As you can see "meth cookers" can produce large quantities of meth by using legal, over-the-counter products. If you suspect someone is involved in the illegal production of methamphetamine, please contact your local law enforcement agency or the Kansas Bureau of Investigation (KBI) at 1-800-KS-CRIME (800-572-7463. In addition, please contact the KBI if you see any suspicious persons around an anhydrous ammonia tank possessing a cooler or propane tank. A Suspicious Transaction Report Form (PDF) should be used to report suspicious activity.
