Body mass (g) over the first three postnatal days in animals that were born to dams that were surgically implanted with osmotic mini-pumps, loaded to deliver either saline or nicotine

Postnatal age (days)	Saline exposed	Nicotine exposed	Control
1	6.7 ± 0.6	6.9 ± 0.3	7.1 ± 0.2
2	8.0 ± 0.5*	8.0 ± 0.3*	7.8 ± 0.2*
3	9.1 ± 0.7*	8.8 ± 0.4*	8.6 ± 0.3*

The control animals were born to dams that did not undergo any surgical interventions. Data are the mean ± 1 s.e.m.

^*P < 0.05 compared to postnatal day 1. There were no significant differences in growth between the three groups.
