This is the first human laboratory study of a loose-leaf tobacco vaporizer (LLTV). LLTV use significantly increased plasma nicotine concentration, but not CO. LLTV use reduced tobacco abstinence symptom severity, but less so than a cigarette. Both the LLTV and an ECIG were significantly less satisfying than cigarettes. Laboratory methods can be expanded to “heat-not-burn” products.
