RE:Supply and DemandThose who buy from criminals will be slow to transition to legal but more and more will over time.
The market opportunity is not with these folks, it is with those whodo not wish to deal with black market are who are looking to a safe supply of cannabis for both rec and medical purposes.
Once fully legal i would bet that will be a bigger demand for pot than many expect. This has been seen in Colorado and other states where legalization has been in place for awhile now
