Substance use impairs performance and safety. When someone uses drugs or alcohol, their coordination, balance, vision, reaction time, and judgment are reduced. That makes it much easier to make errors, miss warning signs, or react too slowly in hazardous situations. In a work setting, this translated impairment leads to a higher likelihood of accidents and injuries for the user and those nearby. The other options don’t fit because substances don’t typically improve performance or leave behavior unchanged, and the impairment usually shows up as increased risk rather than no change.
