IQOS for Smoking

This trial examines how cigarette smokers experience using IQOS heated tobacco products. The goal is to understand how these products might affect smoking habits and sensory experiences. Participants will try IQOS HeatSticks and their usual brand of cigarettes during separate lab visits. Those who smoke regularly, at least five days a week for the past three months, might be a good fit. Participants should be willing to refrain from using nicotine products for 12 hours before each visit. As an unphased trial, this study offers a unique opportunity to contribute to research that could shape future smoking alternatives.

The trial information does not specify if you need to stop taking your current medications. However, you must abstain from using nicotine products 12 hours before each visit.

Research shows that IQOS heated tobacco products (HTPs) are generally safer than regular cigarettes. Studies have found that IQOS users encounter much lower levels of harmful chemicals compared to those in cigarette smoke.

However, using IQOS still poses health risks, though likely less than smoking regular cigarettes. The FDA has acknowledged this reduced harm, but evidence on IQOS's effectiveness in helping people quit smoking remains limited. Additionally, some individuals might use both IQOS and regular cigarettes, potentially reducing the health benefits.

Researchers are excited about IQOS Heated Tobacco Products because they offer a novel way to reduce harm from smoking by heating tobacco instead of burning it. Unlike traditional cigarettes, which combust tobacco and produce harmful smoke, IQOS uses a unique heating mechanism that significantly reduces the release of toxic chemicals. This alternative delivery method aims to satisfy nicotine cravings while potentially minimizing the health risks associated with smoking conventional cigarettes.

This trial will compare IQOS Heated Tobacco Products with usual brand cigarettes. Studies have shown that IQOS can significantly reduce exposure to harmful chemicals, with reductions ranging from 20% to 99.9% compared to regular cigarettes. Research indicates that using IQOS can lower levels of harmful substances in urine and blood. However, evidence remains limited regarding IQOS's effectiveness for quitting smoking. Some users have smoked less and felt more motivated to quit, but overall, IQOS has not been proven to help people stop smoking completely.¹²³⁶⁷
