The Question of Condom Use
Findings regarding condom use among people who drink prior to sex are mixed. While high percentages of people who drink fail to use condoms during sex, it might not be due to the booze. For example, it could be that people who are more likely to drink are also less likely to use condoms in general. Walsh says that the only finding here that seems to have consistent support is that people who use condoms when sober usually also use them when they are drunk (and the same goes for people who don't use them).
