Drugs are everywhere and easily getting into the hands of school kids

I am a teacher by profession. Recently I am seeing the increase in drug usage among school students in coimbatore

It's becoming very hard to curb too. Although we educate alot about these in schools it's becoming very common among youngsters.

I think parents have a very big role to play to curb this. Sofar I have observed the following reasons are common among students who are into drugs.

  1. Giving more money to kids than they need.

  2. Not following their activities because they are busy with their life.

  3. Not knowing thier friends well.

What do you guys think? If you have anything else please share it might help me to understand this problem better.
