Methamphetamine, meth-lab assessment and clean-up



The following discussion is adopted from the discussions by two individuals; excellent work done by Tracy Hammon with the Colorado Department of Health, and training materials provided by Caoimhín P. Connell, a consulting Forensic Industrial Hygienist.

This discussion has been prepared by Forensic Applications, Inc. (FACTs), an industrial hygiene consulting firm in Colorado that provides cursory meth-lab assessments for Realtors and home buyers, and full State mandated Preliminary Assessments, and Decision Statements (clearance and compliance statements).

FACTs also provides specialized law enforcement sensitive training as well as general public training on clandestine labs in general and meth labs in particular.

There is much on the internet concerning clan-labs and meth, and meth-labs. The objective of this discussion is to provide a very brief overview of meth and meth-labs followed by more detailed discussions of the hazards from the perspective of industrial hygiene, and law enforcement. The State of Colorado has the country's most concise and thorough regulations, and those regulations are discussed on a web site available by clicking here.

Underworld chemistry

What is Meth?

Meth is a chemical. It is a synthetic material, not found naturally occurring in nature. It has many street names, such as "crank," "ice," "speed," "glass," "tina," and "crack." For a larger list, see the table at the bottom of the page. Not all of these street names are unique to methamphetamine; some names can refer to more than one drug.

It also has a scientific name; actually, it has over 25 different "official" chemical names. Since many chemicals, like meth, have more than one official scientific name, each chemical is assigned a single and unique Chemical Abstract Registration Number (CASRN or CAS Number). This ensures that there is no confusion over the identity of a compound. The CAS for meth is 7632-10-2.

Generally speaking, there are three primary chemical forms of meth; only one is popularly abused; the form called dextro-methamphetamine (d-methamphetamine), which is the most potent and widely abused form of methamphetamine.

The chemical structure for meth is given below.

An isomer of the dextro-methamphetamine is called levo-methamphetamine (l-methamphetamine, a.k.a. deoxyephedrine).

Although l-methamphetamine is chemically identical to the d-methamphetamine, it's structure is different and therefore, the toxicological properties of l-methamphetamine are different. l-methamphetamine is an over-the-counter decongestant and is not a controlled substance, and not generally abused.

The third form is a mixture of the d and l forms, called a racemic mixture.

In Colorado, methamphetamine is a Schedule II controlled substance (CRS §18-18-204). The trade name of the drug is Desoxyn (methamphetamine hydrochloride tablets, USP).

Amphetamines are relatively new to the drug world. The Japanese are generally given credit for first synthesizing methamphetamine in 1919, and amphetamines in general, were freely marketed in the 1930 as the over-the-counter-drug "Benzedrine."

Indeed, the Japanese Kamikazes who were involved in the raid on Pearl Harbor were driven to their state of frenzy partially as a result of methamphetamine use.

What's a meth lab?

Generally speaking, there is a misconception that meth-labs and clan-labs are places filled with exotic glassware, rows of nicely organized chemicals and occupied by lab techs in white lab coats. Nothing could be further from the truth. Most of the operational meth labs we have experienced are filthy, chaotic, places of squalor; frequently strewn with faeces and urine.

Not all meth-labs or clan-labs produce methamphetamines or other illicit drugs. Some labs may only perform a specific step in the process. Generally speaking, clan-labs can be classified (by FACTs) as follows (for photos of various meth-labs click here.

Clan-Lab Classifications

Box LabsAreas where lab equipment is merely stored. These areas could include houses, sheds, boats, cars, or commercial storage sites.
Synthesis LabsThese are areas where controlled substances are actually produced.
Non-Cooking Operational LabsSynthesis labs that are "cold" and not actively in the process of manufacturing controlled substances
Extraction LabsSometimes the manufacturing and storage processes are broken into segments or cells. Extraction labs are places where only a partial step in the manufacturing process is carried out.
Conversion LabsSimilar to the "Extraction lab," "conversion labs" may be where a partial step takes place. Conversion labs, however may also be where raw or unrefined drug precursors are chemically altered into a new chemical that is used on the street as the final product. Examples would be: Morphine to heroin; Cocaine HCL to Cocaine base and Gamma-butyrolactone (GBL) to Gamma-Hydroxybutyrate (GHB)
Milling LabsMilling labs are locations where powdered controlled substances are "milled" into tablets. The term also applies to labs where tablets are crushed or "milled" (rendered into powder).
Rolling LabsRolling Labs are any of the above labs set in a mobile vehicle such as a train, car, RV, van, truck of car, etc.
Tinkle TweakersTinkle Tweakers are meth users who store their urine and faeces, and attempt to recover the un metabolized methamphetamine from those materials. We have performed activities in residences containing dozens upon dozens of 2 litre soft drink bottles filled with urine waiting to be processed. In such labs it would not be uncommon to find as much as 100 litres of stored urine.
Dirt BaronsDesperate as the Tinkle Tweaker may seem, other tweakers locate the illegal dump sites of other tweakers, and attempt to extract controlled substances from the dirt, and waste products dumped by previous manufacturers.

Where are meth labs found?

Everywhere. It's that simple.

Every neighborhood, rich and poor, across every ethnic, social and socioeconomic stratum.

There is no state in the union that is free from the scourge of the meth-lab.

The horror of meth abuse simply cannot be overstated.

Meth abuse consumes the quality of life and destroys people. In the series of photos below, the woman depicted was 38 years old when she died. Remarkably, she is actually alive in the last photograph. Each transition represents about 11 months.

Clan-labs are particularly hazardous places for the community, law enforcement personnel, and industrial hygienists required to enter the premises to perform risk assessment. Additionally, booby-traps and bombs are frequently found inside clan-labs which may pose a serious threat to remediation personnel hired to cleanup the property. For a discussion on how to recognize the signs of a former methlab click here.

Clan-lab Hazards

Hazard CategoryExamples
ChemicalsChemical vapors, gases, mists, and surface residues can all be present inside a meth lab of any description. Gases can include phosphine and acid gases such as hydrogen chloride and hydrogen iodide (hydrochloric acid and hydroiodic acid); anhydrous ammonia, metal hydrides, chlorine gas and hydrogen gas. Vapors include toluene, ether, iodine, MEK and gasoline. Acid and caustic mists include sulfuric acid mists, sodium hydroxide mists, phosphorous, and dusts of lithium, mercuric chloride, and others.

Needles are commonly hidden throughout a clan-lab; occasionally as APDs (see below) or simply stored out of the way by a tweaker and then forgotten. Extreme caution needs to be exercised and a constant threat of sharps needs to be considered.

TraumaClan-labs can be crowded places jam-packed with exposed hot-plates, distillation columns, and glassware.

WeaponsWhere there are controlled substances, there are weapons; guns, knives, hatchets, and swords. The spectrum and quantity is limited only by one's imagination. If one ever doubted that the thousands of gun laws in the US are ineffectual, one need only to visit a meth lab and see the quantity of weapons possessed illegally by criminals.
CriminalsBy definition, law abiding citizens do not manufacture controlled substances at home. When real estate professionals, or industrial hygienists, or remediation contractors enter into the realm of the meth lab, they are entering into an element of the criminal world, and the associated deceit and violence that accompanies that culture. During our assessments of methlabs, we have frequently encountered armed criminals who have illegally entered the locations.
Anti-personnel devices, APDsBooby-traps. Unlike other hazards faced by industrial hygienists, these are NOT passive hazards. These are clever, resourceful ways to hurt, maim or kill people who enter the meth-lab area. Simple examples include bottles of acid falling into cyanide powder, Al or Mg bombs (photo flash and 9v batteries), pipe bombs, venomous snakes, trip wired explosives, etc. In one lab in California, the entire concrete floor was cantilevered in the center, and under the floor was a 700 pound bomb. As part of our training in the detection of such booby traps, our personnel have attended law enforcement sensitive courses developed to teach officers how to manufacture such destructive devices.
Fires and explosionsWhite phosphorous, explosive concentrations of organic solvents, makeshift electrical wiring, conspire to produce an environment particularly susceptible to fires and explosions.

At the present time, the regulatory arena for the cleanup of meth labs is a patchwork of hit-and-miss standards. Most of these state promulgated standards are based on arbitrary values. Only the State of Colorado has established clean-up levels based on a sound scientific thought-process supported by state of the art industrial hygiene practices.

Of particular concern is the exposure to children in the home. Similar to cocaine and marijuana, the scientific and medical literature contain much about in utero (prenatal) exposures to methamphetamine, but there is little available toxicological and epidemiological data involving post natal exposures. Prior to the Colorado regulation, seminal work by the State of Washington laid the foundation for clean-up standards used by other states. Faced with the absence of reliable toxicological data, Washington promulgated a clean-up standard for methamphetamine in residential homes based not on classical risk-benefit toxicological risk assessments, but rather on the rationale that "the process of reducing levels of known contaminants to the lowest practical levels using current available methods and processes"1 in the face of unknown risks to infants crawling on carpets was prudent.

It is well established that the precursors and reagents used in clandestine methamphetamine production pose extremely dangerous conditions. However, some studies have demonstrated that up to 5,500 micrograms per cubic meter of air (ug/m3) which is equivalent to 5.5 milligrams per cubic meter of air (mg/m3). Further, those same studies indicate that as much as 16,000 micrograms of methamphetamine per 100 square centimeters (ug/100cm2) may be deposited on surfaces. "1a

However, the industrial hygiene and medical communities are now beginning to realize that the mere use of methamphetamine in homes also results in elevated exposures to children. When methamphetamine is smoked, between 80% 2 and half3 of the substance is released from the user's pipe. Of that material which is released, the drug is readily available to be absorbed into the body; between 67%4 and 90% 5 of the nominal dose is absorbed into the body. Recent work by industrial hygienists at the National Jewish Hospital 6 indicate that a single use of methamphetamine, by smoking, would result in an average residential area ambient airborne concentration of methamphetamine ranging from 35 micrograms per cubic meter (ug/m3) to over 130 ug/m3. These authors found that smoking methamphetamine just once in the residence will result in the air and surfaces being contaminated with methamphetamine and occupants will be exposed. The authors concluded: "If methamphetamine has been smoked in a residence, it is likely that children present in that structure will be exposed to airborne methamphetamine during the "smoke" and to surface methamphetamine after the 'smoke.'7 As a certain As Dr. Kathryn Wells succinctly stated:8

There are several aspects of child abuse and neglect in drug-endangered homes. The environments themselves are frequently so dangerous that simply allowing a child to live there constitutes child endangerment.

Below are some of the cleanup standards, excluding Colorado, current as of May 1, 2005. We recognize that some of the referenced items are contradictory with other available documents with those states. Remarkably, officials at those states were unable to resolve the discrepancies regarding their regulations. We have been informed that where discrepancies exist, they also exist in official documents.

State Regulations

StateSurface Cleanup Level
Alaska, Arizona, Minnesota, Tennessee, Washington0.1ug/100cm2
Arkansas, Oregon0.05 ug/100cm2

Some of the finest work in modeling risk and exposures to meth in meth labs was done by Tracy Hammon, a Toxicologist with the Disease Control and Environmental Epidemiology Division for the State of Colorado. Hammon's toxicological exposure model used to support the cleanup thresholds can be found by clicking here. The criteria document is titled SUPPORT FOR SELECTION OF A CLEANUP LEVEL FOR METHAMPHETAMINE AT CLANDESTINE DRUG LABORATORIES, February, 2005. That document describes in detail an exposure model that was instrumental in evaluating exposures. Briefly, in the State of Colorado, the mandatory cleanup levels for meth labs is:

1) Surface wipe samples and vacuum samples for meth shall not exceed 0.5 ug /100 cm2
2) If remaining materials are contaminated with iodine surface wipe samples shall not exceed 22 ug/100 cm2
3) If the preliminary assessment indicates the P2P method was used, surface wipe samples for lead shall not exceed 4.3 ug /100cm2
4) And vapor samples for mercury shall not exceed a concentration of 1.0 ug/m3.

Additionally, according to the Colorado regulation, the remediation must be based on a preliminary assessment that can only be performed by an industrial hygienist, as that term is defined in State Statute (CRS §24-30-1402). It is a misconception that only a certified industrial hygienist can perform the assessment. Indeed, at the final hearings, the Board of Health specifically expressed the opinion that too much emphasis was placed on the ABIH certification in industrial hygiene and that such certification was no guarantee the industrial hygienist was competent in performing the required assessment. Furthermore, just because a consultant is an bona fide industrial hygienist, does not mean they are authorized to perform the work; since not all industrial hygienists meet the training requirements of the regulation. State regulation protects consumers from these problems by requiring the industrial hygienist to provide the property owner with a "statement of qualifications" which is an affidavit attesting to the industrial hygienist's ability to perform the work. (To view a copy of our statement of qualifications click here).

Readers interested in state-of-the-art meth lab remediation should reference the above mentioned criteria document as well as a copy of the Colorado State Board of Health Regulations Pertaining to the Cleanup of Methamphetamine Laboratories (6 CCR 1014-3).

Forensic Applications, Inc. provides meth-lab hazard assessments and closeout verification for homeowners, building owners, law enforcement agencies, and realtors. Additionally, we provide meth-lab training to cleanup contractors, building maintenance personnel and other private individuals in need of training that is compliant with OSHA regulations (specifically 29 CFR 1910.120, the “HazWoper” standard, and 29 CFR 1910.1200 the Hazard Communication standard – and the Construction Industry equivalents found under 29 CFR 1926).

Some of our training is federally funded HIDTA certified meth lab training for law enforcement EMS, fire, and other first responder personnel. This training is provided through The Colorado Regional Community Policing Institute (created by the Colorado Department of Public Safety, Division of Criminal Justice) and is funded by the U.S. Department of Justice, Office of Community Oriented Policing Services (COPS). The training is provided at no charge or minimal charge to authorized personnel.

Law enforcement agencies and private entities alike can call upon our HIDTA certified law enforcement officer for assistance in conducting break-downs and addressing in situ active cooks, including participating in the actual tactical approaches, and clearance of the buildings.
