Scientists track every puff: heated tobacco study reveals Real-World smoking habits

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Post-menopausal who are not on hormone replacement therapy. * Males who self-report they are not willing to use a barrier method of contraception (e.g., a condom with spermicide) or to refrain from donating sperm from the time of signing the informed consent until the EOS, unless they have undergone a vasectomy or were abstinent from heterosexual intercourse, or their female partner was not able to bear children. * Individuals who self-report having pacemakers or other embedded electronic medical devices. * Individuals who self-report having an unstable heart condition, severe hypertension or diabetes. * Individuals who self-report they are sensitive to nicotine. * Individuals who respond with 'Poor' or 'Don't know' to general physical or mental health. * Individuals who have used a nicotine replacement therapy (NRT) product or a prescription drug to help stop smoking (e.g., varenicline, bupropion) in the past 30 days. * Individuals who are employed by a company that manufactures tobacco, HTPs, marketing or in ongoing litigation with a tobacco company. * Individuals who self-report that they are planning to quit all nicotine products in the next three months. * Individuals who are personally, have household members, or have close family or friends in ongoing or past litigation with a company that manufactures tobacco or HTPs. * People who have taken part in a tobacco/nicotine research study in the past 30 days.
