This strain lives up to its perilous name, delivering wickedly potent THC levels that top 30% in some tests. That puts Black Widow on a very short list of the strongest marijuana strains of all time. With Sativa-dominant genes (Sativa/Indica ratio of at least 30:70), this strain provides an exceptional head high with remarkably intense euphoria, powerful happiness, deep relaxation, and a major cause of the munchies. Black Widow is only recommended for patients who have been toking for a while, as its intensity can overwhelm novice users and potentially trigger panic attacks. But for those who can tolerate the venom, this strain is good for depression, physical pain, muscle spasms, headaches, and everyday stress. It’s also perfect for inducing hunger in patients with wasting or eating disorders. Black Widow, surprisingly enough, isn’t a descendant of the more famous White Widow; rather, they’re siblings or cousins, descending from the same unknown Brazilian Sativa and an Indica from South India. Anticipate dry mouth and bloodshot eyes, while dizziness, headaches, and paranoia are less likely side effects. Black Widow sells well almost everywhere, but it’s most popular on the legal markets in California, Colorado, Oregon, Washington State, and Michigan.
