Glass pipes, aka "hand pipes," are one of the most classic ways to enjoy a smoke. Since glass hand pipes don't require water, all you need is a lighter and some of your favorite dry herbs to get going if you have your pipe. Hand pipes are mostly small and portable, so they'll fit easily into your pocket, and they're perfect for on-the-go use. Combine their form factor with their ease of use, and you've got one practical smoking device.
