An invention I dislike

In present-day society, more and move inventions have been invented, some of those inventions are advantage to our life, but some of them is disadvantage, such as the invention which I dislike is narcotic drugs.

The narcotic drugs used to be advantage, but now some people are using them in the bad way. Narcotic drugs was invented to cure or help to cure some people’s disease, such as, operation anaesthesia, manic depression and anhypnia. Nowadays, they are also using to help curing human’s disease, but some bad guys use them to control people and earn money from them. Finally the people are addicted to narcotic drugs, and dissipate their fortune

In conclusion, the narcotic drugs is one of the inventions which I dislike, I know so many negative part about them because they had been advertised by the government of my country.
