SALT LAKE CITY -

Parents of Utah children with severe epilepsy are cheering a new state law that allows them to obtain a marijuana extract they say helps with seizures, but it's unclear how and when they'll procure it.

Utah's Republican Gov. Gary Herbert has already approved the law and is holding a signing ceremony Tuesday afternoon.
    
The new law doesn't allow medical marijuana production in Utah but allows families meeting certain restrictions to obtain the extract from other states.
    
The extract, which some believe helps with a severe form of epilepsy, is produced in nearby Colorado and is designed not to produce a high.
    
But Colorado experts say restrictions passed in that state to appease the federal government make it a murky process for Utah families to actually get marijuana-derived products.
