There would be one notable and significant invention I would aim to prevent, if it was possible for me to travel back in time to do so. The invention I would choose to prevent would be smoking tobacco. The history of tobacco is very long; it is believed the people of pre Columbian Americas first used tobacco. It was mainly used for medicinal and ceremonial purposes. (CNN, 2000) Tobacco was first introduced into England in 1565 and for many years was mainly produced for smoking pipes, chewing and snuff. Cigars didn’t become popular until around the 1600’s. Smoking became every increasingly popular throughout the centuries. According to (Ash, 2013) at its height of popularity around 45% of all people in 1947 smoked in the UK.
