Federal prosecutors in Colorado want to take ownership of luxury cars, homes, watches and more than 1,000 pot plants seized from marijuana growers accused of illegally growing pot and sending it to Florida.

A forfeiture lawsuit filed Thursday involves a case authorities say represents the growing problem of illegal traffickers cultivating weed among Colorado's sanctioned pot warehouses and farms then illegally shipping to other states, where it can sell for more than double what it fetches in a legal Colorado shop.

Authorities in September arrested 20 people, many of them Cuban, accused of buying properties in rural southern Colorado to illegally grow and sell pot.

The court filings offer a glimpse into how lucrative such an enterprise can be. Investigators confiscated more than $30,000 in cash and dozens of firearms.
