The state Board of Health voted unanimously Wednesday to lower the fee from $90 a year to $35 a year beginning Jan. 1. Already the $90 fee is lower than when Colorado first authorized medical marijuana a decade ago, when the fee was $140.

The annual fee was lowered because it's sufficient to cover administrative costs.
