You can give black and white facts but don't get too technical. Tell child about things like beer, wine etc not amphetamines for instance. Keep your facts basic. Tell them good and bad habits such as going out for dinner versus drinking by binging. Tell them what people look like and act like when they get too much. Avoid words like drunk or intoxicated. Tell them the repercussions such as losing your job and not taking care of your responsibilities. Tell them their is help is available and somebody should ask for it if they need it.
