Is your family suffering by your substance abuse issue? Do you have anxiety, depression or suicidal thoughts? If yes, then you have to get rid of this habit immediately. Take regular days off from alcohol and drugs to ensure you are not addicted to it. You can also take expert advice and guidance to get rid of the addiction. Some addiction treatment centers like Edgewood in Toronto are providing self-assessment tests and programs for checking the addictive nature of a person.
