THC: 29.44% Gas Face is a hybrid combining Face Mints with a Biscotti x Sherbet backcross. Despite the name, marijuana has a delightful butter and mint flavor, with hints of skunk and tropical fruits on the exhale. Despite its strong sedative effects, the Gas Face strain is best in the afternoon. It is due to Indica and Sativa balance, which boosts the brain when the body is calm.
