Black Diamond, which is otherwise referred to as 'Black Diamond OG' and sometimes as 'Black Diamond OG Kush', is a Northern California strain of cannabis. This is an indica-dominant strain and is considered as a rare strain. The aroma of this particular strain is found to be earthy and musky and will be more or less like that of red wine. When the users sniff-up closer, this strain smells highly pungent. The taste would be similar to the smell and the taste of strong indica will be left in the user's throat for some time. This strain is recommended to be used as a nighttime smoke by insomnia patients as this highly sedative.
