Man’s penchant for getting drunk is much older than keeping himself clean. I mean the use of alcohol and other substances obtained from plants which give high is much older than the invention of soap for cleaning the body.
But it is not only the humans who feel the need to get a high but many animals also are similar. Johann Hari, who is the author of book “Chasing the Scream: The First and Last Days of the War on Drugs” has spent 25 years observing the behaviour of animals when they are alarmed or in grief. He began his research after going through the findings on this subject by Ronald Siegel. For example, Siegel had planted “Silver Morning Glory” a plant containing powerful hallucinating chemicals in a pen of Hawaiian mongoose. The when tasted it leaves felt disoriented and avoided the plant altogether. But there happened a tropical storm which destroyed the den, filled it with mud and left the female dead. The male returned to the plant and ate its leaves to get blasted out of mind. After that Hari began his research and found more evidence. For example, in Vietnam, he found that prior to bombings in the Vietnam war with America, the buffaloes never chewed on opium plants. But when the bombings began, the water buffaloes ate the opium plants. They became dull and dizzy to escape their thoughts like mongoose. Similarly, bees fell to ground in a temporary stupor after sampling the numbing nectar of certain orchids. Birds gorge themselves on inebriating berries, then fly with reckless abandon. His more observations are given below : “Cats eagerly sniff aromatic “pleasure” plants, then play with imaginary objects. Cows that browse special range weeds will twitch, shake, and stumble back to the plants for more. Elephants purposely get drunk off fermented fruits. Snacks of “magic mushrooms” cause monkeys to sit with their heads in their hands in a posture reminiscent of Rodin’s Thinker. The pursuit of intoxication by animals seems as purposeless as it is passionate”
