Erin O'Hara: What effect does nicotine have on the body?

The Sunday Session with Francesca Rudkin

The Government is suggesting limiting the amount of nicotine allowed in cigarettes.
It is one of a number of proposals being put forward to meet its goal of making New Zealand smoke-free by 2025.
Others include restricting where cigarettes can be sold and creating a licensing regime.
The Government is also talking about creating a smoke-free generation, where people who are under 18 next year will never be able to buy cigarettes.
Wellbeing and health expert Erin O'Hara joined Francesca Rudkin to discuss what nicotine does to the human body.
