Prevalence and reasons for use of heated tobacco products among Malaysian adults who smoked: Findings from the 2020 International Tobacco Control Malaysia Survey

There have been rapid expansions in heated tobacco products (HTPs) outside of Japan and the Republic of Korea. In November 2018, HTPs were first introduced in Malaysia and since then, no studies have been conducted on Malaysians’ use of HTPs. This study is the first to examine the prevalence of HTP use and reasons for use among Malaysian adults who smoked cigarettes. Data came from the 2020 ITC Malaysia Survey, a web-based survey of a nationally representative sample of adults who smoked (n=1047) aged 18 and older. They were asked on ever heard of, ever used, and currently using HTPs, and their reasons for using HTPs. Overall, 25.4% (n= 324; 95% CI:22.3%−28.7%) of Malaysians who smoked reported ever used HTPs with 6.7% (n=85; 95% CI:22.3%−28.7%) were using them daily and 8.1% (n=110; 95% CI:6.4% −10.2%) were using HTPs non-daily. Most of them (57.2%) who dual use were of aged 25–39 and 97.3% were males. Among those who smoked daily, almost half (49.3%) were also using HTP daily. Among those who used HTPs daily and non-daily, curiosity (84.2%, 95% CI:78.4%−90.0%), taste (83.2%, 95% CI:77.3%−89.1%), and appealing technology (78.5%, 95% CI:71.3%−85.6%) were the most reported reasons. Among those who used HTPs daily, curiosity was the top reason (87.9%, 95% CI:78.9%−93.4%), while among non-daily, taste good was the top reason (81.9%, 95% CI:71.9%−88.8%). The very high use of HTPs among Malaysians who smoked requires continued public health surveillance that can inform the regulation of these novel tobacco products. •A quarter of Malaysian adults who smoke ever used HTPs and 14.8% currently used HTPs.•Among Malaysian adults who smoke, current HTP use was most common among people ages 25–39 and adults having a Bachelor’s degree or higher.•Malaysian adults who smoked daily were more likely to use HTPs than those who did not smoke daily.•Among people using HTPs, the main reasons for use were curiosity and taste.
