Members of the New York delegation on Thursday urged the Justice Department to allow the state to import medical marijuana for children suffering from seizure disorders.

The lawmakers said the treatment, an extracted oil called cannabidiol, can help children with epilepsy or other disorders that aren't helped by other treatments.

In a letter to Attorney General Eric HolderEric Himpton HolderComey's book tour is all about 'truth' — but his FBI tenure, not so much James Comey and Andrew McCabe: You read, you decide Eric Holder headed to New Hampshire for high-profile event MORE, the lawmakers requested a way for New York to import the drug.

"Every day makes a difference for children with these severe disorders. Given this urgent public health need, we urge you to allow New York the ability to import finite and strictly controlled amounts of cannabidiol," they wrote.

New York recently legalized access to medical marijuana, but it will not take full effect until January 2016. The bipartisan group of 18 lawmakers say that New York should be able to import medical marijuana from other states in the meantime.

"During this interim period, many New York families are struggling to treat children with conditions like refractory epilepsy that have been shown to be responsive to cannabidiol," they wrote. "Because cannabidiol is not yet available in New York, the state is seeking other options to bring relief to these families and children."
