What do you think of me talking about drugs in front of my friend?
Oh my, will your friend be okay with you discussing drugs?
I'm sure that they will get over it.
I understand they will get over it, but it may still make them uncomfortable.  You should be careful  discussing different topics with your friends, it's important to be considerate with certain matters.
I don't think so. I'll decide what my friends should be okay with.
It is not up to you though. If you are not considerate of them, they might not want to hang around you.
