An addiction is defined as the inability to stop some sort of activity or behaviour, even if it is causing physical or psychological harm. A simple addiction, like needing a coffee first thing in the morning, is generally regarded as being normal – even though it’s a sign that the body is lacking in energy. But if you can’t live without it, it’s still an addiction. More damaging and serious addictions, like alcohol, drugs, gambling, or pornography, cause terrible damage to the user, their family, and their community.
