A vigorous back-and-forth between pot legalization supporters and foes entered the religious arena Wednesday. 

Opponents planned an announcement of faith leaders calling on Coloradans to reject making pot legal without a doctor's recommendation. 

In response, legalization supporters released a list of clergy members who support legalizing the drug and ending criminal penalties for its use. They say religious leaders and parents should guide decisions about marijuana, not the law. 

Colorado is one of three states debating ballot measures to legalize pot for adults. Already Colorado's measure has divided business leaders and a workers' union.
