Why do I always smell after drinking?
Why do I always smell after drinking? Body odour is an inevitable side effect of alcohol consumption, whether casual drinking or drinking alcohol excessively. Alcohol detoxification causes a strong odour due to excess sweating and expelling toxins. Alcohol-related diseases such as liver disease, kidney disease, and diabetes cause body odour.
How much alcohol does it take to smell on your breath?
At BACs of 0.08% and below, the probability appears close to 60%, but for BACs above 0.08% the probability rises to the 80% range when no food odors are present. Under more realistic field conditions, the probability of detecting alcohol odor would be much lower.
