INDIANAPOLIS (AP) — A new report from Indiana State Police says the state's police agencies seized more than 1,800 methamphetamine labs last year.

The report released Friday says the number of meth labs raided by Indiana police agencies has grown for seven straight years despite the passage and strengthening of state laws restricting sales on cold medicine used to make meth.

The number of meth labs seized by Indiana police agencies had dropped to 803 in 2006, but has risen every year since.

The new report says the vast majority of homemade meth is made in volatile “one-pot” concoctions mixed in soda bottles, rather than in backwoods labs.

The National Institute on Drug Abuse says most of the meth sold in the United States is made in so-called “superlabs,” most often in Mexico.
