"Some quit altogether; most, however, had moderated their drinking — to 14 drinks a week or fewer for men, 11 or fewer for women."
Here's a persistent side effect: The lied a lot about how "few" drinks they had!!
Moderation may work for some, but for a true alcoholic or addict, the prescription should be NONE whatsoever.
But the recovery business is income generating. Many would gladly have their family or insurance pay for some bogus "moderation" treatment, because they want to KEEP ON DRINKING, until they change their mind for good.
Don't forget the tax revenues. If smoking and drinking were banned the govt would lose billions.
