Protesters turned out on Amsterdam's central Dam Square on Saturday, hoping to stop the government from banning magic mushrooms and asking to "save the 'shrooms".
Carrying banners reading "When will they ban bread?" and "Boss of your own brain", more than 100 people, some wearing hats resembling the bright red cap of the popular fly agaric variety, protested to keep hallucinogenic mushrooms legal.
After several incidents involving tourists -- in March, a French teenager jumped to her death from a bridge after taking mushrooms -- the Dutch government plans to ban them.
Arno Adelaars, author of a book on magic mushrooms, said this would only drive users underground and what was needed instead was better information how to use mushrooms right.
