CALIFORNIA, Pa. -- A local university sent out a health alert to students.



They believe especially harmful marijuana is being spread around the California University of Pennsylvania campus.



The marijuana in question is laced with Jimson Weed and the side effects can be deadly.



The Jimson Weed, also known as "Thorn Apple" or "Stink Weed," dangers come as a surprise to Cal U. students who spoke with Channel 11.



Fortunately, none of the sickened students suffered any critical injuries, but campus officials said there is a reason to be concerned.



School officials are strongly discouraging the use of the substance.



If you or someone you know overdoses, call the health center or 911 right away.
