The "invasive ads", while really shitty, are for prescription-only drugs, and it's the drug companies behind those, not the pharmacies. You can't just walk into a pharmacy to get those drugs. They're "convenience stores" in the sense that they also sell things like soap, laundry detergent, toothbrushes/toothpaste/floss/mouthwash, paper towels, toilet paper, cleaning supplies, etc. It has nothing to do with getting people to buy more drugs, it's just another thing to sell. Stores in the US tend to be bigger and stand alone, so if you've got a sizable building you want to fill it with something to sell.
