Legal Question in Family Law in Ohio

Re: custody

"Within the framework of the statutes, the overriding principle in custody cases between a parent and non-parent is that natural parents have a fundamental liberty interest in the care, custody, and management of their children." Santosky

Ohio uses a parental suitability standard/test. "A court may not award custody to the nonparent without first determining that a preponderance of the evidence shows that the parent abandoned the child; contractually relinquished custody of the child; that the parent has become totally incapable of supporting or caring for the child; or that an award of custody to the parent would be detrimental to the child. If a court concludes that any one of these circumstances describes the conduct of a parent, the parent may be adjudged unsuitable, and the state may infringe upon the fundamental parental liberty interest of child custody." Hockstok

You husband can introduce your drug abuse. However, I certainly think you have a strong argument that your occassional pot use does not render you 'unsuitable'.

Good luck
