A little late to the party, but I got mine.  Probably going to be buying more.

The idea has potential, especially if you're willing  to put the work in.  As far as I know, dispensaries only accept cash, or at least the ones that I've visited.  This could potentially be an easy way for them to use something other than cash.

But it begs the question, why haven't they adopted bitcoin, or some other cryptocurrency yet?  Not trying to question the legitimacy of the coin.  I'm genuinely curious why they haven't done this yet.
