The game-changer was focusing on three things: size, airflow, and heat resistance.

Size matters. A device that fits in your palm or a small case is your best bet. It's easy to hide, doesn't crowd your desk, and feels less like a statement. Look for something slim—think a credit card width or less.

Airflow control is your friend. You want to be able to dial in a tighter draw. That reduces vapor production, which means less visible clouds and less odor. Some devices have a slider or ring you can adjust. Test it before you buy if you can.

Heat resistance isn't just for summer. Even if your office is climate-controlled, electronics can get warm. Choose a device with a metal or heat-dissipating body, and avoid leaving it in direct sunlight. A good case also helps.

But it's not just about the hardware. How you use it matters too. Take shorter puffs, and blow the vapor away from your workspace. Consider a small air purifier if you're really concerned. And always check your company's policy on vaping—even CBD products might be regulated.
