Scientists at Harvard Medical School recently built a device designed to allow you to smoke weed inside an MRI scanner. The Device allows researchers to observe activity in the brain, and doing so while smoking tobacco or pot could enhance our understanding of addiction and how to treat it.

Blaise Frederick constructed a makeshift water pipe inside of a picnic cooler, then ran 2.4 meters of tubing to a plastic facemask that rests inside of the scanner. Since the mask is made from materials that are not magnetic, it will not interfere with the imaging.

His colleagues have tested the device on 9 volunteers at McLean Hospital. Frederick and his team will receive a grant to conduct further studies with marijuana..
