamine release and induces euphoria or happiness. THC-rich strains may be helpful with such conditions as lack of appetite, chronic pains , etc. It is considered to be the primary active marijuana component.
CBD 0.46 - 0.82% Cannabidiol, or CBD, is a major compound in cannabis, which is non-psychoactive. It is also proved to counteract the side effects of the second major component THC. CBD is widely used for medicinal purposes in rubs, oils and so on. It is helpful in muscle pain cases, may treat arthritis and migraines. Even Greeks used it against pain, while Queen Victoria applied it to get rid of menstrual cramps.
CBC 0.49 - 1.21% Cannabichromene, or CBC, is a minor cannabinoid, meaning that its quantity in cannabis is quite little. Though it has the same origin as CBD and THC, it is different in functions. Without any psychoactive effects, it is an efficient cannabis compound in combating acne and depression. CBC produces analgesic, antibacterial and anti-inflammatory effects.
CBG 0.29 - 2.19% Cannabigerol, or CBG, is one of the minor cannabis compounds in adult plants. On the other hand, young ones contain a lot of this antibacterial and anti-inflammatory component. During the growth, CBG is converted into different cannabinoids, mostly THC and CBD. The compound itself increases appetite and decreases eye pressure.
CBN 0.1 - 0.22% Cannabinol, or CBN, is a trace element in cannabis that is considered to be mildly psychoactive. It appears from oxidation THC, exposed to light and heat. CBN is mostly contained in old cannabis and in traditional hashish. It is effective against insomnia, bacterial infections and appetite loss.
THCV 0.23 - 1.06% Tetrahydrocannabivarin, or THC-V, is a compound contained in cannabis in trace amounts. Even though it is close to THC molecularly, it is different in effects. This compound may be psychoactive only in large amounts. THC-V reduces blood sugar, controls appetite, stimulates bone growth, etc. African Sativa strains are the richest in THC-V.

G-13 Terpene Profile

Carene 0.23% Carene (also known as Delta-3 carene) is a terpene found in rosemary, lemons, pines, and cedars, offering citrusy and cypress aroma. Studies on mice showed that carene provides anti-inflammatory effects, as well as promotes bone health and chronic pain relief.
Pinene 0.1% Pinene is one of the most widespread terpenes in nature, found in pine trees, basil, nutmeg, parsley, and rosemary. Cannabis containing terpene (alpha-pinene or α-pinene) boasts a strong pine scent. Pinene is responsible for anti-inflammatory, pain-relieving, and anti-anxiety effects.
Ocimene 0.26% Ocimene (derived from the Ancient Greek word Ocimum meaning basil) is a terpene with sweet and herbaceous flavors, also boasting citrusy and woody undertones. Naturally, ocimene occurs in mint, parsley, orchids, hops, kumquats, mangoes, basil, bergamot, lavender, and pepper. Offers antifungal, anti-inflammatory, and antiviral properties.
Humulene 0.26% Humulene (also known as α-humulene) is one of the major terpenes found in cannabis, contributing to woody, earthy, spicy, herbaceous, and, mainly, floral aromas of cannabis. Used in modern medicine, humulene offers anti-inflammatory, antibacterial, and appetite suppressant effects, which have been well-researched by pharmaceutical companies.
Phellandrene 0.16% Phellandrene (also known as alpha- and beta-phellandrene) is one of the rare terpenes found in cannabis with antihyperalgesic and antidepressive properties. Phellandrene contributes to a minty, woody, and mildly citrus aroma in cannabis. Previously confused with limonene and pinene, phellandrene was eventually distinguished as a separate terpene common for eucalyptus. Also, it could be found in mint, dill, black pepper, cinnamon, parsley, pine, and lavender.
Total terpenes content 1.01%

The original G13 strain comprises purely Indica. However, the later developed ones showed 70% of Indica and 30% Sativa. It is made up of 24% THC and 0.65% CBD.
Nothing is known of the exact lineage of the G13. It is believed to be a combination of crossbreeds of different Afghani weeds. Some sources say, that this strain was created by US Government in 60s-70s, but there is little accurate information.
