Hookah Smoke Exposure for Secondhand Smoke Effects

Q: What is the current number of participants in this research?

Yes, the clinicaltrial.gov database indicates that this research trial is still actively seeking participants. Initially posted on June 25th 2021 and last updated on September 1st 2022, the study requires 12 individuals to join from a single site.

Q: Is the age cutoff for acceptance into this trial above 35 years?

This trial is only open to participants that are between 21 and 49 years old. For other age groups, 8 studies exist for individuals under 18 and 11 studies are available for those above 65.

Q: Is there any availability left for volunteer participants in this research effort?

Affirmative. The trial is open for applications, as evidenced by the data posted on clinicaltrials.gov from June 25th 2021 and updated September 1st 2022. This medical research requires 12 participants to be recruited from a single hospital or clinic.

Q: Who would be an optimal candidate for this clinical trial?

This medical trial is looking to recruit a dozen individuals aged 21-49 who partake in waterpipe <a href="https://www.withpower.com/clinical-trials/smoking">smoking</a>. To be eligible, participants must possess no prior history of tobacco use and not have been exposed to environmental tobacco smoke for at least one week leading up to the study date. Furthermore, they should not suffer from cardiopulmonary disease or take any prescription medications. Eligible candidates will also need to show that their blood pressure is below 140/90 mmHg and resting heart rate measures &#x3C;100 bpm with BMI >18 or &#x3C;- 30kg•m2

Study Summary

This trial will study the effects of secondhand exposure to electronic hookah smoke on blood pressure and blood flow.

Who is the study for?

This trial is for non-smokers aged 21-49 with no recent secondhand smoke exposure, not on prescription meds, and without heart or lung disease. Participants must have a resting heart rate below 100 bpm, blood pressure under 140/90 mmHg, and a BMI between 18 and 30. Pregnant or breastfeeding individuals can't join.Check my eligibility

What is being tested?

The study investigates the immediate effects of secondhand hookah smoke and e-hookah aerosol on blood vessel function compared to clean air. Volunteers will undergo three sessions where their blood pressure and flow are measured before and after exposure to each condition.See study design

What are the potential side effects?

While specific side effects aren't listed for this observational study, potential risks may include temporary increases in blood pressure or changes in vascular stiffness due to inhalation of hookah smoke or aerosol.

Experimental Treatment

Group I: Exposure to Electronic Hookah AerosolExperimental Treatment1 Intervention

Participants will be exposed to electronic hookah aerosol. To mitigate the impact of carryover effects, the exposure sessions will be separated by a minimum of 7-days.

Group II: Exposure to Combustible Hookah SmokeExperimental Treatment1 Intervention

Participants will be exposed to combustible hookah smoke. To mitigate the impact of carryover effects, the exposure sessions will be separated by a minimum of 7-days.

Group III: Exposure to Clean AirExperimental Treatment1 Intervention

Participants will be exposed to Clean Room Air. To mitigate the impact of carryover effects, the exposure sessions will be separated by a minimum of 7-days.
