The British government has provided a fund of 500, 000 pounds to develop the world's first vehicle made from hemp.
The joint project between the environment department DEFRA, car giant Ford and growers Hemcore aims to create new materials based on plant fibres to replace metal and oil-based plastic components.
According to the Sun, developers Qinetiq have already designed hemp replacements for the accelerator, brake and clutch pedals.
They have said with improvement in technology, it might also be used for larger car parts such as body panels.
The parts can also be recycled, they have said. But Friends of the Earth have said using drug-free hemp — which is linked to cannabis and contains its active ingredient THC — wouldn't make much difference to the environment.
"The real problem is there are too many cars burning too much fuel," said FoE.
