Background
ADVERSE EFFECTS
Alcohol drinking and tobacco smoking can have cumulative adverse effects on health [Given this evidence, brief alcohol interventions (BAIs) to stop or reduce alcohol risk drinking might have the potential to reduce tobacco smoking, even if not primarily aimed at. BAIs have been shown to reduce alcohol use in health care populations [Most of the BAIs investigated with regards to spill-over effects were delivered in-person [The two aims of this study were, first, to investigate whether computer-based and in-person delivered BAIs may reduce tobacco smoking over two years and, second, whether such an effect differs by delivery mode, that is whether in-person or computer-based BAIs are more or less effective in also reducing tobacco smoking.
