Why would somebody buy a gallon of acetone?  Are they making drugs?

Acetone can be purchased by an individual for various purposes, including cleaning and refining gemstones, refueling fuel cells, making homemade polishes and stains, and removing nail polish. It can also be used as an ingredient for drug production, so some individuals may purchase gallons of acetone for illicit activities.
