The law is different in different parts of the world. In some parts of the world, alcohol can only be purchased in specialty stores. In other parts, it can be bought effectively anywhere.

In line with OP’s question, CVS made a big deal about banning the sale of tobacco in all its pharmacies a decade ago, saying it could not sell tobacco products and be a health care provider at the same time. However, in some states, a CVS will have rows of alcohol for sale because it is legal to sell there.
