Cannabis-munching cows to get change of diet in Alpine state

Farmers in Liechtenstein æwill no longer be allowed to feed cannabis to their livestock under new rules to be introduced in March in the tiny Alpine state.

Hemp — of which the marijuana plant is a well-known variety — contains small amounts of THC, the active substance in hashish, and traces of the drug have been filtering through to the milk of dairy cows fed with the plant.

The levels breach the maximum limit set by the new rules, which say that animal feed must be free of any component that could have an adverse effect on humans, the country’s veterinary and food controls office said in a statement.
