One of the "positive" benefits of MJ according to its proponents is that, unlike alcohol, it tends to relax users and make them less aggressive.

Then they will have to explain why it doesn't make black people less aggressive. Blacks are the most violent-prone segment of the population, and MJ use is very high with black males. If MJ has a calming effect, why didn't it calm the black males killed in the recent high profile incidents?

For instance, it was determined after the autopsy that Michael Brown had a large pct. of MJ in his system. Yet he strongarmed a store clerk before getting himself shot and killed while assaulting a police officer. Why wasn't Michael Brown a meek teddy bear from his MJ use?

Which part of "tends" did you not understand?

Why wasn't Michael Brown a meek teddy bear from his MJ use?

Because "pot makes you a calmer, better person" is a fairytale that drug pushers like to tell people. Some people even believe it.
