You've seen the headlines: "Global vape market to reach $XX billion by 2030." Those figures are for investors and corporate strategy, not for deciding how many units of a new disposable to order. A national number doesn't tell you if your neighborhood skews toward high-nicotine disposables or refillable pod systems, or if a local flavor ban is about to crush sales.

When you stock based on a national forecast, you risk overbuying products that sit on your shelf. That ties up cash and shelf space, and vape products don't improve with age. The solution is to build a local market estimate using data you can actually verify.
