The 18th Amendment to the U.S. Constitution banned the making, selling, and transporting of alcoholic beverages throughout the United States. Ratified on January 16, 1919, it took effect one year later on January 17, 1920, and it stayed in force until the 21st Amendment repealed it on December 5, 1933.1Congress.gov.

The Ratification of the Twenty-first Amendment It is the only amendment ever fully repealed by a later one, and the era it created is known as Prohibition.
What the Amendment Banned
Section 1 prohibited the manufacture, sale, and transportation of alcoholic drinks anywhere in the United States and its territories. It also banned importing alcohol into the country and exporting it abroad.3Congress.gov. U.S. Constitution – Eighteenth Amendment The critical phrase in the text is “for beverage purposes.” The target was drinks people consumed for their alcohol content, not every product that happened to contain alcohol. Industrial solvents, cleaning products, and certain medicines were handled differently under the enforcement laws that followed.
The amendment went after the supply chain. Breweries, distilleries, saloons, and liquor importers all had to shut down or reinvent themselves. Thousands of businesses that had operated legally for decades were suddenly on the wrong side of the Constitution.
What It Did Not Ban
The 18th Amendment did not make drinking illegal. Neither did the Volstead Act, which enforced it. The Volstead Act did not specifically prohibit drinking or buying alcohol, and it allowed people to keep and consume beverages they had legally acquired before the ban took effect.4Congress.gov. Amdt18.1 Overview of Eighteenth Amendment, Prohibition of Liquor If you stocked your cellar before January 17, 1920, you could legally drink every bottle at home.
That distinction mattered. Wealthy Americans who could buy in bulk ahead of time were largely insulated from Prohibition in their private lives. The constitutional restriction fell on the commercial side: making it, selling it, moving it. A glass of wine at your own dinner table was never the crime.
The Loopholes People Used
Several legal exceptions created gaps that millions of Americans exploited.
Sacramental Wine
The Volstead Act let churches and synagogues keep using wine for religious ceremonies. Clergy could obtain permits, and Jewish households were entitled to a set amount of wine per adult each year for ritual purposes, certified by a rabbi. The number of people claiming religious need for wine surged, and enforcement officials struggled to sort genuine practice from creative thirst.
Medicinal Alcohol
Doctors could prescribe whiskey and other spirits. Federal rules limited prescriptions to one pint per patient every ten days. Pharmacies filled these like any other medication, and physicians willing to write generous prescriptions did brisk business.
Home Cider and Fruit Juice
Section 29 of the Volstead Act exempted the home production of “non-intoxicating cider and fruit juices” for personal use. The law never clearly defined “non-intoxicating,” and plenty of Americans fermented grape juice and cider at home until it was very much intoxicating. California grape growers even sold bricks of compressed grape concentrate with warnings that told buyers exactly what not to do if they wanted to avoid making wine.
How It Was Enforced
The amendment itself was short. Section 2 gave Congress and the states “concurrent power” to enforce the ban through legislation.5Congress.gov. Amdt18.8 Federal and State Enforcement Powers The specifics came from the National Prohibition Act, better known as the Volstead Act, which Congress passed in October 1919 over President Wilson’s veto.
The Volstead Act set the legal threshold for “intoxicating” at just 0.5 percent alcohol by volume.6United States Senate. The Senate Overrides the Presidents Veto of the Volstead Act That strict cutoff swept in beer, wine, hard cider, and spirits alike. Penalties for a first offense started at a fine of up to $1,000 or up to six months in jail. Repeat offenders faced steeper fines and longer sentences.
In practice, enforcement was uneven. Federal Prohibition agents were chronically underfunded, and many state and local departments had little enthusiasm for the job. Corruption was common. Agents and officials sometimes took bribes from the same bootleggers they were supposed to be arresting.
Why It Was Repealed
Public support eroded steadily through the 1920s. Bootlegging operations ranged from small-time moonshiners to sophisticated criminal enterprises run by figures like Al Capone, and organized crime grew enormously by filling the vacuum left by the legal alcohol industry. Americans who had initially backed the ban grew tired of the violence, corruption, and hypocrisy that came with it.
Money mattered too. Alcohol taxes had accounted for roughly 30 to 40 percent of federal internal revenue before Prohibition. The federal income tax, authorized by the 16th Amendment in 1913, had made it financially possible to give up that revenue, but the lost dollars still stung once the Great Depression hit in 1929 and the government needed every source of income it could find.
The 21st Amendment did the work of repeal with a single sentence: “The eighteenth article of amendment to the Constitution of the United States is hereby repealed.”7Congress.gov. Constitution of the United States – Twenty-First Amendment It was ratified on December 5, 1933, using state conventions rather than state legislatures. That method has never been used for any other amendment before or since.8Congress.gov. Amdt21.S3.1 Ratification Deadline, State Ratifying Conventions
What Repeal Actually Restored
Repeal did not simply return the country to its pre-1920 rules. Section 2 of the 21st Amendment handed authority over alcohol regulation to the individual states, making it illegal to transport or import alcohol into any state in violation of that state’s own laws.9Congress.gov. Twenty-First Amendment Section 2 Each state could set its own rules on sales, licensing, taxation, and even complete prohibition within its borders.
That patchwork survives. No state currently bans alcohol entirely, but 33 states let local jurisdictions restrict or prohibit alcohol sales. Dry counties still exist in parts of the South and Midwest. The 18th Amendment is long gone from the Constitution, but its echo shows up every time you cross a county line and cannot buy a bottle of wine at the grocery store.
