A report by eight state agencies says it will cost between $3.7 million and $7 million to regulate marijuana if Alaskans vote to legalize it.
A legalization measure will be on the primary ballot Aug. 19.
The report collected information from departments such as Public Safety and Environmental Conservation.
The Anchorage Daily News reports the document's authors acknowledge that details of how legalization would be put into practice have not been worked out.
A spokesman for the Campaign to Regulate Marijuana like Alcohol in Alaska says the report was neither objective nor well-researched.
Taylor Bickford says it was put together hastily by bureaucrats who have an interest in arguing for bigger budgets.
The report also doesn't take into account tax revenues generated by legal marijuana.
