During the Prohibition era lasting from 1920 to 1933 in the United States, all alcohol sales were banned in the country. However, the federal government made an exemption for whisky that was prescribed by a doctor and sold through licensed pharmacies. During this time, the Walgreens pharmacy chain grew from 20 retail stores to almost 400.[10]
