Expect Marijuana Shortages When It Becomes Legal in Illinois

Over-regulation is a key factor.

Medical marijuana is one step closer to reality in Illinois after a panel of lawmakers approved regulations for patients, growers, and retailers.

But even after it becomes legal January 1, there still may not be any to buy, reports CBS 2's Derrick Blakley.

Approval on medical use of pot came, appropriately, from the Joint Committee on Administrative Rules.

"This is the most highly regulated, highly controlled, safe medical marijuana law anywhere in the country," said State Rep. Lou Lang, (D-Skokie).
