PARIS — French lawmakers have adopted a bill banning children under 15 from using social media, making France the first country in the European Union to approve a blanket ban on platforms as concerns grow worldwide over the harmful effects of digital content on kids.

Both chambers of the Parliament voted Tuesday in favor of the measure, a flagship initiative of French President Emmanuel Macron’s second term. The bill also bans the use of mobile phones in high schools.

The legislation is one of the final major measures adopted under his presidency before he leaves office next year. Macron wants the law to take effect at the start of the new school year in September. However, a review to determine whether the bill complies with the French Constitution is likely to take place and could delay its implementation.
