This study aims to determine the health effects of very low nicotine content in cigarettes, in conjunction with the availability of nicotine-containing electronic cigarettes (e-cigs) among smokers with mental health conditions (SMHC).
The specific objective of this study is to recruit a cohort of 240 current exclusive daily SMHC (diagnosed using the MINI International Neuropsychiatric Interview) and to measure a comprehensive battery of behavioral and health indicators at 4, 8, 12 and 16 weeks after being randomized to use either normal nicotine content (NNC) Spectrum cigarettes (11.6 mg nicotine/cigarette) or very low nicotine content (VLNC) Spectrum cigarettes (0.2 mg nicotine/cigarette) while also having access to an electronic cigarette (containing either 0 nicotine or high nicotine e-liquid) in a randomized double-blind, placebo-controlled, 2 by 2 design. All participants will be followed up with a study visit 4 weeks after the final randomized visit to identify whether they have continued to use e-cigs/cigarettes and to assess their motivation in smoking abstinence.
Our central hypothesis is that key markers of harms to health (e.g. urinary NNAL, exhaled CO, measures of addiction, and mental distress) will be significantly improved among SMHC who are provided VLNC cigarettes and high nicotine e-cigs.

Electronic devices that are designed to provide NICOTINE in the form of an inhaled aerosol. They typically are made in the shape of CIGARETTES in order to simulate the experience of CIGARETTE SMOKING.
Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.
