Which BAC range corresponds to the euphoria stage?

• A. 0.01-0.05%
• B. 0.03-0.12%
• C. 0.18-0.30%
• D. >0.45%

Answer: (B)

The euphoria stage appears when blood alcohol concentration is in the roughly 0.03% to 0.12% range. At these levels, the central nervous system is dampened enough to lift mood and reduce inhibitions, so people often feel more relaxed, sociable, and confident. You may notice talkativeness and a sense of well-being, but coordination and judgment are already beginning to decline, which fits the way this stage is described.

Lower ranges like 0.01–0.05% involve milder, early effects such as slight relaxation rather than full euphoria, while higher ranges such as 0.18–0.30% correspond to significant impairment and stupor, and above 0.45% is associated with danger and possible coma.
