Cannabis advocate Andre Du Plessis lit up and smoked a fat joint during a live TV interview on the South African Broadcasting Centre.

The head of the Cannabis Working Group was taking part in a panel discussion on SABC television about the legalization of cannabis with Central Drug Authority deputy David Bayever, when he sparked up the joint.

The interview then came to an abrupt end after he walked off the set.

The South African Broadcasting Centre uploaded the clip to YouTube with the following description: ‘The newsroom does not condone the actions of our guest Andre Du Plessis. The views expressed in this video clip/interview are not that of the SABC and Associates, but that of the guest.
