(AP) — Colorado’s pot regulators are laying out how much it’s going to cost to join the newly legal business.

The Colorado Department of Revenue started three days of public hearings Tuesday to explain all the regulations to people who want to be in Colorado’s marijuana business. It’s legal, but that doesn’t mean it’s going to be cheap.

Application fees run up to $5,000. Operational licenses cost another $2,750 to $14,000. Those who want to sell both medical and recreational pot would have to pay double.

The regulations are final Oct. 15. Some in the marijuana industry want the Department to reduce fees for people selling both medical and recreational pot.

Retail marijuana sales begin in Colorado Jan. 1.
