Understanding Public Perceptions and Misconceptions of Water Pipe Smoking: Implications for Cardiovascular Health Education and Policy Reform

Abstract

Water pipe smoking is believed to be less harmful than cigarette smoking, stemming from the unique design and operation of the device. Water pipe smoking, also known as hookah, shisha, or narghile, has gained global popularity, particularly among adolescents and young adults. Our paper examines public perceptions, misconceptions, and cardiovascular health risks associated with waterpipe smoking, synthesizing findings from 96 peer-reviewed studies published between 2000 and 2024. This review adopted a narrative design to bridge existing research gaps by synthesising and contextualising diverse findings. Most studies (52%) were observational, with 67% focusing on Middle Eastern and South Asian populations. Evidence reveals widespread misconceptions about the safety of water pipe smoking, driven by its cultural acceptability, social nature, and the belief that water filtration reduces harm. However, research demonstrates that water pipe smoking exposes users to high levels of toxic substances, including carbon monoxide, nicotine, heavy metals, and carcinogens, comparable to or exceeding cigarette smoking. These substances increase the risk of cardiovascular diseases such as atherosclerosis, myocardial infarction, and hypertension. The social context, flavored tobacco, and targeted marketing have further normalized water pipe smoking, particularly in low- and middle-income countries (LMICs) where regulatory oversight is minimal. Public health efforts to address water pipe smoking remain limited, exacerbating its cardiovascular health burden. The prevalence of water pipe smoking and associated perceptions varied significantly by region and demographic group. Studies from the Middle East and South Asia reported a pooled prevalence of 27% (95% CI: 23%-31%), highlighting cultural entrenchment and widespread misconceptions. A meta-analysis of 24 studies (n=18,500 participants) revealed that 72% (95% CI: 68%-76%) of users believed the water filtration process reduced toxic substance intake, including nicotine, tar, and heavy metals. Meta-regression analysis of pooled data from 21 experimental studies showed a significant increase in heart rate (12%, 95% CI: 10%-14%) and systolic blood pressure (7 mmHg, 95% CI: 5-9 mmHg) following a single session of waterpipe smoking. This review emphasizes the need for culturally tailored interventions, comprehensive public health campaigns, and stringent regulatory measures to address misconceptions and reduce water pipe smoking prevalence. Future research should focus on the long-term cardiovascular impacts, dual tobacco use, and effective policy strategies. Healthcare providers and policymakers can mitigate the significant cardiovascular risks of water pipe smoking globally by addressing these gaps. A collaborative effort between policymakers, healthcare professionals, and community leaders is essential to curb the growing public health challenge posed by water pipe smoking. By taking these immediate steps, we can pave the way for stronger policy frameworks, increased public awareness, and ultimately, a reduction in smoking-related cardiovascular diseases.
