People, get out your calculator on the tax issue.
Say you are a producer/processor, so only two levels of the 25% excise tax apply.
You sell your cannabis for $5.33/gram to a retail store. The state takes 25% = $1.33/gram. The retail store buys it for $5.33 and keystones the price to retail for $10.66/gram. But since the state wants 25% of this transaction too, he needs to increase the price to $14.21/gram so that after the state takes 25% ($3.55) he will get to keep the $10.66. Now we have total tax of $4.88 on a total sale price of $14.21. Divide 4.88 by 14.21 and you get a rate of 34%. High, but not that bad of a 'sin tax'.
There will also be sales tax on the total, but the state excise tax is 34%, so quit bringing up 85%. That's incorrect.
