Nah, I've already talked about Singapore, very stringent drug enforcement and very low rates of violence. The author of the study there was just stating an opinion in that quote.
Your ability to refute a scientific study with "NUH-UH, THE SCIENTISTS ARE DUMMYS!" is as I said before, pretty much the same as global warming denialism. You can argue any point that way, but there is no reason to take you seriously when you do.
Experts agree that the link is valid.
"Recent research has indicated that for some people there is a correlation between frequent marijuana use and aggressive or violent behavior. This should be a concern to parents, community leaders, and to all Americans." -The National Crime Prevention Council

Research found that among youth, the incidence of physically attacking people, destroying property and stealing increased in proportion to the number of days marijuana was smoked in the past year.
According to the National Household Survey on Drug Abuse (now the National Survey on Health) adolescents 12-17 who use marijuana weekly are nine times more likely than non-users to experiment with other illegal drugs or alcohol, five times more likely to steal and nearly four times more likely to engage in violence.9

precipitate psychosis or
panic attacks which could have easily led to Martin misinterpreting Zimmerman's benign intentions.
It's a disgrace that we allow children to have access to addictive poisons like this.
Each year, more teens enter treatment with a primary diagnosis of marijuana dependence than for all other illicit drugs combined. Over sixty percent of teens admitted to drug treatment cite marijuana as their primary substance of abuse.
Even marijuana proponents acknowledge that marijuana use is harmful for teens. Allen St. Pierre, the executive director of NORML (National Organization for the Reform of Marjuana Laws) recently stated that "One can argue before a young person reaches full brain development in their early 20's, they should not use or have legal access to marijuana."1
