Probably a good idea, all things considered. Secondhand smoke is the least of the business owner's liability. There are issues with over serving as well - how does a budtender accurately gauge when someone is "too stoned" and needs to be cut off? Will people be driving after indulging or walking in the subzero weather and what kind of liability will that incur for the business? Should there be a lower maximum purchase for on site vs home consumption? Just too many unknowns and with Trump and Sessions the whole future of legal weed is hanging by a thread anyway. Much as some may wish we could have Amsterdam style coffee houses I think as Americans we are too litigious and quick to lay blame to be able to handle it.
