  • Some of the flavourings used in vapes may be harmful to a developing baby.
  • Fetal exposure to nicotine during pregnancy can result in multiple adverse consequences, including sudden infant death syndrome, altered corpus callosum, auditory processing deficits, effects on behaviours and obesity, and deficits in attention and cognition (CDC, 2016)
