Hand out discipline.....no questions asked.
Have a 1 on 1 talk and try to reason with them about the affects of smoking pot at their age
Ask a respected teacher or coach to talk to them
Confide in a police officer and ask they talk or scare your kid about the affects of doing drugs
Blame it on their friends and ban them from spending time with them
Do nothing at all and hope the problem goes away
What's the problem with this?
Other....explain
