The horrifying effect that drugs can have on addicts has been highlighted in a series of disturbing pictures and video.
The campaign, launched by Rehabs.com, uses photographs which show American drug users in various stages of addiction.

These include:
A 2012 study found that 4.5 million Americans were dependent on illicit drugs, and millions more had used illegal drugs in the month before the study.
Rehabs.com aimed to raise awareness about what can stem from the more casual use of drugs.
"Use of these dangerous drugs can easily lead to addiction," they wrote.
