According to this, habit is:
“The Merriam-Webster dictionary defines a habit1 as ”an acquired mode of behavior that has become nearly or completely involuntary.” In some contexts, the word habit can appear synonymous with addiction, but they differ quite drastically. Swapping one for the other can inadvertently cloud the truth of an addiction and the effects it can have.
Examples of habits include:
Having a cup of coffee in the morning
Talking evening walks
Reading before bed
Meditating
Making your bed
If needed, you can choose to not do a habit. Though doing it may come instinctually, you could stop with some conscious effort. Even if it feels a bit weird or uncomfortable, it doesn’t cause physical withdrawal symptoms or consume your thoughts. ”
Now compare that to what we are talking about. Taking Antidepressants or Antipsychotics is not an acquired mode of behavior. They are chemical mixtures that were prescribed. They are not involuntary (or nearly so). You have to remember to take them. But the biggest difference here is the last sentence about breaking a habit: Even if it feels a bit weird or uncomfortable, it doesn’t cause physical withdrawal symptoms or consume your thoughts.
We’ve already seen medical evidence showing that stopping SSRIs can result in symptoms that closely resemble those of stopping heroin. Another interesting sentence in this is the one that states swapping “habit” in place of “addiction” can inadvertently cloud the truth of an addiction and the effects it can have.
Just because it is a prescribed drug doesn’t mean it can’t cause an addiction. We’ve seen that too many times with the opioid crisis in this country. To look at addiction, this same article has this interesting line in it:
_“Addiction primarily differs from a habit in that stopping has consequences. Many people who try to stop experience withdrawals, which are physical and mental reactions to not having the substance3.”
Since we know that just stopping antidepressants can have physical and mental reactions, I’d suggest they fall closer to addiction.
