“…Nearly 100 million people use waterpipe on a daily basis (Wolfram et al, 2003); and this form of smoking causes approximately 5 million deaths per annum (Neergaard et al, 2007). WS is a cultural custom in many Middle-Eastern countries including Bahrain, Egypt, Jordan, Qatar, Saudi Arabia, Syria, Turkey, Lebanon, and the United Arab Emirates (Natto, 2005, Moh’d Al-Mulla et al, 2008, Maziak et al, 2009, Borgan et al, 2014, Jaghbir et al, 2014, Almutairi, 2015, Maziak et al, 2015a, Javed et al, 2016a); However, this form of tobacco smoking has gained popularity in many other countries including Canada, Denmark, Greece, India, Pakistan, Malaysia, Sweden, United Kingdom and the United States (U.S.) (Jensen et al, 2010, Kassim et al, 2014, Ramji et al, 2015, Hammal et al, 2016, Sidani et al, 2016). In the U.S., the Tobacco Products and Risk Perceptions Surveys of 2014 and 2015 found a prevalence of 15.8% of ever smoking waterpipe among adults (Majeed et al, 2017).…”
