Yep, you read that right (You must hold your pinky to the corner of your mouth like Dr. Evil when you say) 1 Million Dollars worth of Cannabis sales a day. That amount has been figured after the first 6 months of Recreational Cannabis sales started in Nevada. These numbers are reported by The Nevada Department of Taxation.

Million Dollar Baby
From a article on Patch.com, Cannabis sales since July 1st when Recreational Cannabis was available for sale in Nevada have exceeded over $195,000,000 with tax revenue over $30,000,000. The state has also reported almost $11 Million dollars through wholesale tax and over 19 Million from retail tax.
In December 2017, the 15% tax on wholesale, retail and medical cannabis from cultivator to dispensary netted just over $2 Million dollars. On top of that, over $3.5 Million was brought in through the 10% retail cannabis tax. That makes the month of December 2017 the 2nd highest tax revenue earner so far for Nevada bring in over $5.5 Million.
