Title: Acceptability, Patterns of Use and Safety of Electronic Cigarette in People With Mental Illness: a Pilot Study
Brief Summary: People with mental illness are more likely to smoke and are more severely addicted to nicotine than the general population. As a result, the number of deaths related to tobacco is higher.

Smoking is highly addictive because it delivers nicotine very quickly. Research studies show that people who use nicotine replacement therapies (such us patches, gums, etc) are more likely to quit smoking than those who try to quit without using these nicotine products. Recently a new electronic nicotine delivery system (ENDS), also known as electronic cigarette (e-cigarette) is rapidly gaining popularity. Electronic cigarettes are devices that mimic traditional cigarettes and deliver nicotine but do not carry the dangerous chemicals contained in tobacco cigarettes.

Given the increasing popularity of e-cigs, there is an urgent need to improve our understanding of both the potential benefits and risks of e-cigs use in people with serious mental illness. In this pilot we propose inviting 50 people with schizophrenia (or schizophrenia-related disorder) who are not intending to quit smoking in the near future to take part in a study in which we will provide 6-weeks of free e-cigs, followed by a 4-week period in which they will not receive free e-cigs and we monitor which products participants choose, and a final 24-week follow-up visit. During the 24-week study period we will assess the use of e-cigs and tobacco cigarettes, the exposure to nicotine and tobacco toxicants, nicotine withdrawal symptoms, the changes in respiratory symptoms and psychiatric symptoms as well as the e-cigs perceived benefits and risks.


Options:
A: reducers (week-24 from baseline)
B: Electronic cigarette use (weekly measurements from baseline to 10 weeks and a final assessment at 24 weeks); electronic cigarette acceptability (Baseline, week 2, week6, week 10 and week 24); Respiratory symptoms (weekly measures from baseline to 10 weeks and at 24 weeks); Cotinine (Baseline, week 2, 6, 10 and 24); Nitrosamines (Baseline and at 6 week); Side effects of antipsychotics (weekly the first 10 weeks and at 24 weeks); Withdrawal symptoms (weekly the first 10 weeks and at 24 weeks); Respiratory symptoms (weekly the first 10 weeks and at 24 weeks)
C: Rate of Smoking Abstinence (18 months & 24 months post study enrollment)
D: Determine Levels of nicotine effectively delivered by various types and brands of ENDS to the bloodstream and compare them to levels delivered from conventional cigarettes (Up to 1 year); Levels of nicotine effectively delivered by various types and brands of ENDS to the bloodstream and compare them to levels delivered from conventional cigarettes (Up to 1 year); Levels of nicotine effectively delivered by various types and brands of ENDS to the bloodstream and compare them to levels delivered from conventional cigarettes (up to 1 year); Changes in withdrawal symptoms (up to 1 year); Subjective nicotine effect will be analyzed (up to 1 year); Changes in feelings and emotions (up to 1 year)

Answer: B
