Participants in the mindfulness group will receive mindfulness based instructions.

Participants in the control group will receive instructions to cope with cravings how they normally would.

The mindfulness intervention includes strategies to cope with substance cravings based on previously published mindfulness techniques. Examples of strategies presented include paying close attention to sensations, acceptance of cravings, and self-kindness.

The participant's ratings of subjective likeability and helpfulness of the intervention. These ratings will be measured on a 5-point Likert Scale with higher scores representing more likeability and helpfulness. The 11-item questionnaire results in a score ranging from 11-55.

An online version of the TLFB (Sobbel & Sobbel, 1992) will be used to measure past-month cigarette and e-cigarette use. The measure will be administered pre-intervention and one-month following the intervention to show change over time.

Craving to smoke will be measured using the 10-item Brief Questionnaire of Smoking Urges (Cox, Tiffany, & Christen, 2001).While the QSU-brief can be scored by using all 10 items for one total craving score, maximum likelihood factor analysis of the QSU-brief revealed a two-factor model consisting of (1) a strong desire and intention to smoke with the perception of receiving positive rewards from smoking and (2) the expectation that smoking would relieve negative affect and the strong desire to smoke. The measure will be administered immediately preceding and following the intervention to show intervention influence on craving.

Positive and negative affect will be measured by the Positive and Negative Affect Schedule (Watson & Clark, 1999).

Number of times participants viewed intervention between intervention completion and one-month follow-up.
