Its common knowledge that cocaine is an extremely addictive substance. Yet for years after it was first discovered in 1855, it was glorified as a magic potion. Sigmund Freud, the father of psychoanalysis, recommended it. Inventor Thomas Edison and actress Sarah Bernhardt promoted it. John Pemberton, who created Coke, included it in his original soft drink recipe. Not until 1920 was it outlawed by the federal government.
Today, we recognize the highly addictive nature of cocaine and other drugs, as well as cigarettes and alcohol. And we've learned that in addition to substances, certain activities, such as sex and gambling, can become addictions for some people, ruling and ruining their lives.
