The Supreme Court plans to overhaul the practice of illegal drug trafficking, the work of the juries, and the appeals system for disciplinary rulings of qualified chambers, Lebedev said.
Putin asked him if the special anti-drug body that had been set up helped change the situation.
"There is a good trend of prosecuting not only those who buy drugs for themselves, but also those who buy, sell and push drugs," he said. "[But] these people should not only be isolated but also treated."
Lebedev called trial by a jury a relatively new procedure in the Russian justice system.
"Many mistakes are made, mostly due to the misunderstanding of the Criminal Procedure Code," he said.
"The introduction of the justice of the peace helped us solve a crucial problem, bringing us closer to the people," said Lebedev.
According to him, judges from such lower courts [junior judges] consider 65% of civil cases and 30% of criminal cases, which helped relieve part of the burden on courts with general jurisdiction.
Lebedev said junior judges have considered 3,778,000 civil cases. He also said the quality of their ruling had improved.
