If it goes to 6+, it will go to infinity. The only catalyst I see getting it to 6+ will be MRTP designation, it's not going to happen with only MJ and hemp, I don't think.
And that will mean the tobacco industry has been thoroughly disrupted. XXII will be the AAPL or TSLA of the ciggie space.
My strategy, for what it's worth, is that if it gets to 6+, I'll probably put something like a 50% trailing stop on half my shares and hold the rest forever.
Or, until the company gets bought out at for an epic amount of money.
