<human>: Condense the text into a few key points

So my girlfriend recently went to college, and is actually closer to me now that has been in the past. It's been wonderful insofar as we actually get to see each other pretty regularly now rather than with months in between.

However, my girlfriend has also started drinking and smoking a lot since she got here. This doesn't make me uncomfortable because I'm against the actions (I do them too) but rather I think she's just doing them too often. She's started drinking on weekdays when she has classes the next day, and will essentially take any opportunity she can to get high or drunk.

I think this has a lot to do with her new friends that she's hanging out with. However, I don't want to be the bad guy and tell her to stop hanging out with them, since she never really had friends in high school. I do, however, think that these friends aren't the right crowd to hang out with. She keeps blowing off other groups of people because she's not "feeling well" to go hang out with this other group and get cross-faded.

I don't want to tell her to stop because she's new to college and I understand that she has to do some dumb things. I just did this stuff a couple years ago when I came to college and I don't want her to repeat my mistakes.
<bot>: My girlfriend is drinking and smoking a lot, almost every day,  and its interfering with her life. I don't know if I should tell her to stop, or just ride out the wave.
