The document discusses two public health campaigns - the NHS Smoking campaign and the Think! Drink Driving campaign. The NHS Smoking campaign aims to educate people about the health risks of smoking and help smokers quit. It provides resources like a website with real stories of ex-smokers and calculators showing money saved from quitting. The Think! Drink Driving campaign similarly aims to increase awareness of the legal and safety risks of drink driving to discourage it, especially among young men. Both campaigns use websites, posters, and videos to convey their important health and safety messages.
