Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.
An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.
The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Measure: Nicotine Content   #730300

Definition: This measures the amount of nicotine in tobacco products including smokeless tobacco, tobacco filler, and electronic cigarette liquid contents or refill solutions (e-liquids).

Purpose: The purpose of this measure is to analyze the pH and the amount of nicotine in smokeless tobacco, tobacco filler, and electronic cigarette liquid contents or refill solutions (e-liquids). Nicotine in tobacco exists predominantly in two pH-dependent forms. Protonated nicotine is the predominant form in tobacco, but additives of tobacco can increase pH and convert a fraction of the nicotine into the non-protonated free-base form that is more bio-available and readily absorbed, contributing to higher addictiveness.
