YOU ARE THE INVESTOR. YOU CAN DO THE SAME DD THAT I DID.
Share auth is 20 billion, per amendment they filed in Wyoming in Jan 2018 (hint, look it up on the Wyoming business website, under North american Cannabis.) You could also look at the top sticky post from me, too.
Can't help you with hints for the rest of your verification. You could look at their financial report, which gived the O/S count as of 12/31/2017, but you would have to look at Wyoming for the share auth raise to 20 billion shares.
Feel free to thank me later for helping with this important DD.
