Stacey Dooley goes undercover in the growing criminal world of Britain’s digital drug dealers. Using fake profiles on Instagram, Snapchat and the new ‘Tinder for Teens’ app Yellow, she reveals how easy it is for children and young teens to get their hands on Class A drugs via seemingly unmoderated and unprotected social media platforms. By decoding a little-known-about secret drug code that's reliant on emoji symbols to hide what's being said, Stacey is able to meet and confront face to face these digital dealers, with one of them admitting to her he is only 15 years old. Stacey then gains access to the gang leaders’ of one of Britain’s largest drug outfits, who rely upon these social media savvy youngsters to push their illegal business through the popular teen apps. They reveal to Stacey that approximately two-thirds of their trade now comes through social media transactions and the fast paced communication style of these platforms means they can sell up to £22,000 worth of cocaine in only a couple of hours. As this downloadable danger gathers pace, recreational drugs and recreational apps are on a collision course. Stacey asks are these global social media giants doing anything to tackle this illegal trade on their servers and protect the millions of young people and children all across the country who spend hours on these platforms every day.
