Humza Yousaf has slammed reports the UK Government could reclassify cannabis as Class A - putting it on a par with heroin and cocaine.
The health secretary told the SNP conference in Aberdeen the Scottish Government was trying to fight the drugs-deaths crisis with "one hand tied behind our back" as key laws remain reserved.
Tory home secretary Suella Braverman yesterday signalled she was "receptive" to toughening laws against the use of cannabis. It would put the UK at odds with most western countries where the drug has been widely decriminalised for personal use.
