1. Isolation : Addiction may cause a person to withdraw from loved ones or may cause others to drift away from them. They may find themselves ostracised from society.
2. bad decisions : If a person's life becomes driven by the addiction, this dependence may influence their decision making and cause them to make choices and sacrifices they may come to regret.
3. dependence, in general: An addict to anything will find their freedom restricted by the addiction... to depend on any one thing in order to function will have this effect. It is unhealthy and may lead to other problems such as depression.
