Signs and symptoms of alcohol poisoning include:

  • Confusion, stupor
  • Vomiting
  • Seizures
  • Slow or irregular breathing (fewer than 8 breaths / min or more than 10 seconds between breaths)
  • Blue-tinged skin or pale skin
  • Low body temperature (hypothermia)
  • Unconsciousness ("passing out") – person can not be roused with loud noises or painful stimuli (pinching or sternum rub)

It's not necessary for all of these symptoms to be present before seeking help.  The only thing that reverses the effects of alcohol is time-something you may not have if you or your friend is suffering from alcohol poisoning.
