A handful of other regions have imposed curbs on alcohol, but Kadyrov's move in his mainly Muslim region will be one of the most severe.
It limits the sale of drinks containing more than 15 percent alcohol to between 8 a.m. and 10 a.m. and bans sales of strong drinks altogether during the Islamic holy month of Ramadan.
"Extremism, terrorism, drug addiction and alcoholism are equally bad," Kadyrov said in a statement this week.
"I am choosing a healthy life. We must work together to counter the spread of these unhealthy weaknesses in our population," he said.
Chechnya, theater of a war between federal forces and rebels from 1994, lies in the center of the mainly Muslim North Caucasus, which consumes less alcohol than other parts of the country, where vodka consumption is high.
Some political analysts say Kadyrov is quietly ushering in an Islamic society with rules that order women to wear headscarves and long skirts if working in government offices.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
