How to discourage teen marijuana use
Start the conversation sooner rather than later.
As with most potentially awkward conversation topics you need to broach at some point with your child-alcohol, tobacco, sex, etc. - it is best to initiate the discussion earlier than you think is necessary.
While the majority of teens never smoke marijuana, those that do try it may begin even before they are officially " teenagers. " many experts on the topic advise that you begin talking about the dangers of drug use by the time your child is ten or eleven years old.
