Gov. Neil Abercrombie signed an industrial hemp bill into law Wednesday.
The measure makes it legal for the University of Hawaii to grow a field of the plants for research purposes.
The program will last for two years.
The crop is believed to be able to clean the soil that it grows in and be used for bio diesel. Lawmakers say Hemp could boost Hawaii's economy.
"This will create jobs for people. It's an entrepreneur's dream with 25,000 uses of industrial hemp – none of which get you high," said Rep. Cynthia Thielen.
UH says it's been given an area about the size of a football field to plant the crop on Hickam Air Force base.
The school will be required to report its findings to lawmakers in 2016.
