Experimental: cigarette substitute
The QuitSmart cigarette substitute is a plastic tube that looks like a real cigarette and is designed to provide the same draw resistance as a smoker's usual cigarette.
There is no drug delivery with this product.
Two cigarette substitutes and a product manual are provided to participants following randomization and replacement products are provided throughout the intervention period (24 weeks).

|
|
Experimental: e-cigarette (with 0 mg/ml nicotine)
The e-cigarette used will be the EGO e-cigarette (marketed by www.liquidexpress.com).
Each participant randomized to an ECIG condition will receive 2 e-cigarette batteries, 1 wall adapter, 1 USB charger, and a user manual.
Cartomizers containing 0 mg/ml nicotine will be provided throughout the intervention period (24 weeks).
|
|
|
Experimental: e-cigarette (with 8 mg/ml nicotine)
The e-cigarette used will be the EGO e-cigarette (marketed by www.liquidexpress.com).
Each participant randomized to an ECIG condition will receive 2 e-cigarette batteries, 1 wall adapter, 1 USB charger, and a user manual.
Cartomizers containing 8 mg/ml nicotine will be provided throughout the intervention period (24 weeks).

|
Experimental: e-cigarette (with 36 mg/ml nicotine)
The e-cigarette used will be the EGO e-cigarette (marketed by www.liquidexpress.com).
Each participant randomized to an ECIG condition will receive 2 e-cigarette batteries, 1 wall adapter, 1 USB charger, and a user manual.
Cartomizers containing 36 mg/ml nicotine will be provided throughout the intervention period (24 weeks).
