Let’s recap by doing the calculations again - for all three:
WHISKEY THAT CONTAINS 50% ALCOHOL (100 PROOF)
(1 OZ. multiplied by .50 = .50 OZ. (amount of PURE ALCOHOL in the 1 oz. shot or jigger)
BEER - 4% to 5% ALCOHOL
(12 OZ. multiplied by .04 = .48 OZ. (amount of PURE ALCOHOL in a 12 oz. beer)
WINE - 12% to 15% ALCOHOL
(4 OZ. multiplied by .12 = .48 OZ. (amount of PURE ALCOHOL in a 4 oz. glass of wine)
Conclusion: They all contain approximately the same amount of alcohol....
Early Spanish explorers noticed how the native people of South America were able to fight off fatigue by chewing on coca leaves. A medical account of the coca plant was published in 1569. In 1860, Albert Neiman isolated cocaine from the coca leaf and described the anesthetic action of the drug when it was put on his tongue. Angelo Mariani, in the early 1880s produced a "medicinal" wine, called Vin Mariani, that contained 11% alcohol and 6.5 mg of cocaine in every ounce. The famous psychotherapist, Sigmund Freud, in 1884, recommended cocaine for a variety of illnesses and for alcohol and morphine addictions. Unfortunately, many of his patients went on to become addicted to cocaine! In 1886, John Pemberton developed Coca Cola, a drink that contained cocaine and caffeine. Cocaine was REMOVED from Coca Cola in 1906 (but it still has the caffeine). The Harrison Narcotic Act in 1914 made cocaine illegal.
