Which of the following is NOT a sign of a potential substance abuse problem?

A sudden change in personality or demeanor, slurred speech along with looks of fatigue, and unusual anxiety or suspicion around friends are all indicators that could point to potential substance abuse. These signs reflect shifts in behavior that are often associated with the effects of drugs or alcohol, as individuals may struggle to maintain their usual personality or might develop physical symptoms that draw attention to their possible substance use.

In contrast, being really into a new hobby and frequently discussing it does not typically correlate with signs of substance abuse. This behavior can be associated with normal enthusiasm and passion for an activity, which does not suggest an underlying issue with drugs or alcohol. It’s common for individuals to immerse themselves in hobbies for a variety of reasons, including stress relief or personal fulfillment, which does not indicate potential abuse of substances. Thus, this option stands out as unrelated to substance abuse concerns.
