Bolivian Coca leaf growers clashed with police in La Paz’s main coca market, Adepcoca.

About 90% of Bolivia's legal coca passes through Adepcoca, according to the United Nations and coca growers are fighting over who should control the market.

The disputes involve two groups, one loyal to the government and another loyal to the opposition.

Bolivia's legal coca leaf business is worth $173 million a year.
