Does it produce seeds? Yes
Are these seeds a food source? Yes(in fact perfectly balanced for our needs.)
King James Bible (Cambridge Ed.)
And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat.

But the law is against it
I Timothy 4:1-3
“1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; 2Speaking lies in hypocrisy; having their conscience seared with a hot iron; 3Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth. 4For every creature of God is good, and nothing to be refused, if it be received with thanksgiving: 5For it is sanctified by the word of God and prayer.”
It is a plant so eating it or its seeds are not a sin even if you get high.
