What is the difference between MMJ and traditional cupping device?
A. Traditional cupping device burns out the oxygen in the jar to reduce the pressure. MMJ use a screw-like device to adjust the volume inside the jar, and hence adjust the pressure. The advantage of MMJ over the traditional cupping device is that no fire used with MMJ. It is therefore safer. Moreover, the pressure is adjustable for MMJ. One can apply a larger pressure to the affected area to achieve greater effect while others can adjust to weaker suction if they can accept less pressure.
