G13 Strain Overview

G13 may deliver mind-altering states of awareness and physical relaxation in small doses. Drizzled in trichomes and oozing with THC, G-13 earns its name from its unique origins. Although the specifics of its heritage remain top secret, various accounts claim that government agencies like the CIA and FBI initially bred G13. In the 1970s, an anonymous employee took a single plant out of the 23 Afghani cultivars, each designated a number (G1-G23), and gave it to breeder Nevil Schoenmakers.

G13 Strain Effects & Common Usage

Blending the psychotropic effects of THC with the anti-anxiety potential of CBG, G13 is a prime choice for patients seeking mental and physical relaxation.

Euphoria. THC is a mood-enhancing cannabinoid that promotes dopamine release.

Pain. Along with the pain-relieving potential of THC, the terpenes limonene, pinene, and myrcene have demonstrated anti-inflammatory properties and may help with pain relief.

Sleepiness. Myrcene, pinene, and THC may be fairly sedating in certain doses.

Anxiety. Limonene may exert anti-anxiety effects via DAergic and GABAergic neurotransmission.

Stress. Some studies demonstrate that caryophyllene has mood-enhancing and stress-relieving properties. CBG may also be suitable for subtle relaxation since it inhibits the uptake of GABA inside the brain.

Appetite loss. THC increases the production of ghrelin – the hunger hormone.

G13 Strain Dosage Recommendations

On average, G13 contains between 20% and 24% THC, which is on the high end of the spectrum, so start with small puffs and increase as needed. New consumers may want to start with a single puff or avoid this strain altogether.

The right dosage can vary greatly from one user to the next. If you have questions about finding the right dosage or product type for your needs, consider consulting with a medical cannabis doctor, or you can request a consultation with NuggMD’s Cannabis Concierge.
