A mum has shared a picture of her teenaged son who overdosed on heroin in an attempt to raise awareness of drug addiction.

The before and after image of 18-year-old Brayden Travis has gone viral after Kelly Smith-Miller posted it on Facebook along with a warning to parents.

“I share this with each of you in hopes that you won’t feel pity or be offended, but rather share and get these pictures in front of your teenagers, she writes.

“Don’t be scared to share the horrific outcome of what most likely will happen when using heroin! It’s not the only drug that will kill you either.”

Kelly says her son has struggled with drug addiction since he was 15 years old. He went into a coma after he OD. She described the incident on Facebook alongside the image.

Doctors have reported Brayden is now awake and breathing on his own although he suffered a stroke and now has severe brain damage.

Do you think sharing this image will help warn teenagers away from drugs?
