The performance of the anti-quackery drug inspectors has raised questions regarding the performance of the district administration, the Young Doctors Association (YDA) members said on Thursday. The drug inspectors have managed to seal only 300 clinics of quacks in Lahore, while the YDA survey report claimed that there were 300 clinics of quacks in Shahdara alone and thousands of them in Lahore, where thousands of patients fall prey to these quacks daily.
