Question: Under the state's new medical marijuana law, will children be allowed to use the drug? Answer: Children who reside in Illinois and have a qualifying medical condition will be allowed access to the drug. Those younger than 18 will need permission from a parent or legal guardian and must receive approval from their treating physician and a second doctor. Children may be given only marijuana-infused products such as food or liquid drops. For more information about Illinois law, visit www.illinoislawyerfinder.com.
