Well said.
I think this is backed up by common sense observation as well. Drugs tend to become a plague among those whose lives have been perceived to have become meaningless.
People who have ample reason to believe their lives have meaning, won’t want to spoil them with the abuse of drugs or any other excess. If they use drugs they will keep their use to sane medicinal proportions.
And God looms very large in such a picture. If God seems small, who put Him at the wrong end of the telescope?
