Purple haze damn, are you in a rough spot.
Here’s what I’d do, I think:
Sit the kid down, tell her that there will, from now on, be random drug tests. She can choose to continue smoking pot, but if she does, the consequences will be (fill in fate worse than death here). I would add one exception to this: if she’s been smoking and she’s out and needs a ride home, tell her she can call you and you will come get her and you will not lay the smack down on her. Sign a contract, seriously. As long as she calls you instead of getting in a car, no punishment, not even a lecture the next day.
I’m more uptight over drinking than I am pot any day, but no 15 year old should be “allowed” to do either, IMHO. Are there pot users who are responsible? Yes. But you’re the Mom, and until she’s an adult you are responsible for her and what she does. If she gets behind the wheel of a car, stoned, and kills someone, it’s your ass – doubly so if it could be proven that you KNEW she was getting stoned. (Yes, even potheads kill people on the road, too.) Or, God forbid, what if she hurts herself? If you let this slide and something happened to her, could you ever forgive yourself for not setting boundaries?
I’d tell her that until she’s in a place of her own, there are certain things that are expected of her and no weed is part of those expectations. When she’s an adult, she can do what she wants, but until that day comes it’s your job to protect not only her, but everyone else in the household – and everyone AROUND you.
I’d also let her know that privacy is going to be severely restricted for X number of months, until she produces X number of clean pee tests. America ends at the door, she lives in Purple Haze Land. The first thing that needs to go is her internet connection – school stuff only. No 15 year old girl (or boy) needs to have unrestricted access to the net! If you suspect she’s smoking in her room, the bedroom door needs to go for a while.
Another thing she should know is if she gets caught by the cops, you’re not going to be there to bail her out. If, God forbid, she ends up in court, don’t try to get her out of it! I can’t tell you how many lawyers, cops, and judges have told me that parents who refuse to deal with their kids the first time they get into trouble will almost certainly end up in the courtroom again. If she’s going to be a “big girl” and smoke pot, she can be a big girl and take it like a woman when she ends up in juvie for a while.
You need to find out where she’s getting the grass and turn the names over to the cops. If she’s smoking with friends, their parents ought to know that their kids are smoking. They may be idiots and do absolutely nothing about it, but that’s their business. All you can do is warn them.
You were right to read her blog and don’t let anyone tell you different. When trouble is suspected, privacy goes out the door. If she had a boyfriend that was beating her, or was turning tricks, would you “respect her privacy” and butt out? Hell no. Whether you believe smoking pot is (physically) dangerous or not, I know you definitely know that it is dangerous as far as her future is concerned.
She doesn’t need a buddy, she needs a Mom with balls of steel. You’re the woman for the job. She may very well end up a pothead, or just an occasional user, or she may get bored with it and quit – but that’s for her to decide when she’s an adult and responsible for her own actions, living in her own place.
It’s possible to keep the lines of communication open AND put your foot down. Kids today are (silently) screaming for boundaries. You can either set those boundaries and refuse to tolerate foolishness, or you can show her that you really don’t care about her all that much and do nothing. No matter how much you love her, if you just turn a blind eye or just dismiss it with the “most kids are doing it” routine, she will know that Mom can’t handle her own household and doesn’t have the balls to stand up to her.
She may get accolades from all of her friends for having “the cool Mom,” but she won’t respect you.
