My daughters are very close. My 18yo privately informed me that her sister (15yo) told her she just tried mushrooms and now wants to try acid. She said she has all of this under control and makes good decisions, but she wants to do this. I also learned she has a boyfriend who was caught using some drugs in 8th grade (??). For me, this is all shocking and new. My 18yo (a senior, popular, social, outspoken) drinks with-friends, smokes pot on occasion, the expected. She tried mushrooms last year, had a bad experience and called us. We Uber'd her home immediately, held her and all was good. Next day we chatted. She's the one who hasn't thrown up all night among her friends, takes care of others, etc. My younger was so cheery when she was little and now seems to have a low level of sadness or anxiety, but is also very social, popular, etc. She's more edgy. Similar to my sister and me (Im the older, sister experienced addiction). My younger has a very high IQ; adults often comment on her maturity and mind. As a parent, I decided to scare the of out them regarding family members and addiction. Both girls have done school presentations on this sort of stuff and seem make smart choices always, until now. Big sis doesn't want to reveal that she told us (parents), so for now I'm rescheduling weekend events, tightening the reigns and seeking advice before we make our move. We just don't know what that move is. HELP! ADVICE! TRYING TO GET IN FRONT OF THIS! THANK YOU!
