Many people who fall victim to drug addiction at some point in their lives find they feel as if they have nobody to talk to about their issues.
The stigma attached to becoming dependent on illegal substances such as heroin and cocaine means many people who are affected by these very real issues are left isolated and fall deeper into their addiction because they feel there is no solution.
In many cases, individuals who are accustomed to hiding their drug addiction from friends and family members keep the habit a secret for several years until the physical effects of dependency become too obvious to hide.
This is why getting help for problems involving illegal substances is vital for bringing about a recovery that could see those affected conquer their demons and grow into a better person rather than suffering in silence.
Many people who have been affected by addiction in their adult life find their solace in talking to other individuals who have battled similar demons, as it means they can help to prevent others going along the same path of destruction as they have.
This is certainly the case for former Friends actor Matthew Perry, who recently revealed he has found "meaning" in his life by guiding drug addicts on their road to recovery.
The 43-year-old, who played Chandler Bing in the popular TV sit-com for ten years, previously battled his own addiction to prescription tablets for several years.
He said: "My life has a lot more meaning now that I try to help people … It’s also a selfish thing - it makes you feel better than anything else will."
Perry also claimed his past demons stopped him from following his dream of being elected as US president, claiming he has been to rehab too many times to run for office.
However, the actor - who has carried out stints in rehabilitation centres on three occasions - spoke about his aim to change lives during a speech in Washington as he campaigned to support specialist drug courts to deal with drug addicts.
The star told officials at the House Appropriations Subcommittee on Commerce, Justice, Science and Related Agencies such legal proceedings are the "single most effective programme for curing serious drug addicts for life-long recovery".
He added: "I do jump at any opportunity to come here and talk about (drug courts)… Any opportunity I get to talk about drug courts on a one-on-one level or a much bigger level - like testifying in that scary room - I grab at because it’s just one of the few things that’s a no-brainer: it saves lives, it saves money, it’s bipartisan."
The comedy actor also opened up about his own battle with drug addiction following the end of filming for Friends in 2004, previously telling Oprah Winfrey his treatment had very little to do with courage.
He said his recovery, which saw him last check into rehab two years ago, came about as a result of him accepting it was a "life or death" situation - stating that he had to "surrender" and realise he needed help.
