To claim that these casual users function perfectly within society is borderline ridiculous.
I would state it as a fact that casual users are able to function perfectly within society. That is not to say there aren’t long term health effects as a consequence of drug use.
I think you’re referring to users that transition from casual to frequent. While casual users can and do accidentally overdose or have a bad reaction leading to an emergency room visit, this wouldn’t impact their ability to function in society overall. Frequent visits to the emergency department would suggest a frequent user and likely one that is increasingly unable to function normally in society.
