Colorado recreational and medical marijuana sales rise slowly? UPDATE

Sales of both recreational and medical marijuana inched up from April to May in Colorado, I THOUGHT.

Those figures come simply from dividing the sales tax rate (2.9 percent) into officially reported (on highlighted links below) sales taxes received:

If those links disappear, this link (or url http://www.colorado.gov/cs/Satellite/Revenue-Main/XRM/1251633259746) should work.  Sales of recreational marijuana were 40.914 percent of the total (recreational and medical) sales in May versus 41.020 percent in April.

Medical marijuana makes up the balance: 59.086 percent in May, up from 58.980 percent in April.

UPDATE:  There’s a discrepancy:

Looking at http://www.colorado.gov/cs/Satellite?blobcol=urldata&blobheader=application%2Fpdf&blobkey=id&blobtable=MungoBlobs&blobwhere=1252008576389&ssbinary=true and trying to get the dollar amount of retail marijuana sold in May, I can come up with

a) $20,705,770, that is, $2,070,577 in 10 percent tax revenue collected divided by 10 percent

or

b) $22,142,207 that is, $642,124 in sales tax revenue collected  divided by 2.9 percent.

I’ve relied on the 2.9 percent sales tax collections before.  Maybe the sales tax number (2.9 percent) reflects sales of pipes, T-shirts, and what not.
