Addaction has launched a website offering advice to young people aged 10-16 about drug misuse.
The site, which is sponsored by HSBC, is accompanied by a cartoon booklet with information on how to handle real-life scenarios.
Young people who use drugs start doing so at an average age of 14, but rarely approach services for help before their mid-20s, according to Addaction research.
The information drive is being spearheaded by Youngaddaction, which deals specifically with children and teenagers.
Tony Addison, a former drug user now in his 20s, said: "When I was a teenager it was hard to get information you could trust about drugs. When adults around you just say drugs are bad but kids at school are saying they're fun, who are you going to believe?"
Peter Martin, chief executive of Addaction, added: "Young people who are concerned about drugs often find it hard to ask for help. They are more likely to use services that speak their language."
