Video will play in Play now Don't auto playNever auto playA disturbing video has surfaced showing men frothing and slumped seemingly comatose at an Auckland playground after allegedly smoking illicit drugs. Drug Foundation executive director Ross Bell viewed the video and said it could show booze or synthetic cannabis use. He said since the government changed the law in 2014 to regulate synthetic cannabis, no products had been approved and a black market had developed. "The problem with synthetic cannabis is it is impossible to know what it is. "The chemicals making their way into synthetic cannabis are dangerous, unknown and can be different from batch to batch, which can cause effects like those shown in the video," Bell said.
