Peer pressure, particularly among young adults and school children, can result in some bad decisions, such as usage of drugs. Drug abuse, also known as substance abuse, is the utilization of certain chemicals for pleasuring the brain, which end up causing more harm than benefits, in the long run. There are about 190 million people across the world who use drugs, and the number is increasing at a substantial pace, primarily among people under the age of 30. Among the different types of drugs, hashish, cannabis, and marijuana are the most extensively abused ones across the globe. Approximately 141 million people consume cannabis, and about 30 million people take ecstasy and amphetamines.
