Question 1

True or false: Eating hemp seeds can cause a false positive on a drug test for THC.

Accepted Answer

False. Hemp seeds contain only trace THC (under 0.3%), far too little to cause a positive drug test unless consumed in absurdly large quantities.

Question 2

True or false: Hemp cannot be grown legally anywhere in the United States.

Accepted Answer

False. The 2018 Farm Bill legalized hemp cultivation federally, though states regulate it individually; it's now widely grown across the U.S.

Question 3

True or false: Hemp and marijuana are the exact same plant species with no differences.

Accepted Answer

False. Both are Cannabis sativa, but hemp has negligible THC (under 0.3%) and is bred for fiber, seeds, and oil, not psychoactive effects.

Question 4

True or false: Hemp plants require massive amounts of water to grow, similar to cotton.

Accepted Answer

False. Hemp is actually drought-tolerant and needs significantly less water than cotton, making it a more eco-friendly fiber crop.

Question 5

True or false: Hemp can be used to make biodegradable plastics and even concrete-like building materials.

Accepted Answer

True. Hemp hurds (the woody core) are mixed with lime to create 'hempcrete,' a lightweight, insulating building material, and bioplastics from hemp oil.

Question 6

True or false: Hemp seeds are a complete protein source, containing all nine essential amino acids.

Accepted Answer

True. Unlike most plant proteins, hemp seeds provide all essential amino acids, making them a rare complete plant protein—great for vegans.

Question 7

True or false: Hemp oil can be used as a biofuel that burns cleaner than petroleum diesel.

Accepted Answer

True. Hempseed oil can be processed into biodiesel, which produces fewer emissions and is renewable, though not yet commercially widespread.

Question 8

True or false: Hemp was one of the first plants ever spun into usable fiber over 10,000 years ago.

Accepted Answer

True. Archaeological evidence shows hemp fiber was used in ancient China and Mesopotamia as early as 8,000 BCE for textiles and rope.
