Let's not ignore this. Disposables are a single-use plastic nightmare. They contain lithium-ion batteries that end up in landfills, and the e-liquid residue can leak into the soil. It's a growing concern, and some places are starting to regulate them.

Pod kits are more eco-friendly, especially if you use refillable pods. You're still replacing coils and pods, but you're not throwing away a whole battery every time. If sustainability matters to you, that's a big point in favor of pod kits.
