Chem D x SFV OG The Motorbreath high is just as potent as the flavor, with calming effects that are best suited for late nights when sleep just won't come. The high starts with a lifted relaxation that fills your mind with warm tingly euphoria and a sense of ease. A numbing body high comes next, lulling you into a slightly couch-locked and sedative state that can quickly leave you dozing off and on as the high continues.
