Margaret and William Caldwell
When Margaret and William Caldwell were told by their daughter, Emma, that she was hooked on drugs they didn't know where to turn and had no knowledge of drugs.
Misinformation from a close friend about the effects of drugs led Emma Caldwell to heroin addiction.
Throughout her youth, Emma was a bright and happy girl who was devoted to horse-riding, visiting stables in her spare time.
When she was older it was at the stables that Emma was offered drugs by a friend who gave her misguided information that the effects would help her overcome the loss of her sister, Karen, to cancer.
Suddenly confronted by their daughter's news that she was a drug addict, Margaret and William were left in shock and felt unprepared and helpless. They didn't know enough about drugs to feel they could take control of the situation.
Emma's mother, Margaret Caldwell, said: "We raised Emma in a happy and supportive family environment and so it was felt there was never any need to speak to her about the facts of drugs.
When she was offered drugs later in life she wasn't aware of the consequences and she soon became hooked. We were completely shocked when Emma finally told us that she was addicted to heroin because we had no idea of the signs we should be looking for.
Tragically, Emma entered into prostitution to pay for her habit and she was murdered in 2005.
"It's important that parents are aware that, today, youngsters are exposed to drugs. As parents, they are in the best position to speak to their children about the facts first - before they hear the wrong information from other people or friends.
It's important that children know the consequences so they can make an informed choice if and when they are confronted with drugs."
The Caldwell's now look after their 15 year-old grandson, Stewart, and have developed a strong relationship with him that recognises the need to create an awareness and dialogue on drugs issues.
William Caldwell said: "We have created a close and open relationship with our grandson, Stewart, and we all feel totally comfortable discussing issues surrounding drugs if we need to. We can understand that parents may find it a hard topic to bring up, but they need to be aware that it is just as relevant today as the need to discuss alcohol misuse and sex education.
We make sure we take the time to talk to Stewart regularly, to make sure he is happy and discuss any issues, whether drug related or not."
Margaret and William have used the Know the Score resources to help them discuss drugs with Stewart. Margaret said: "We were keen to support this Know the Score campaign to tell parents that drugs can affect anyone regardless of their background or upbringing. Now that an information source like Know the Score is available to parents, all the help and details about drugs can easily be found to help them find out all they need to know to have the confidence to discuss the issue with their children.
