Why is she acting like this?

Ok so there's this girl i lke ok she knows it and last saturday she was at a party with a few friends i texted her and asked her what she was doing she said "gettin high" and then she asked me some weird questions like how big is your **** and stuff like that and i told her thats its not funny shes acting like this and its stupid shes high. Ever since then she has not talked to me very much nor has she smiled at me like she used to before this. I really like her but i really think shes stupid for getting high i really dont know what to do especialy since she doesnt even talk to me without ignoring me. Please help me!!!
