It is well established that smoking can damage your health. Nonetheless, around one third of the Irish population continue to smoke. Irish research (Brugha et al. 2009) suggests that most smokers want to give up and half will have tried in the last year but nicotine is a notoriously addictive substance. One measure of its addictiveness can be gleaned from the fact that around 18% of pregnant women smoke at some point during their pregnancy and 13% continue to smoke right through.
