Teen With Brain Damage After Taking Ecstasy Posts Tragic 'Thank You' Video For Loved Ones

"Tell your children, family and friends."

Amy Thomson didn't think one tiny pill could change her life forever, but it did. 

Thomson took one dose of pure MDMA this June, otherwise known as Ecstasy, which is believed to have put the 16-year-old UK resident in a two-week coma. When she woke up, she had brain damage. 

Her family didn't believe a drug so small would turn Amy's and their lives upside down, but now they're using a Support for Amy Facebook page to give updates on her and spread awareness. A friend of hers runs the page that has racked up more than 4,500 likes.

This week, she posted a video of Amy in her wheelchair, thanking her friends for the outpouring love and support.

"Thanks everyone thanks for your support everyone," she says in the video.

After the video went viral, the person behind the page took the time to post a status, asserting the video was a thank you, not a warning. 

"Amy's video wasn't intended to send a message to anyone. She wanted to thank all of the people who wished her well," they wrote. 

But the post did not end there. They took the time to address the "trolls" leaving comments on the video, defending the drug.

"What upsets me is the fools who appear and do their best to defend MDMA as though they know what they're talking about. How do they know it is safe? Where do they come from? Are they there when these drugs are being produced? Unlikely," they wrote. 

They explain that Amy's pill was uncut, confirmed by the doctor.

"This wasn't an isolated incident. Amys three friends were kept in hospital that night and while she was in ICU, another young lad was brought in from the other end if the city."

"He too has a brain injury."

MDMA is an illegal drug for a reason. Though it's known for it's feel-good, hallucinogenic effects, the side effects (as seen by Amy) can be detrimental. 

According to the government drug database, side effects include seizures, unconsciousness, heart and kidney failure, among others. 

Her loved ones just want people to know it can happen to anyone. 

"Tell your children, family and friends. You think it won't happen to you? So did we."
