Input: I've (25f) been debating giving my mom (50s,f) an ultimatum. Im tired of her chainsmoking when Im around and not having respect for my health. She also drinks 2-3 beers/alcoholic drinks on her normal days. This wouldnt be a problem if she didnt underestimate her limit (she weighs a lot less now but thinks she can handle it the same).   She becomes so overbearing when she drinks and I always just want to leave. I do not drink or smoke, so this is important to me.
I was pushed over the edge because of a trip I took with them over the weekend to visit my brothers family. Its a 10ish hour drive to and from and the whole time her and her bf smoked 1-2 cigarettes each an hour. Its their car, they're driving, I toughed it out on the way there.
Now on our way back, Im sick (Sore throat, runny nose, etc.) They lit up the entire time. I told them when there was about 4 hrs left, no more smoking. I was getting seriously nauseous at that point. 
Im just so tired of her addictions and how she acts when I confront her about it. I just dont to be around it anymore. Would I be an Asshole if I cut her off because of these things?
