<human>: This feels like mostly a rant but i think its helpful to let everything out.. i think.. Anyways, I strive to be clean and sober. If it wasn't for my bf who's still in university I would never drink and as it is I always rebuff his requests for me to get high with him. Personally drugs and alcohol are just as disgusting as vomit and shit in my opinion. He's the opposite of me where he smokes upwards to 7 grams of marijuana in a day and never says to to his friends when they ask him out to go drinking or other illegal drugs. 

On to the incident; Last night we had discussed going out for dinner around 9pm. 9pm comes and goes and around 10pm he asks me to come hang out because he was fishing with his friends. I say no at first but with a little emotional manipulation I go out. It's 11pm by the time I reach the docks and he's past buzzed and high. He asks me to drive us to his place (45 min one way) and I comply. On the way there he drinks whiskey from a water bottle. We also stop to pick up a 1L of another alcoholic drink which I can't remember. In the end I drop him off back at the docks where he finishes off the bottle and smokes 2 more joints and I head back home around 2.30 am. Today he asks if I'm coming over to take care of him. And at this point I'm not sure what to do... I only drink in moderation and I believe if you get hungover and you're puking your guts out, shame on you. But I don't really want to say that to my bf :/ So in the end I made up some excuse and that was that.

Summarize the given text in a few sentences.
<bot>: What do I do or what do I say to a bf who has no self control and who can't make responsible decisions when it comes to alcohol and drugs?
