Black Diamond, which is often referred to as ‘Black Diamond OG’ is the medical marijuana strain that is bred in the Northern California region as clone-only strain. A cross between Blackberry and Diamond OG, its flowers have a glittery trichome covering and purple coloring that make it beautiful to look at. This indica-dominant strain has high levels of THC which range between 18 and 24%. The strain’s aroma is musky and earthy, almost like a deep red wine and very pungent with a taste to match. This strain is recommended as a nighttime smoke by medical patients as it is highly sedative but can also be used for alleviating insomnia, pains, muscle spasms, nausea, anxiety and loss of appetite.
