Vaping with a child in the car soon will be illegal in Louisiana. Louisiana law already prohibited drivers and passengers from smoking cigarettes, pipes or cigars if a child’s in the vehicle. A bill by Gretna representative Joe Marino adds vaping to that list. Governor John Bel Edwards announced Tuesday that he signed the measure into law. The house voted 80-to-19 for the measure in the regular session that ended June 1st, while the 30 senators voted unanimously in approval. The new prohibition takes effect in August.
