Meh, I'm betting that the folks that have been buying pot for years have probably never used credit or debit cards to do it.

I'm pretty sure that pots has been a cash only business since it was made illegal. So the only thing now is that folks that might not do it when illegal now have to use cash if they want to do it. I guess it therefore may limit sales to "new" customers. But "old" customers aren't doing anything different than they've ever done.
