You have to go to Norway to get one. Consider this:
A Norwegian witch has won a Â£5,000 [53,000 kroner] business grant from her government to make and sell magic potions.
Her specialty products include night creams for vivid dreams, a day cream to combat indecisiveness and a foot cream to change a user’s bad habits.
I guess it is better than burning them, but how about laissez-faire?
