My 15 yr old has been vaping on and off for 3 yrs. She gets it from friends and has now told me that her friends are getting annoyed with her. and she can't cope with it. She's high masking neuro diverse and only recently diagnosed after we finally got support in place 2 yrs after an overdose , risk taking behaviour, and self harm as well as a year school refusing. Her meltdowns are distressing for her to say the least and often result in self harm.She feels that vaping helps. She wants us to buy her a vape and fluid,I've refused, but after talking to her in depth, I'm thinking I'd rather know she's getting proper vape fluid than whatever she can scrounge from others and the predators that kids get dodgy crap from in the town. I've talked her through the addiction side that she's already half way down the road to. I've gone through the health risks but she still insists.I keep saying to her she's only 15,it's illegal,it's dangerous to her neuro development.I want to keep her safe but wonder if there are things I just have to accept and pick my battles. We've got her into a small education unit again and hopefully mainstream school part time, huge step forward for her.We have refused to allow her to drink but she's gone to friends houses and had alcohol with adult supervision but been honest about it with us. I'm torn about this because I'm glad she's talking to me about the things she's dealing with like alcohol,vaping and drugs, and if vaping is as bad as it gets I should thank my lucky stars. Drugs are rampant where we are but used to be rare (one of the reasons we moved here), so it's been hard for her to stay out of the way of it but has managed so far. AIBU to relent and buy the vape and fluid? The past 3 yrs has almost broken me and I feel that this is a battle I've already lost so I need to do my best to make it safer for her.
