Senior politicians including Prime Minister John Key met with ALCP leader Michael Appleby recently at Ratana.
Mr Appleby, a Wellington Barrister, discussed the Law Commission review of the Misuse of Drugs Act (1975) with John Key and Attorney General Chris Finlayson but both admitted they had not even read the report.
New Zealand First Leader Winston Peters also talked with Mr Appleby and reaffirmed his support for a referendum on cannabis laws.
Labour Party leader David Shearer told ALCP president Paul McMullan that he had been persuaded by research at the University of Otago which claims teen cannabis use lowers IQ.
However, Norwegian economist and researcher Dr Ole Rogeberg analysed those findings, and said the link between IQ loss and cannabis could be explained by socio-economic factors rather than an effect of the drug.
