At least 700 cannabis workers in an Albanian village, mostly teenagers and women, have sought medical help after serious intoxication, according to local doctors.

The workers, all of whom tended cannabis fields near the southern village of Lazaret, experienced symptoms akin to “serious disorders from cannabis intoxication,” Dr. Hysni Luka of a hospital in nearby Gjirokaster told reporters.

The symptoms were obviously related to the workers’ jobs of harvesting, planting, pressing, and packing the cannabis, the doctor said.

“The patients, among them also teenagers and even children younger than 15 years, have suffered from bouts of vomiting, stomach pain, heart problems and high blood pressure,” Luka told Albania’s Top Channel TV.
