If you live in the US then you definitely can't grow it (even many countries that do allow Hemp to be grown regulate it). In the US though we can buy and consume the raw hemp seeds (and other products) but I agree they probably won't germinate.

In the United States it is legal to only sell the cooked hemp seeds. In other words the hemp seeds you can buy can't germinate.
(Manitoba Harvest and Living Harvest both sell raw hemp seeds that are cold-processed to no-more than 40degree C (104 F) ).
That did make me interested as to why it wouldn't germinate (my assumption because it they are hulled) and I thought about doing an online search but then thought that maybe it would be interpreted as a search to learn how to grow Hemp so I decided against it.

So much for being free.
