Cannabis is now legal for medicinal or recreational use (or both) in 33 states and the District of Columbia. As of Oct. 17, 2018, it also became legal throughout Canada.

More states are expected to legalize cannabis in some form this year. That means litigation concerning cannabis can be expected to grow, well, like a weed.

There are obvious product liability claims related to the sale of cannabis products—for example, products that are tainted or mislabeled.

Criminal cases are expected to define and refine issues surrounding impairment and the levels at which use of cannabis-related products can be prosecuted.

No doubt, there are cases that will involve trademark issues. But what about cases in which cannabis growers bring claims against others for damaging or killing their crops?
