My friend during pregnancy

So last week I went to a kick back and my friend decided to smoke a blunt and have alcohol. The next stay she announced on Instagram that she was pregnant. I asked her when did she find out and she said October 1st and the kick back was November 1st. Idk how far along she is and of course I didn’t know she was pregnant until she announced it on Instagram. Now she went to the store and bought wine and she thinks it’s ok. What do I do? I don’t want her to hurt her baby and I don’t live with her but this is harmful.... right?
