A lot of people would probably be willing to give up a minor drug or alcohol habit to have/keep a high-paying intelligence job. I would certainly accept being "always sober" as a condition of employment if the job was one I really wanted. I can't find the study, but I seem to remember that alcohol consumption follows the 80/20 rule. A small amount of alcohol consumers consume basically all the alcohol, with non-alcholics consuming very little. If you consume very little, it's probably not a big deal just to go without completely.
