My understanding is that a combination of smoking and heavy drinking is a known factor in OC. Of course, there are people that have done both for years and never get it and as we see here folks that have done neither and get it. But it is a known risk factor.

The other thing with drinking to take into consideration(and now I might get blasted) is what you are mixing it with. Many medications are not meant to be taken with alcohol (and that includes psychotropic medications, sleep meds and pain meds). It doesn't necessarily mean you can't drink ,it just means it's worth looking into.

I think it is a very reasonable question and worth a conversation with your MD if you have concerns about it.
