DENVER -

Colorado lawmakers have started work on two hot-button marijuana measures in the final weeks of this year's legislative session.

One bill would lower possession limits for concentrated forms of marijuana such as hash oil. Currently, Colorado adults are allowed to possess up to an ounce of marijuana, no matter if it is leafy flowers or concentrated oils. But in its concentrated form, an ounce of pot has more servings than in its plant form.
    
Another bill would broaden a ban on certain types of edibles to include products that mimic other foods or candies. Some marijuana activists fear the bill could ban any type of edible pot.
    
Lawmakers heard testimony on both bills on Thursday, but a vote won't happen until next week.
