Our Approach

We design vapor hardware from the cannabis inside — not by adapting e-cigarettes.

Most devices start from e-cigarettes

Many cannabis devices are built by adapting existing e-cig designs. They work — but they are not optimized for cannabis materials.

Adapted Design

Cannabis behaves differently

  • Inconsistent power leads to uneven vapor
  • Improper heating damages flavor and actives
  • Thick oils don’t flow like e-liquids
  • Standard coils degrade faster
Uneven Heating

Cannabis-First by CannBro

We engineer the device around the material.

  • Stable and controlled power output
  • Tuned heating curves for cannabis oils
  • Oil flow adapted to higher viscosity
  • Ceramic & materials designed for reliability
