Re: 17 year old son's marijuana use
I work with high schoolers, have a 21 year old son, used drugs in the past and heard that balony excuse from them also.
When a teen tells me, well you used drugs before OLD MAN. I always reply with, "But we didn't know then what we know now about drugs and pot in particular, young wipper snapper!" That answer works pretty good. But sad to say it didn't help a single soul I know stop from using drugs if they were determined.
Mom, you will worry about your son until the cows come home, but don't stress it so much. When you find his drugs, paraphenlia, or him high just do what you do! Yell, toss it out, call the police.
If the boy is ready to do the crime let him do the time. You may not be able to change him but you don't have to make things easy for him also.
