G13
About G13
G13 is an indica-leaning strain. You may also see it sold as G-13, G Thirteen. People who try it most often describe feeling sleepy, euphoric and hungry.
THC and potency
Public lab results give a good picture of its strength: 25 flower samples tested between 2022 and 2024 came in at a median of 16% total THC (the middle half ranged from 14.5% to 17.6%). That is in line with most flower on Canadian shelves. Potency varies by grower and batch, so always check the label.
Aroma, flavour and terpenes
Its reported terpene profile is led by myrcene, with limonene and caryophyllene. Myrcene is known for earthy, musky notes with a ripe-fruit edge, while limonene adds bright citrus-peel freshness. Consumers most often describe the flavour as pine, earthy and woody.
Reported effects
Beyond feeling sleepy, reviewers also mention feeling happy and tingly. Some consumers say they reach for it when dealing with stress, pain and anxiety. The side effects mentioned most are dry mouth, dry eyes and dizziness. These are personal reports, not medical advice.
