A Colorado man loses custody of his children after getting a medical marijuana card. The daughter of a Michigan couple growing legal medicinal pot is taken by child-protection authorities after an ex-husband says their plants endangered kids.
And police officers in New Jersey visit a home after a 9-year-old mentions his mother's hemp advocacy at school.
While the cases were eventually decided in favor of the parents, the incidents underscore a growing dilemma: While a pot plant in the basement may not bring criminal charges in many states, the same plant can become a piece of evidence in child custody or abuse cases.

"The legal standard is always the best interest of the children, and you can imagine how subjective that can get," said Jess Cochrane, who helped found Boston-based Family Law & Cannabis Alliance after finding child-abuse laws have been slow to catch up with pot policy.
No data exist to show how often pot use comes up in custody disputes, or how often child-welfare workers intervene in homes where marijuana is used.
But in dozens of interviews with lawyers and officials who work in this area, along with activists who counsel parents on marijuana and child endangerment, the consensus is clear: Pot's growing acceptance is complicating the task of determining when kids are in danger.
A failed proposal in the Colorado Legislature this year showed the dilemma.
Colorado considers adult marijuana use legal, but pot is still treated like heroin and other Schedule I substances as they are under federal law. As a result, when it comes to defining a drug-endangered child, pot can't legally be in a home where children reside.
Two Democratic lawmakers tried to update the law by saying that marijuana must also be shown to be a harm or risk to children to constitute abuse.
But the effort led to angry opposition from both sides — pot-using parents who feared the law could still be used to take their children, and marijuana-legalization opponents who argued that pot remains illegal under federal law and that its very presence in a home threatens kids.
