> it absolutely is a habit

You can follow the definition that you like, but the typical habit is something you just do without thinking. Taking drugs is mostly something you do to get the kick and in later stages because you don't want the withdrawal symptoms. Some addictions are quite habitual too (smoking is not just for the nicotin but also having the habit of taking a break for 10 minutes out on the balcony), but arguably there is more to an addiction than the habit component which is only a minor contributor if at all.
