Further research on my text.

I have decided to use an issue of drugs within the text, therefore I had to understand what drugs can do to a person, I have found a website where people have wrote their stories about how they have been affected by the use of drugs.

Also the link below is website that tells you the possible reasons people may get into drugs, what sort of drugs are illegal and legal, and different contact numbers to help people with the addiction.

Also there is a campaign called 'Talk to Frank' which helps many people with their drug addiction, this has helped many people come out of their addiction and get back to normal life.
