When we talk about the “potency” of a cannabis strains we refer to the plant's concentration levels of Tetrahydrocannabinol (THC), one of many compounds unique to marijuana, and how “high” it can get a consumer. Some cannabis users prefer strains with lower potencies to avoid some of the cerebral effects THC can cause. If you're looking for a marijuana strain with a consistently low-testing THC potency, consider the varieties we examine here.

Many newly-created strains contain relatively equal amounts of CBD and THC, but hybrid cultivars with the lowest levels of THC are usually the least potent varieties. Sour Tsunami, ACDC, Permafrost, and Harle-Tsu are just a handful of the hybrid strains that have been bred to exhibit low levels of THC. Ringo's Gift, a CBD-dominant hybrid named after a medical marijuana activist, is a well-known hybrid that is not very potent.

You may have heard how Cannabis sativa strains have a reputation for exhibiting naturally low levels of THC and higher levels of cannabidiol (CBD), which is another compound found in marijuana that behaves differently than THC and is non-psychoactive. Charlotte's Web is a famous sativa variety that contains only traces of THC and was bred to be used to treat epileptic seizures. Jack Herrer, Harlequin, and Maui Waui are more examples of the least potent sativa strains. 

Tora Bora, Pennywise, Sweet and Sour Widow, and Plushberry are a few of the least potent strains of Cannabis indica known to date. Where sativa varieties typically exhibit low THC levels, the opposite is true for indica varieties, so they may not be the best choice id you seek less potent strains.

Whether you are new to using cannabis or you just know you're a light weight customer, using one of the least potent strains of cannabis currently on the market is your best bet to avoid any unwanted side effects of THC. Gauging the potency of a cannabis strain for a specific user remains an imperfect science as each marijuana variety (thousands currently exist) will affect each consumer differently. Also, factors such as growing techniques, environmental conditions, and your method of consumption can cause variations in the potency of your latest bag of weed.
