As the MLDA was still left to the discretion of the state, the act did not violate the 21st amendment which reserved the right to regulate alcohol for all responsibilities not specifically appointed to the federal government to the states. However, as the act controlled the distribution of anywhere from $8 million to $99 million, depending on the size of the state, the act gave a strong incentive for states to change the drinking age to 21. By 1995, all 50 states, two permanently inhabited territories, and D.C. were in compliance, but Puerto Rico and the Virgin Islands (and Guam until 2010) remained at 18 despite them losing 10% of federal highway funding.
