A Pennsylvania Hemp Industry Council test plot of hemp grows in July 2017 on Lehigh University land along Center Valley Parkway in Upper Saucon Township. Hemp grown under Pennsylvania's research program for fiber and seed won't get anyone high. It must maintain a concentration of the psychoactive chemical tetrahydrocannabinol (THC) below the 0.3 percent legal threshold. Courtesy photo | For lehighvalleylive.com
