Since alcohol is a depressant in that it reduces pain, many individuals use it as a way of release or escape. It can feel like a comfort to many people to have that release from the daily stresses of life. However by doing so, some people can feel the only way to be happy is under the influence of alcohol. The brain associates happiness with drinking by as process of classical conditioning and can this be extremely detrimental.
As a result, this can cause levels of instability and feelings of depression. The more it becomes a habit, the harder it is to break this habit and it turns into a vicious cycle. However, with the alcohol alternatives tasting as close to the real drink, many people can experience a placebo effect. Individuals can feel that same happiness they felt previously, without having the after effects.
This is not to say that non-alcoholic drinks can cure addiction, but more of an example of how they could be utilised in the future.
