Study Arms:
- vape NFEC containing 100% PG (Type: EXPERIMENTAL): Subjects will then be instructed how to use the NFEC (eGo-T® with light emitting diode (LED) display) for 1 week of regularly vaping NFEC containing 100% Propylene Glycol . Subjects will be given the eGo-T®, which contains a 1.2 ml refillable cartridge and a 1100 mAh battery with an LED display to record the number of puffs. Subjects will be asked to puff 100x per day (equivalent to \~10-11 cigarettes) for 7 days. We will accept a vaping range of 80-120 times a day.
- vape 100% vegetable glycerin -VG (Type: EXPERIMENTAL): Subjects will then be instructed how to use the NFEC (eGo-T® with LED display) for 1 week of regularly vaping NFEC containing 100% VG. Subjects will be given the eGo-T®, which contains a 1.2 ml refillable cartridge and a 1100 mAh battery with an LED display to record the number of puffs. Subjects will be asked to puff 100x per day (equivalent to \~10-11 cigarettes) for 7 days. We will accept a vaping range of 80-120 times a day.
- vape PG+VG (Type: EXPERIMENTAL): Subjects will then be instructed how to use the NFEC (eGo-T® with LED display) for 1 week of regularly vaping NFEC containing 50% PG and 50% VG. Subjects will be given the eGo-T®, which contains a 1.2 ml refillable cartridge and a 1100 milliamp hours (mAh) battery with an LED display to record the number of puffs. Subjects will be asked to puff 100x per day (equivalent to \~10-11 cigarettes) for 7 days. We will accept a vaping range of 80-120 times a day.
