Every year, thousands of teens flock south of the border to enjoy spring break and take and advantage of the lower drinking age, but this year's plans could be swept out to sea.
To combat high rates of alcoholism, the Mexican Health Ministry is pushing to raise the legal drinking age from 18 to 21.
Mary Snyder, who works to promote tourism in the northern state of Sonora said in towns like Rocky Point, tourism has evolved so the new law would have a minimal impact.
"It wouldn't affect it extremely," she said. "Other than the couple times in the year the kids choose to come down here."
Snyder said it may affect some students' spring break plans, but the overall affect on Mexican tourism would be minimal.
"I can't say it wouldn't affect those weekends, but it doesn't affect year-round tourism."
The measure still has to be passed by the Mexican government.
