Today on the 21st: We continued our “State of Cannabis” series with a discussion about how to talk to kids about marijuana, now that it’s legal for adults in Illinois. We also spoke with patients who use cannabis for medical purposes about what changes for them in the era of legal recreational weed, learned how some colleges are stepping up to help prepare students to break into the cannabis industry and explored the challenges Illinois farmers are facing when it comes to growing a plant related to marijuana: hemp.
