On Thursday morning, the Socialist Party got to chose the issues for debate.
They called for drugs to be decriminalised.
It was the only way to fight the drugs menace, they argued.
Addicts should have the right to treatment within seven days.
If necessary they should be prescribed heroin as they began their rehabilitation regime.
The motion was defeated by 79 votes to 6, the SNP and the Greens abstained.
The second Socialist debate was on the pensions dispute in local government.
Socialist leader Colin Fox said the Scottish Executive was using European law - scrapping the so-called rule of 85 which allows some workers to retire at 60 - to mount a wider assault on public sector pensions.
