The Chem 91 is thought to be an offshoot of the original Chemdawg strain. The numerical addition of “91” is believed to reference the year the strain first came into existence. This potent lady has a very strong diesel smell with a piney-lemon aftertaste. Our version of the Chem 91 tends to lean more on the Sativa side, however some users get more of a relaxed Indica high. Consumers should expect a cerebral buzz that is very euphoric and lasts for several hours.
