Accepts healthy volunteers: yes
Allocation: NA
Intervention model: SINGLE_GROUP
Intervention model description: Each subjects gets two procedure days with heating applied for one hour at hours 4 and hour 8 after the application of the Nicoderm CQ nicotine patch, then followed by two procedure days with heating applied for one hour at hours 4 and hour 8, after the application of the Aveva nicotine patch (total of four Procedure days)
Primary purpose: BASIC_SCIENCE

Brief summary: This is a single-dose, Open-label, Non-Randomized, 2-way Crossover Bioequivalence Study to compare nicotine release after heating of a brand name (Nicoderm CQ) and generic (Aveva skin patch) nicotine skin patches in adult smokers.

Detailed description: This research study is intended to determine the effect of heat on FDA-approved nicotine transdermal patches and whether the heat applied will result in more nicotine being absorbed through the skin than without applying heat. This is important given that little is known about how the release of nicotine is affected by heat, particularly for generic products that are also available over the counter. This study will use nicotine patches (brand name and generic patches) that have been approved by the Food and Drug Administration (FDA) and are already sold over the counter to customers in the United States, and will not include any placebos.

* 11. Have a diagnosis of schizophrenia or other major psychiatric diagnosis.
* 12. Received an experimental agent (vaccine, drug, biologic, device, blood product or medication) within 1 month before enrollment in this study or expects to receive an experimental agent during the study.

* 20. History of significant dermatologic cancers (e.g. melanoma, squamous cell carcinoma), except basal cell carcinomas that were superficial and did not involve the investigative site.
* 21. Within 10 hours prior to dosing, use of other nicotine products (e.g. nicotine gum or other nicotine-containing products) that would significantly influence or exaggerate responses to the nicotine patches used in this study.
