I do I don't think there is really a formula that we can do or apply so kids won't even try to take drugs. Children/teens start using or trying drugs for many reasons. There's curiosity on how it feels or what it's like. The desire to fit in a group, peer pressure while some start using as a way of coping with problems (anxiety, depression, anger). One thing that we can do is being a good role model for them. Older family members can serve as model for the younger ones with regards to alcohol and drug use. They can influence the children if the children sees that they themselves, the parents are not using drugs or drinking responsibly, if not at all. We can talk to the kids about drugs and alcohol as for me, it is better for them to hear it out from me than from his peers who may not know better.
