Brief Summary:
Electronic cigarettes have shown promise but have yet to proven effective for smoking cessation. This trial will evaluate the effectiveness of electronic cigarettes in smokers who are trying to quit smoking compared with a standard therapy, the nicotine inhaler. The investigators hypothesize that electronic cigarettes will be comparable to the nicotine inhaler in terms of smoking cessation.

Condition or disease Intervention/treatment Phase
Tobacco Use Disorder Other: electronic cigarette Drug: nicotine inhaler Not Applicable

Detailed Description:

Cigarette smoking remains the leading cause of preventable death and disease worldwide.

The purpose of this trial is to evaluate the effectiveness of electronic cigarettes for smoking cessation compared to a similar nicotine replacement therapy, the nicotine inhaler.

Arm Intervention/treatment
Experimental: electronic cigarette
electronic cigarette 24mg cartridges; 1-2 cartridges daily
Other: electronic cigarette
V2 Cigs with 24 mg nicotine cartridges

Active Comparator: nicotine inhaler
nicotine inhaler 10mg cartridge; max 16 cartridges daily

Primary Outcome Measures :
  1. Cigarettes smoked over 24 hours [ Time Frame: 4 weeks ]

Secondary Outcome Measures :
  1. Symptoms of nicotine withdrawal [ Time Frame: 4 weeks ]
    We will measure the incidence and severity of nicotine withdrawal symptoms, including irritability, anxiety, depressed mood and increased appetite.

  2. Benefits from smoking cessation [ Time Frame: 4 weeks ]
    we will measure perceived benefits from smoking cessation including improved breathing, improved sense of taste and smell, and improved physical fitness.

  3. Adverse reaction to nicotine inhaler or electronic cigarette [ Time Frame: 4 weeks ]
    we will assess for any possible side effect from the electronic cigarette or the nicotine inhaler, including irritation of the mouth and throat and cough.

Other Outcome Measures:
  1. Body mass index [ Time Frame: 4 weeks ]
    We will measure if body mass increases as a consequence of smoking cessation.
