Low Nicotine Content Cigarettes in Vulnerable Populations: Affective Disorders

2019-09-20 03:46:45 | BioPortfolio


While the prevalence of smoking in the US general population has declined over the past 50 years, there has been little to no decline among people with mental health conditions. Affective Disorders (ADs) are the most common mental health conditions in the US, and over 40% of people with ADs are current smokers. A national policy of reducing the nicotine content of cigarettes has the potential to reduce tobacco use, dependence, and related adverse health outcomes. Controlled trials in psychiatrically-stable smokers have shown that reducing the nicotine content in cigarettes can reduce cigarettes per day (CPD), dependence and tobacco toxicant exposure, with few adverse consequences.

The goal of the proposed trial is to experimentally model whether increasing the availability and availability and appeal of an alternative, non-combusted source of nicotine (e-cigarettes) moderates the effect of altering the nicotine in cigarettes in smokers with ADs. Additionally, we will test whether allowing participants to personalize the flavor of the e-liquid alters any moderating effects their availability may have on tobacco cigarette smoking.

Daily smokers with current ADs will be recruited at Brown University and the University of Vermont.

We will study two research cigarettes referred to here as RC1 and RC2. One of these cigarettes will be a normal nicotine content cigarette and the other will be a reduced nicotine content cigarette. We will study two e-cigarette conditions referred to here as EC1 and EC2. Both e-cigarette conditions will involve the same commercially available devices and same nicotine-containing e-liquid, but in one condition that e-liquid will be available only in tobacco flavor while in the other condition that e-liquid will be available in multiple flavors from which participants can choose based on personal taste preference. Participants will be assigned to one of the following four study conditions: (1) RC1 only; (2) RC2 only; (3) RC2 + EC1; (4) RC2 + EC2.

Participants will be asked to use only their assigned study products for 16 weeks. Outcome measures include total CPD, cigarette demand assessed by behavioral economics-based purchase tasks, craving, withdrawal, psychiatric symptoms, breath carbon monoxide (CO), biomarkers of tobacco toxicant exposure, brain function and structure, and airway inflammation (fractional nitric oxide concentration in exhaled breath [FeNO]).

Medical and Biotech [MESH] Definitions

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.

The act of inhaling and exhaling vapors produced from ELECTRONIC CIGARETTES.


Tobacco used to the detriment of a person's health or social functioning. Tobacco dependence is included.
