As Homer said;

Alcohol, the cause of and solution to all of life's little problems.

Personally, I'm against religion. That causes more death and misery than all habits put together. And alcohol by itself is not evil nor is it bad for you. In fact, many studies conclude it has health benefits consumed in modest amounts. Smoking, well that is bad for you (although I've been smoking for forty years now) and I do advise younger people not to take up the habit since it is incredibly hard to get away from.
