Earlier this week, a man shared a 'before and after' photograph showing how much he has changed since giving up meth.
Ryan Harder, 23, said he'd stopped taking the drug methamphetamine almost one year ago and wanted to highlight to others just how much can change in that time.
After he posted the brave snapshot on Reddit, the man received hundreds of supportive messages from the online community.
He has since inspired others to share their own photographs of how far they've come since quitting drugs.
"I quit meth almost a year ago. It's crazy how much can change."
Harder started taking drugs when he was 14. Over the years - and after being arrested several times - he realised he needed to give them up.
But despite trying 10 different treatment programs to try and get clean, he couldn't. It was then that Harder, aged 18, became addicted to meth - and his life took a turn for the worse.
"I was going to jump off the bridge because I’d had enough of the lifestyle of being high, being homeless, having nowhere to go and being completely unhappy," he said.
It was this make or break moment which helped Harder get on the road to recovery.
After nine months of being clean, he posted a before and after photo on Reddit showing his achievements. The photograph went viral and has since been viewed more than 2.5 million times.
Since Harder's brave post, another photograph has surfaced online showing a woman, who used to be addicted to meth, after 90 days of being clean.
The photograph was shared by the woman's brother who said he'd been "inspired" by Harder's actions. It has now been viewed more than one million times.
The guy who uploaded it said that when his sister was taking meth she would lie, steal and take advantage of their family in order to get a fix.
He added that his sister wouldn't listen to family members who told her she needed to get help, instead she had to find out for herself.
Others have also jumped at the chance to share their stories and photographs since getting clean.
Methamphetamine is a highly addictive stimulant that affects the central nervous system. It takes the form of a white, odourless, crystalline powder that easily dissolves in water or alcohol.
According to the National Institute on Drug Abuse, meth addicts can be prone to anxiety, confusion, insomnia, mood disturbances and violent behaviour.
They also may display a number of psychotic features including paranoia, hallucinations and delusions.
