Black Mamba is thought to be a hybrid cross between Black Domina and Granddaddy Purple, two celebrated strains for their relaxing effects. Black Mamba is just the right marijuana strain for insomnia. The strain produces deeply sedating effects that relax the whole body and mind, fading away anxiety and depression in the process and allowing you to enjoy a deep uninterrupted sleep. Cancer patients can use Black Mamba to ease the agonizing side effects of chemotherapy. Available in prepackaged individual grams of shatter or bulk.
