Girlfriend and her parents smoking in the car with me in it?

I'm 20 and my girlfriend 19 is a big pot head while I never smoked a joint my life. I never really cared for it since all I cared about was her. She invited me to play golf at the time and said her parents offered to pick me up. The time comes and they pick me up and keep in mind they are nice people and suddenly on the way there they all just start smoking their vapes including my girlfriend in the backseat and Im just awkwardly their just sitting taking everything in. We get there and play golf and we end up going to the beach at around 9pm. The beach is pretty empty and again they all roll up a joint this time in front of me in the middle of the beach and make sure to lookout for any cops so they don't get busted. At this point I start getting a bit uncomfortable since I'm not a smoker and I'm just watching my girlfriend and her parents smoking while they chat to me. Is this normal or am I just overthinking this?
