Going to a party and I really really hate taking drugs, will people be angry if I ask if everyone is sober?

I don't like drugs.<br><br>In fact I hate drugs. I'm not going to go into a whole I'm sober and you should be too thing. It's just not my cup of tea.<br><br>I'm meant to go to a party and I'm worried that if I ask everyone if they're sober before I go that it'll be seen as an attack on their lifestyle, or just make people angry for some reason.<br><br>If I go into the party and everyone is off their faces on drugs I feel like that'll be super uncomfortable for me.<br><br>What do I do here?<br><br>Is it okay to enquire about people's drug habits?<br><br>Or will that just offend?
