A study for Colorado's revenue authority estimates the demand for marijuana this year at 130 tons. Colorado's recreational marijuana shops have been open for business since the beginning of the year. The report also characterized demand as being larger than anticipated. Most of the marijuana is sold to Colorado residents with only 9% being sold out of state visitors.
"The primary difference is caused by much heavier dosage amounts consumed by the state's 'heavy user' population – those who consume marijuana on a daily basis," said the report, prepared for the Colorado Department of Revenue.
While the amount of marijuana sold is primarily to Colorado residents, among the number of people who buy marijuana, "44 percent of retail sales in the Denver metro area, compared with about 90 percent in mountain resorts."
