No More "Drugs" Signage

Why don't they have "Drugs" signs anymore?

Here's a thought. When you're out and about in our Walgreens/CVS society you might have noticed that the word "drugs" has disappeared from signage.

Keeping this fact in mind, why do you speculate that this is so when decades ago, they were commonplace? Seems as if "pharmacy" is the PC word today. Goodbye drugs; hello pharmacy.
