Previous analyses have focused on women smokers. “In fact, smoking in fathers-to-be and exposure to passive smoking in pregnant women are additional common than smoking in pregnant women,” Qin said.

“Doctors and primary healthcare professionals need to do more to publicize and educate prospective parents about the potential hazards of smoking for their unborn child,” said Qin.
