When you smoke you inhale over 4000 chemicals.

That's the straight up message to be carried in ads that will start on Sunday and run nationwide for more than three months, Health Minister Nicola Roxon said.

"While smoking prevalence in Australia has declined over time, rates of daily smoking remain too high at 16.6 per cent of those aged 14 or older," Ms Roxon said on Saturday.

"The 2010 stage of the National Tobacco Campaign will reach a broad age-range, but focuses on young adults."

Ms Roxon said at least 43 of the 4000 chemicals can cause cancer.
