The obviously not mellow pothead was running from police when he lost control of his car and slammed into a tree.
Physics took it from there.
When his car came to a rather sudden stop the half-ton of weed in his back seat barreled forward and crushed him against his steering wheel and windshield, killing him.
The Daily Mail reports the three mile chase began when the man blew through a road block and cops took off after him.
Police in the Brazilian city of Bataguassu think the man was returning from Mato Grosso do Sul and headed to to Sao Paulo to sell the 1,100 pounds of marijuana.
