I think that is what is being said. Effexor is not addictive in the ‘traditional’ sense addictive drugs are, but you’re brain and body become dependent on them in ways you don’t realize until you’re trying to come off of them. And because it is a process to find the right medication, you don’t want to be starting and stopping those kinds of medications over and over. A stimulant may be seen as more addictive (due to the potential for abuse / dopamine release), but starting Ritalin then switching to adderall, then say vyvanse, is a less invasive process than starting Effexor then coming off and switching to Wellbutrin etc
