Abhishek (27) and Abhimanyu (24) were yesterday arrested by Crime Branch sleuths following a tip-off.
Along with the contraband, police also seized a car which was being used by the duo.
"We got a tip-off that a duo involved in the smuggling of psychotropic substances would come near Bhairon Mandir to deliver a consignment of charas to a contact.
"A trap was laid and, at about 7.30 P.M., two persons, who had come in a Hyundai i-10 car, were apprehended. A search yielded about 8kg charas," said Additional Commissioner of Police (Crime), Ravindra Yadav.
"Unhappy with their earnings, both wanted to earn a quick buck and turned to crime. They got in touch with one Hazi Taslim of Meerut, a known drug supplier of western Uttar Pradesh, and joined his gang," Yadav added.
Further inquiries are on in the case, police said.
