This gas-smelling strain gives off such an intense aroma that users may be forced to purchase one of its namesakes. This means that Gas Mask is best left to users and growers who are isolated or who don’t mind broadcasting their marijuana habits. An indica hybrid, this strain traces its genetics back to Cherry Pie and Alien Kush parent strains. Its effects are centered on feelings of blissful transcendence and full body relaxation properties, making it great for dealing with chronic pain. It will put users to sleep pretty handily, though, so make sure to use this one at night.
