Well, one topic which is covered in some detail when you are screened for security clearances is precisely how you use alcohol (and other intoxicants!).

I imagine it is for this precise reason.

Whole lot of Mormons working for CIA and NSA. Just sayin.

Yeah but those same Mormons drink all the booze if there’s no other Mormons at the party.

That might be true in some cases, but I haven't seen it.

The Mormons I've seen tend to be more healthy clean living, than anything else.

It’s perhaps wrong of me to generalize but I’ve lived in Utah my whole life, some are clean and healthy others are unhealthy slobs, just like the general population. The whole ‘drank all the booze’ people are more often those pretending to believe in their faith because of the social repercussions of leaving it.

FWIW, Mormons make great babysitters.

If you read about GRU (e.g. Aquarium) you will see how agents were tested while drunk to see how they behave.
