TikTok has been forced to remove some videos on its platform that appeared to be promoting the use of "diet pills".
Teenagers using the social media app who search for that term have been shown "dangerous" information, including the promotion of epilepsy drugs said to aid weight loss.
The Pharmaceutical Journal launched an investigation and analysed the top 100 popular user posts under the hashtag #dietpills - finding that a number were advocating the use of prescription-only medicines for conditions including epilepsy, alcohol addiction and migraines.
