Why do people get addicted to drugs

Well I think and strongly believe that people get addicted to drugs because maybe the crowd of people that person surrounds there self by. It is also peer pressure from there friends and people and from friends from school. It's very easy to find someone that would do that and have that and call themselves your friend in that moment. It'll be wise and smart to just say no. It'll get you far in life and make you someone important as well.
