Which sign could indicate a decline in personal grooming due to substance abuse?

A decline in personal grooming can be a significant sign of substance abuse, and unusual smells on breath, body, or clothing are particularly indicative of this issue. When someone is using substances, they may neglect their personal hygiene due to altered priorities or the effects of the drugs themselves. For instance, certain substances can lead to a lack of motivation or focus, which may result in a person not bathing regularly or changing clothes as often as they should. The presence of unusual odors can also be a direct consequence of the substances consumed, as these can linger on the body or clothing and contribute to an overall neglected appearance.

In contrast, frequent showering, increased grooming habits, and a consistent appearance of clean clothes typically suggest that a person is maintaining their hygiene and is less likely to be experiencing significant personal decline. Thus, these indicators are unlikely to align with the signs of substance abuse, highlighting why the presence of unusual smells is a more telling sign of potential issues with personal grooming in the context of substance use.
