can tanczos slushies get you drunk drunk?

i’m 21, and i just don’t drink alcohol. but my mother is a close to extreme alcoholic. her and i have to be on the road tomorrow and she’s sat with a very large styrofoam cup of one of those alcoholic slushies from tanczos right now. i get very anxious when she drunk and she always seems to carry it into the next day. but since im unfamiliar with the alcohol content of these drinks idk if i should be overly worried about it right now (sorry if this is the wrong community to put this under, please tell me if it is)
