Marijuana's changing legal status is complicating matters in family law courts.
The drug remains illegal federally, but its growing acceptance is making it more complicated to resolve custody and child-endangerment disputes that involve marijuana.
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 law enforcement and marijuana activists agree that the drug is increasingly popping up in family law. A pot plant in the basement may not bring criminal charges in many states. But the same plant can become a piece of evidence in child custody or abuse cases.
Colorado lawmakers earlier this year considered updating child-endangerment statutes. But the efforts were abandoned as too complicated.
