Mr Sefa-Kayi who has been an advocate for the legalisation of growth of weed in the country said there is the need for a matured conversation about marijuana.

When asked by Joy FM's Lexis Bill if he smokes weed in an interview, he said he does not but rather smokes cigarette.

"I don't smoke weed but I smoke cigarettes," Kwame Sefa Kayi said.

He explained his advocacy was not a call for the legalization of smoking weed but for it to be used for commercial activities under very secured controlled environment.

According to him, prominent individuals like the late UN Secretary-General Kofi Annan made the same call.
