Keep in mind that hemp is not the same as cannabis, same family different plant. Hemp has thousands of uses and is used to make everything from paper, food, clothing and even plastics. Has low to no THC if any, so it can't be used as a drug. Paper pulp made from hemp can be recycled 10 times more than wood pulp and can out produce cotton. Finished products can be sold here in the US, which includes hemp seeds but it can't be grown here. Hemp seed can be made into milk, flour, protein powder etc. the amount of THC is negligible. The US is so fanatical about saving the environment, but is so adamant about not letting any type of hemp be grown in the United States, why? Does that make the US government hypocritical, or does it just mean there on the take from major corporations? What US companies have been pushing to keep hemp in the same category as cannabis, when they clearly know that these are two different plants? Our first flags and our Constitution and Declaration of Independence were written on paper made not from wood pulp, but from hemp. Did our founding fathers know something we don't, or were they just less corrupt?
