Monitoring website marketing among leading e-cigarette brands and vendors in California: content analysis.

Background: Electronic cigarette (e-cigarette) brands and vendors use websites to promote pro-tobacco messages that may increase susceptibility to use e-cigarettes among never users or help sustain continued e-cigarette use among current users. E-cigarette website marketing is lightly regulated, and little is known about promotional strategies used on e-cigarette companies' websites. This study conducted a content analysis of website marketing from leading e-cigarette companies selling products in California.

Characteristics of flavored and non-flavored waterpipe tobacco users: a real-world setting study.

We aimed to compare sociodemographic characteristics, smoking patterns, beliefs and perceptions, nicotine dependence, and psychological indicators between flavored waterpipe (WP) tobacco (FWT) and non-flavored WP tobacco (non-FWT) smokers in Iran. A cross-sectional study was conducted in 94 WP-serving venues surrounding Tehran and Ardabil metropolitans in Iran. Convenience sampling was applied to select 900 current WP smokers [508 (56%) FWT-only and 392 (44%) non-FWT-only smokers] aged 18 years and older.
