Colombia's Farc rebels propose regulation of drug production

Colombia's largest left-wing rebel group, the Farc, has presented its proposals to regulate drug production. The regulation plan as part of the Farc's peace talks with the government. 
    
The guerrilla group, which largely finances itself  through drug trafficking, is suggesting a programme to regulate the production of  coca, poppies and marijuana. 
    
The rebels said growers should be enticed to voluntarily grow alternative crops.
    
In addition to cocaine, for which is Colombia is most known, the Farc grows large amounts of  marijuana and produces smaller quantities of  heroin. 
    
The government has spent millions of  dollars trying to eradicate illicit crops - pulling them out by hand, spraying them with herbicides, and encouraging growers to switch to legal alternatives. 
    
According to United Nations figures, Colombia has seen a 25% fall in the area of  land planted with coca during 2011 and 2012. 

The United States has spent billions of dollars assisting the Colombian Government in its fight against the drug cartels and rebel groups, under a programme dubbed Plan Colombia.
