Understanding How Cigarette Direct Mail Marketing Influences Smoking Behaviors Among High and Low Socioeconomic Status Young Adult Smokers

* INCLUSION CRITERIA: * Age: 18 to 29 years, given our focus on young adults. * Smoking status: Current smokers who report smoking every day and who have smoked at least 100 cigarettes in their lifetime with a breath carbon monoxide level greater than 6ppm per device guidelines * SES: For the purpose of the study, we will use the empirical groups from our analysis of the Current Population Survey -Tobacco Use Supplement data. Two groups are chosen based on their social determinants and prevalence of smoking. 1. Low SES: Young adults who do not have a four-year college degree, are not currently enrolled in a four-year college, were born in the US, and have an annual income less than $50,000. This is the group that has been shown to have the highest prevalence of smoking. 2. High SES: Young adults who are currently enrolled in or graduated from a four year college. This is the group that has been shown to have the lowest prevalence of smoking. * English proficiency: since study materials are available only in English, only participants who are able to understand English and follow instructions in English are to be enrolled. * Cognitive ability: Able to understand and willing to sign a written informed consent document. * General health: Participants need to be generally healthy, as defined as someone with no known significant health problems. Participants can have chronic health conditions if the condition is well managed. EXCLUSION CRITERIA: * Inability, in the judgment of the investigator, to understand and follow the requirements of the protocol. * Currently enrolled in high school. * Participants with eye conditions that restrict their ability to track an object with their eyes. * Participants with myopia, hyperopia, and/or astigmatism who cannot pass a simple vision test even with corrective lenses. * Participants with medical condition(s) that may be triggered by infrared radiation (e.g., epilepsy). * Self-reported use of alcohol, recreational drugs or prescription medications used for recreational purposes (e.g., amphetamines, cannabis, cocaine, MDMA, ketamines, LSD, opiates and opioids, tranquilizers or opioid analgesics) that may influence their judgement at the time of study in the past 12 hours before the study visit. * Participants who cannot see an object located between 15 to 27 inches away from them (the required distance between the computer screen and the participants for accurate eye-tracking), even with corrective contact lenses.
