CBD-Rich Strain Review: Jamaican Lion

First Grown By: Jamaican Lion was originally bred by a grower named Shadrock in 2006, which he brought to California when he moved there in 2007. He views this strain as his intellectual property and he has never let seeds or cutting out to the public, even the bud itself is very rare to see in stores.


Genetics: Jamaican Lion is a sativa-dominant cross between a Mountain Lion mother and a sativa strain called Jamaican Yarder. Mountain Lion is a sativa-dominant cross between the indica-dominant, Rock Bud, and the sativa, Lionheart. Mountain Lion is not ideal for indoor growing which is the original reason why Shadrock crossed in the Jamaican Yarder; the high amount of CBD was just an unknown bonus. Without lab testing, Shadrock had no idea what he had bred. The CBD content tends to be highest in the 9th week of flowering, yet it is recommended to harvest it in week eight if you are looking for a 1:1 ratio and less of a CBD-dominant phenotype.

Cannabinoid/Terpene Profile: Jamaican Lion is known to have a 1:1 ratio of CBD to THC making it ideal for anyone suffering from pain. CBD and THC both work wonderfully for pain using different mechanisms of action and have a synergistic effect, making this balanced ratio the best for nearly all types of pain. This strain has also been shown to regularly have over 8% CBD, from the very first testing of it back in 2008, up until it won a High Times Cannabis Cup in 2011. Can be found very rarely at dispensaries in the San Francisco Bay Area, and has been seen with CBD percentages even higher than 8%, up into the low teens.



History and Background: Jamaican Lion was one of the first six CBD-rich strains identified by the partnership of Harborside Health Center, Steephill Labs, and Project CBD during their lab testing project in 2008. In their early testing, a strain was not viewed as being a CBD-rich strain unless it had over 4% CBD, by those standards Jamaican Lion could be considered very rich in CBD. Shadrock first bred the strain while living in Massachusetts, then when he moved to California he was only able to bring seeds with him; one of which ended up being a female Jamaican Lion, which became his mother in California. Shadock has always used his strain to treat his back pain and feels it has an energetic and enlightening, cerebral effect, which is common with sativas. Due to its powerful pain relieving effects, and very pleasant herbal aroma , Jamaican Lion was the 2nd place winner in the 2011 San Francisco High Times Cannabis Cup's CBD-rich category.
