Twitter fails to take down Xanax adverts
Twitter and Instagram have been criticised by an MP for failing to remove posts advertising Xanax.
There is evidence the anti-anxiety medication is increasingly being used recreationally by young people, some of whom have needed hospital treatment.
Xanax's manufacturer Pfizer said anyone buying it on social media will be buying fakes.
Twitter said the adverts were organic content created by users rather than being official advertising.
