Is this because men are much more likely to use + sell drugs, much more likely to be violent, or are targeted more heavily?
Without citing a source, you might as well say black psychology leads blacks to being larger risk takers. Otherwise you're just describing your stereotype.
http://www.telegraph.co.uk/science/evolution/9005552/Men-twi... "They said the gap between men and women when it came to risk-taking was 'unexpected in its magnitude.'"
http://www-personal.umich.edu/~kruger/risk.html: "More frequent risk taking among young men than women has been explained as a sexually selected trait, perhaps advertising male quality."
http://www.epjournal.net/wp-content/uploads/ep062942.pdf: "Men are also more likely than females to cross busy roads when it is risky to do so."
I don't have a citation for the statistics offhand, but from my work in drug policy, I can tell you that men and women (in the aggregate) are convicted of very different drug crimes.
Put another way, if you went to a men's prison and a women's prison and took a random survey just of the inmates who are serving time due to drug-related crimes, you'd end up with very different cross-sections.
This page -- https://en.wikipedia.org/wiki/List_of_countries_by_incarcera... -- lists several countries with comparable rates not fully treated in the page in the original link.

In many other countries with much lower incarceration rates, the rate of people at large with prison history is much higher, which makes societies criminalized even down to the national character (see 'why Russians don't smile' - spoiler - smile is a sign of submission in prison).
Is TIL next?
