A Missouri mom has shared photos showing the toll drugs have taken on her son — turning the once-strapping young man into a scarily emaciated addict in just seven months.

“The face of heroin and meth,” Jennifer Salfen-Tracy wrote on Facebook alongside two shots highlighting the horrifying transformation of her son Cody Bishop, who is now homeless in Las Vegas.

“These pictures were taken 7 months apart. That is how fast someone is affected.”

Calling it a sad “reality for so many people and families,” the mom from Wentzville admitted it is a “heartache” she has previously kept hidden.

But she decided to share it in a call for action — and the post has since gone viral and shared 45,000 times.

“This is a true issue in our world today that we need to pull together and focus on to fix instead of the government worrying about and spending all their money on throwing each other under the bus,” she wrote.

“This is not just a problem that my family faces but almost everyone knows someone who has a drug/heroin addiction.”

Salfen-Tracy said she had not heard from her eldest son in weeks.

“Hearing how bad he is doing is hard but not hearing at all is worse,” she wrote. “Cody if you see this please call us … we love you!”
