Cadets at the Air Force Academy are more straight and narrow than dazed and confused.

The Colorado Springs military academy earned top rankings in such categories as low marijuana usage, stone-cold sober schools and low hard liquor consumption in the Princeton Review's annual list of college rankings, released today.

"We don't have a much of a problem with drugs," academy spokesman Johnny Whitaker said. "Our alcohol policy is pretty strict too. You don't drink unless you're 21 and if you provide alcohol to someone underage there are very serious penalities, including disenrollment."

The academy was also rated No. 1 for the accessibility of its professors; 19th for most religious students and 11th for "Students most nostalgic for Ronald Reagan."

The academy's well-behaved student body did have complaints about the food, ranking the institution 11th for unappetizing cafeteria cuisine.

For the third year in a row, the University of Colorado at Boulder failed to make the Top 20 list of party schools. The school, however, was ranked 15th for "refer madness" or high marijuana usage.

The Princeton Review survey includes roughly 325 students at 366 schools nationally. The students are asked 80 questions about their institution's academics and administration, campus life, student body, and themselves.
