Society itself sometimes compels us to walk down roads that we would have never gone down. When you socialize more and are an active member of society then people will influence you. You may not want to be influenced but sometimes these influences are what compel people to use drugs. It's further proof of how addictive our society is and how difficult it can be to seek help. 

A giant factor to consider is the media influence. Songs and movies about drugs seem compelling to younger audiences and those who do not know better tend to use drugs for the sake of it. You might want to try a new drug just to seem cool in front on your friends but the repercussions that you might face afterwards would be drastic. 

Education among masses is important to prevent drug abuse. Young people are more susceptible to using drugs without knowing all the consequences. It's because most people still see drugs as a social menace and people who use drugs are seen as morally weak characters. The truth is that drugs change the way your brain works and leave you helpless. It takes just that one gateway drug to become an addict. 

How can you stay away from Societal Influence? 
If you like you are being compelled to use drugs by somebody then it's absolutely okay to cut ties with such people. Drugs may seem like a good idea in the short run but sooner than later they lead to serious health problems. 

Educating yourself about drugs and the way they work is also important. This will help you realize why even that one gateway drug might cause you a lot of problems in the future.
