So named for its funky, almost noxious odor, Gas Mask is a pungent indica-dominant hybrid. Created by Washington State-based growers Pacific NW Roots, Gas Mask is a cross between Cherry Pie and a specific phenotype of Alien Kush. What results is a seriously dank strain with an exceptionally long-lasting high. Sure to impress both cannabis newbies and veterans, Gas Mask’s THC content has been measured at between 20% and 27%.
