What is the effect of the blood alcohol level on behavior?

• 50 mg/dL - flushed skin, more talkative, loss of emotional restraint, feeling of warmth, mild impairment of judgment
• 100 mg/dL - reduced reaction time and coordination (e.g., writing, driving), slowed thinking, inappropriate laughter, mildly slurred speech
• 200 mg/dL - unsteady or staggering gait, sleepy but arousable by voice, difficulty sitting up straight in a chair, very slurred speech
• 300 mg/dL - stuporous and arousable only by physical means (e.g., slapping face, forceful pinching), loud snoring
• 400 mg/dL - coma, incontinence of urine
• 500 mg/dL - death
• Alcoholics develop tolerance and may show less physical effects at any alcohol level.
