Did you know?


Before it got banned in the 1930s, hemp powered 80% of clothing—strong, sustainable, unmatched.

Then, in a blink…

Hemp was sidelined, victim to political greed and propaganda.

Their motive? 

Kill hemp, boost profits from cotton, timber, and synthetics–Now three of the world’s most polluting industries!

Their Playbook Used From The 1930’s Until The Tables Turned In 2018 and today:

17th-18th Century

Hemp's Golden Era: Fuels 80% of World's Textiles, Shipbuilding, and Exploration.

1935

George W. Schlichten patented first hemp decorticator machine to improve hemp processing.

1936

Anti-hemp propaganda launches to protect synthetic industry interests.

1937 Marijuana Tax Act

Penalizes hemp, crippling potential.

1970 Controlled Substances Act

Wrong classification sidelines benefits.

1980s-1990s

Legal restrictions overshadow eco-advantages.

2018 Farm Bill

Legalizes hemp, acknowledging safety and versatility.

2024: Undrdog

Boldly elevating men's fashion with premium shirts to restore hemp's heritage.
