title_body: Coffee consuming amount
upvoted_answer: Prevailing wisdom is that it is generally safe to drink up to 4 cups of coffee per day. Caffeine is the world's most widely consumed psychoactive drug (stimulant) and typical consumption is alleged to have a number of positive health benefits.
  
  The U.S. 2015 Dietary Guidelines Advisory Committee recommended a similar limit. Lower limits are recommended for pregnant women, adolescents &amp; children.
  
  Lethal caffeine overdoses are rare and estimates of a lethal amount of caffeine in a healthy adult range from 10,000 - 20,000 mg.
