Indoor Science has been deemed an essential service and is open for all services, including COVID consulting work.



If you suspect a previous homeowner or tenant manufactured or used drugs in your property, Indoor Science can test surfaces to detect the remaining presence of these chemicals.  Drug contamination from the use or manufacture of methamphetamine, fentanyl, and other substances can make some environments hazardous or uninhabitable. Other drugs such as marijuana may not have health effects that are as severe, but the odors can be a large nuisance. Reach out to us at 312-920-9393 if you suspect drug contamination at your property. 


Methamphetamine is a powerful stimulant also known as meth, ice, speed, crank, and various other colloquial terms. The substance is typically manufactured in clandestine laboratory locations which can be at a property, in a mobile lab such as a vehicle, or in an outdoor setting. According to the Illinois Department of Public Health, methamphetamine is made by using the over-the-counter drugs ephedrine or pseudoephedrine in conjunction with other chemicals. Indoor Science has been able to find the presence of meth on surfaces. In one case, a client had methamphetamines show up in a blood sample and suspected previous drug usage in their property. Our tests of the surfaces showed an elevated level of meth on surfaces, with the highest levels in the bedroom.


Marijuana, also known as cannabis is a plant with psychoactive properties. Marijuana was legalized for recreational use in the state of Illinois on January 1, 2020. The primary psychoactive compound in marijuana is tetrahydrocannabinol (THC). This compound is what produces the euphoria or “high” for recreational users. Marijuana smoke, especially those with a pungent “skunk” odor, can cause complaints among neighbors. Indoor Science can document that marijuana smoking has occurred by detecting THC on surfaces.

Other Drugs

At Indoor Science, we can test for various other illicit substances such as Cocaine, Fentanyl, MDMA (Ecstasy), and LSD. These drugs, along with methamphetamine and THC, can be tested together, possibly requiring the collection of only one sample.

Drug Testing – How is it Done?

Drug sampling is typically done by collecting a wipe sample on surfaces thought to be affected by drug contamination. Samples can be collected on a single surface or composited along a larger homogenous area. Generally it is better to take different samples on individual surfaces rather than taking one sample composited over multiple surfaces.  For example, if there is only contamination on 1 of 3 surfaces sampled, the two “negative” surfaces can dilute the presence of the drug, possibly below the limit of detection.  It would be preferable to collect separate samples on those three surfaces, which can also help target cleaning activities.

What Does it Cost?

At Indoor Science, the price for drug testing can range depending on the number of drugs being tested for and the number of samples collected during the assessment. The starting price for drug sampling is around $600. Sample results are typically available about 2 weeks after sample collection. Call Indoor Science at (312) 920-9393 to describe your drug concerns.
