Parents caught using or possessing marijuana will be at much less risk of losing custody of their kids under a new rule change being pushed by the City Council.

The council’s General Welfare Committee on Monday passed a resolution calling on the city’s Administration for Children’s Services to clarify its official policies to ensure that parents possessing or smoking pot in and of itself doesn’t create an “imminent risk of harm” to a child — something that could warrant an official ACS investigation that could lead to a child’s removal.

Of the 34,642 allegations of child endangerment fielded by ACS between July and September of last year, 15% were for substance abuse, including opioids and marijuana. The data include both parental and child drug use.

The nonbinding resolution, introduced by Councilman Brad Lander (D-Brooklyn), is expected to be ratified by the full council at Tuesday’s meeting.

“It is time for ACS to adopt a simple policy,” Lander said.

Council members are lobbying for the rule even though ACS Commissioner David Hansel testified in April that his agency is already doing what Lander is calling for.
