The question is: “Are addictions actually bad habits?” According to the habit model of addiction, they are. This theory of addiction states that the only reason to say there is a difference is to persecute “addicts.”
People with bad habits of smoking often feel much persecuted. While smoking is not illegal (at least not yet), it is shunned by society as a whole. At first, you could smoke anywhere. Expecting fathers smoked in the maternity waiting rooms. Then, you could smoke in buildings, but only in a designated smoking room.
