What is a meth lab?

Meth "recipes" are easy to obtain from other cooks and from the internet. There are hundreds of chemical products and substances that are used interchangeably to produce meth. The substitution of one chemical for another in meth recipes may cause the cooking process to be more hazardous (resulting in fire or explosion) or may result in a finished product with unwanted or dangerous effects.

Many dangerous chemical ingredients are used to make meth. The cooking process causes chemicals and methamphetamine to be deposited on surfaces and household belongings. Also, chemical by-products such as toxic phosphine gas may be formed during meth manufacture. This may occur through planned chemical interaction, or by processing errors, such as increasing cooking temperatures too rapidly.

Every meth "recipe" starts with over-the-counter medications that include pseudoephedrine or ephedrine in their contents. The pills are crushed and mixed with other chemicals in the process of cooking meth. Various meth recipes include combinations of volatile organic compounds (VOCs), acids, bases, metals, solvents and salts. Making meth with these chemicals can result in explosions, chemical fires, and the release of toxic gases.

Meth cooking also produces solid and liquid waste that can contaminate a building and its contents, or the groundwater or soil where they are dumped.

What is Methamphetamine (meth)?

Methamphetamine, also known as "speed" or "crank," is a potent central nervous system stimulant. The drug is illegally produced in makeshift labs. The labs are set up at rental homes, apartments, mobile homes, motel rooms, garages, storage sheds, cars, campgrounds and various outbuildings. All of the processes that produce methamphetamine use a variety of chemicals including explosives, solvents, metals, salts, and corrosives. During the drug manufacturing process additional compounds and by-products are produced. Exposure to these chemicals can have various health effects on producers and others that are unintentionally exposed. Typically, after a lab is discovered by law enforcement officials, the bulk of lab-related materials including chemicals and containers are removed. However, small amounts of contaminants can remain on floors, walls, counters, carpets, furniture, sinks, drains and ventilation systems. Exposure to even small amounts of some of these chemicals can pose serious health risks.

Every pound of methamphetamine produced generates five or more pounds of hazardous waste. Much of this waste is dumped down drains and toilets or on the ground, creating many additional contaminated sites. Such dumping has created septic tanks full of dangerous waste and chemically-contaminated drain fields, soils and surface waters.


Methamphetamine affects your brain. In the short term, meth causes mind and mood changes such as anxiety, euphoria, and depression. Long-term effects can include chronic fatigue, paranoid or delusional thinking, and permanent psychological damage.

Methamphetamine affects your body. Over “amping” on any type of speed is pretty risky. Creating a false sense of energy, these drugs push the body faster and further than it's meant to go. It increases the heart rate, blood pressure, and risk of stroke.

Methamphetamine affects your self-control. Meth is a powerfully addictive drug that can cause aggression and violent or psychotic behavior.

Methamphetamine is not what it seems. Even speed drugs are not always safe. Giga-jolts of the well-known stimulants caffeine or ephedrine can cause stroke or cardiac arrest when overused or used by people with a sensitivity to them.

Methamphetamine can kill you. An overdose of meth can result in heart failure. Long-term physical effects such as liver, kidney, and lung damage may also kill you.


How do I recognize if someone is on meth?

Under the influence of the drug, users often become agitated and feel "wired." Their behavior becomes unpredictable. They may be friendly and calm one moment, angry and terrified the next. Some feel compelled to repeat meaningless tasks, such as taking apart and reassembling bits of machinery. Others may pick at imaginary bugs on their skin. Physical affects include: increased heart rate, blood pressure, body temperature, and rate of breathing; it dilates the pupils and may cause tremors. Encourage your friend to stop or seek professional help. For information and referrals, call the National Clearinghouse for Alcohol and Drug Information at 1-800-729-6686.

How do I recognize a meth lab?

Clues that may indicate illegal production or sales of drugs include the following:

Access denied to landlords, neighbors, and other visitors
"Cooks" have no visible means of support but make cash purchases and payments
Covering or blacking-out of windows
Other security measures such as cameras or baby monitors outside of buildings
Unusual traffic and activities, such as excessive night traffic or purchases taking place
Burn pits, stained soil or dead vegetation indicating dumping of chemicals or waste
Waste in trash, pits or piles, such as:
Packaging from over-the-counter ephedrine or pseudoephedrine cold, diet or allergy pills
Empty containers from: antifreeze, white gas, ether, starting fluids, freon, lye or drain openers, paint thinner, acetone, or alcohol
Compressed gas cylinders, or camp stove (Coleman) fuel containers
Packaging from epsom salts or rock salt
Anhydrous ammonia tanks; propane tanks or coolers containing anhydrous ammonia
Pyrex/glass/Corning containers, with dried chemical deposits remaining
Bottles or containers connected with rubber hosing and duct tape
Coolers, thermos bottles, or other cold storage containers
Respiratory masks and filters or dust masks
Funnels, hosing and clamps
Coffee filters, pillow cases or bed sheets stained red (used to filter red phosphorous), or containing a white powdery residue
Buildings that smell like chemicals, including sweet, bitter, ammonia or solvent smells.

What to do if you find a meth lab

An individual who believes he or she has discovered an illegal drug lab or the site of an abandoned lab should immediately notify local law enforcement (Dial 911) and should not enter the area of the suspected lab. Anyone who inadvertently enters a lab should back out immediately without disturbing the cooking process, chemicals or equipment. You can also report an illegal drug lab by calling the Madison County Sheriff's office at 828-649-2721. Or use our anonymous tip form.
