There is a difference in HEMP and MMJ. Hemp is a low grade form of pot and highly regulated. Hemp would have been a better choice for HALB and GEAR to tout but they didn't and claimed MMJ which is a horse of a different color. The Michigan bill for hemp is still in the works.
We know that you can do self cultivation in Michigan of up to 12 plants and no farming operations. Canada is possible but if you read the restrictions and what it takes to become a producer it really isn't worth it.
