Hemp has been legal at a federal level in the U.S. since December 2018. Some states, however, try to prohibit the use of smokable hemp due its physical and aromatic likeness to cannabis and the difficulty it’s causing law enforcement in telling the two apart.

However, it is proving difficult for states to go against the federal regulations and many lawsuits against states are taking place right now. Compliant online retailers of hemp flower, like Green Unicorn Farms, can sell and ship hemp products to all 50 states.

In order to be compliant with federal law, the hemp plant needs to contain no more than .3% Delta-9 THC.
