Air India and Air India Express will screen all their pilots for psychoactive substances after the commander of a Phuket-Delhi flight tested positive for marijuana, news agency PTI reported on Thursday, citing sources.

The two Tata Group-owned airlines have more than 5,000 pilots between them. The mandatory screening will begin on Thursday.

In an internal message to pilots, the airlines said they would carry out a full screening for substances or medications not permitted under prevailing regulations.
