By the time they reach the age of 18, about half of all teenagers in the United States have abused a drug at some point in their lives. This is why it's so important for parents to talk candidly with their children about the realities and dangers of drug use at a young age. In fact, studies have shown that parents can reduce the risk of their teenagers using drugs up to 42% by simply talking with them about drug use regularly. However, what's a parent to do if he or she suspects a teen already has a drug problem? This can be a tricky situation, but by handling it appropriately, parents can ensure the best possible outcome.
