This is likely an erroneous argument with little evidence to support it. Violence between street dealers and drug consumptors is unlikely to be the largest source of drug related violence. After all, if the street dealers started killing their custies than no one would buy from them. It's bad for business.
Instead, most heinous drug violence happens between cartels and gangs at the levels of production and [major] distribution [pipelines]. These darknet markets are usually filled with well off youth buying drugs for themselves and their buddies who alternatively would have been unable to source the drugs or would have texted their neighborhood dealer to meetup in a McDonalds parking lot.
