Following a divorce, the family dynamic often changes dramatically. A divorce order may indicate child custody provisions. Parents may share custody of their children or one parent may get sole legal custody, with the other parent having visitation rights. A judge looks and many different factors when deciding how to divide custody but one of the factors that doesn't necessarily disqualify a parent as "fit" is medical marijuana use.
According to the Michigan Attorney General, parents who use medical marijuana will not be disqualified from visiting their children or even getting custody of their children. But this isn't an absolute rule. Like most family court decision, judges have the ability to look at the circumstances on a case-by-case basis.
