Science is the study of the admitted laws of existence, which cannot prove a universal negative about whether those laws could ever be suspended by something admittedly above them.

Drink because you are happy, but never because you are miserable. Never drink when you are wretched without it, or you will be like the grey-faced gin-drinker in the slum; but drink when you would be happy without it, and you will be like the laughing peasant of Italy. Never drink because you need it, for this is rational drinking, and the way to death and hell. But drink because you do not need it, for this is irrational drinking, and the ancient health of the world.
