City Hall officials have refused to say how they will monitor who is legally using cannabis in council-owned homes after confirming tenants can take the Class B drug for medical use.
However, police say they will remain vigilant, attending reports of cannabis use to check whether the drug is being used lawfully.
It comes after city man Danny Wilson, who uses cannabis for medical reasons, said he struggled to find a place to live after being evicted from his home due to the property being put up for sale.
Mr Wilson said he was told by the council that he had to declare his use of the drug, which has put off prospective landlords.
Mr Wilson raised the issue at a council meeting asking if the authority recognised the “right of people who use medical cannabis to use their prescriptions in rented property”.
Beth Jones, cabinet member for housing, responded: “The council recognises the right of its tenants to take prescribed medication, whatever its form, within their own council homes.
“There is no change of policy necessary in this regard.
“However, I should point out that social housing providers and private sector landlords may have their own policies and processes over which the council has no jurisdiction.”
Although it is illegal to smoke the drug, even for medical use, it can be vaped if prescribed by doctors.
A police spokeswoman said: “When officers attend reports of suspected cannabis use, they follow established checks to confirm whether the product is a lawful prescription.
“Our role remains unchanged and focused on distinguishing legal medical use from illegal activity.”
