CHICAGO — Retailers legally selling marijuana for the past month in Michigan say they have drawn customers from surrounding Midwestern states where the drug remains illegal and, as Illinois joined the recreational market on Wednesday, officials were renewing warnings to consumers against carrying such products over state lines.
The dynamic is familiar for states on the West and East coasts where the sale and use of marijuana has been broadly allowed since Colorado’s market opened in 2014, despite a federal ban that created a patchwork of legal and cultural snares. Nebraska and Oklahoma went so far as to file an unsuccessful lawsuit against Colorado, arguing that its marijuana law would have ill effects for surrounding states.

In the years since, the industry has wrestled with questions over companies’ obligation to pay federal income taxes or follow laws on employee safety. Other thorny issues confronted state regulators, who were forced to determine suitable pesticides for growing cannabis plants and which ingredients were safe to include in products meant to be eaten or burned. That terrain is usually reserved for federal agencies.
The tensest point, though, remains the illegal market that has survived in states with legal cannabis markets. Some of that product comes from outside the legal systems tracked closely by states’ regulators, while other states have struggled to keep “diverted” legal marijuana from bleeding into the illegal market at home or in far-flung states.
Data also show that some customers will cross state lines in search of state-licensed marijuana retailers, despite warnings that it’s illegal to take the product back home.
