Adderall addiction

After several years of sleuthing I'm 99.9% sure our 23 y/o daughter is addicted to Adderall & alcohol.

Some of you may have read my posts in the past, most recently the one where she passed out, fell flat on the floor several times, then got up about 2 hours later full of energy, ready to watch a movie like nothing happened. We expected her to have a major hangover in the morning and be sore from all the times she fell flat on her face, however, she bounced out of bed like nothing happened. We asked her later if she remembered anything from that night and she said no.

Fast forward 2 months: She was home over the holidays & was exhibiting what has become her usual behavior over the last several years: bubbly, energetic, talkative, watching TV till 4am, sleeping till 4pm, drinking a 12 pack every night with her boyfriend, etc. This is from a person that is very introverted, especially in groups.

Back to my sleuthing. When she first got home our dog was sniffing in their suitcase and a bottle of pills fell out. I remembered at some point she mentioned her boyfriend takes meds for ADHD. One night at dinner she was talking about how she's started grinding her teeth.

She's dropped out of college and is still living in an apartment with her boyfriend. We are paying her rent & our name is on the lease which doesn't end till the end of July (they have separate leases for the apartment). We can sublet the apartment but are responsible for finding a renter but I literally don't know how to get her out of the apartment.

We haven't said anything to her yet and she will deny it if we do.

I'm very afraid of what she's going to do when we talk with her.
