Residents who live near the park said the strong smell was 'impacting on the quality of their lives' on a regular basis.
West Yorkshire Police has increased patrols in the area since receiving the complaints.
On Saturday evening, a male was caught smoking cannabis close to the park, but claimed he thought the possession of cannabis was legal.
In a Facebook post, Leeds East police warned the public that action will be taken against anyone caught with the drug.
PC Johnson, the officer in charge of the patrols, said: "I understand that individuals have differing opinions whether or not it should be legalised but at this time possession of cannabis remains a Class B drug.
"It is not possible to legally possess this drug even for recreational use. Legal action will be taken against those found with it in their possession."
