Facebook-owned Instagram is rolling out a new "prompt feature" that would pop-up if users try to find substance abuse related recovery and treatment services or look to buy drugs illegally on the platform using certain hashtags such as "opioid", the media has reported.

"Instagram says people are using hashtags to find addiction support and communities as well as illegal drugs. This prompt is an attempt to help people who are indulging in or fighting against addictions like opioid and other drugs," The Verge reported late on Wednesday.
