Barry is correct. As an 18 year old in the early 90's, I got my drink on!!!!! Then the new law came about a little later, forcing the legal age to 21. For some time there was a fight, N.O. did not want to comply. Howvever, you now have to be 21 to legally drink.

History of Drinking Regulations. For almost 40 years, most states voluntarily set their minimum drinking age law at 21. But at the height of the Vietnam War in the early 1970s, 29 states began lowering their drinking age to more closely align with the newly reduced military enlistment and voting age. And of those 29 states, no uniformity in age limits—drinking ages varied from 18 to 20. The results of this natural experiment were fairly immediate. The decrease in the drinking age brought about an increase in alcohol traffic fatalities and injuries. So much so that, by 1983, 16 states voluntarily raised their drinking age back to 21—a move that brought about an immediate decrease in drinking and driving traffic fatalities incidents.

In 1848, the drinking age in Louisiana was 18, and it was raised to 21 in 1987, but it was really 18 until 1995 because of a loophole in the state. The age was raised to 21, and the loophole was closed in 1995. For a short period of time, it was lowered to 18 by the Louisiana Supreme Court, but they reversed their decision, and they brought the drinking age back up to 21 three months later. There are other exceptions in the state still.

Best Answer: The other answers are correct and it is now age 21. However, you may encounter someone who insists it is age 18 because they once legally bought alcohol in a bar in LA as an 18, 19, or 20 year-old. They aren't lying or wrong, but their information is outdated.

I don’t know how it is today but I found that even after the drinking age was raised to 21 in Louisiana (just as I turned 18), bars in New Orleans still didn’t check IDs for the most part. My friends and I went there for the sole purpose of hitting Bourbon Street in our late teens with no problem (around 1996-1998).
