The Reliability of Hair Follicle Tests in Detecting THC

Those with higher levels of fat content store cannabinoids more readily than leaner folks. Once a specific test is selected, the experimenter must then choose its sensitivity, or the cutoff concentration of THC-COOH above which a test is considered positive. Sebum excretions of the skin are just one way THC can leave the body, making hair collection and testing one of the most common ways to test for cannabis use. THC can remain traceable in the hair for up to 90 days and sometimes longer. CBD is unlikely to trigger positive drug test results, but users should still be mindful of the type of products they are using to make sure no amount of THC is present.

• As I’ve indicated earlier, THC does linger in hair follicles for up to three months.
• These metabolites remain in your system long after weed’s effects have worn off.
• This is not only true of different categories of drugs — such as alcohol and benzos — but also of different agents within each category.
• There are many different kinds of drug tests available, which have varying levels of sensitivity and time periods to detect marijuana in your system.
• How one’s body processes THC is often unique and highly dependent on individual metabolism.
• The hair sample is rinsed and treated with organic solvents to rid it of external contaminants.

Factors Affecting Weed Detection

Marijuana drug screenings and testing have been commonplace for decades. With the rise in alt-cannabis products like CBD, Delta 8 and Delta 9, more individuals are worried about testing positive for marijuana. “Diet weed” options might seem safe until faced https://ecosoberhouse.com/ with a potential drug test. Because of this, very little data points to how much CBD stays in your hair and the length of time it remains there. Hair strand tests do, however, detect THC metabolites, which are detectable in hair for up to 90 days.

What About CBD and Hair?

However, many CBD products like CBD oil contain tetrahydrocannabinol (THC), marijuana’s psychoactive ingredient. High enough THC levels will, unfortunately, result in failed drug tests. However, a 2017 study looking at oral fluid CBD concentrations in occasional and frequent users after smoking cannabis noted that CBD had a 2.5 to 4-hour detection window.

Most testing agencies, however, will screen for these compounds and being caught is often just as bad, if not worse, than a positive test. Many who are facing a drug test but are unwilling to fully give up cannabis turn to synthetic cannabinoids in the hopes of cheating traditional tests. And many private companies now include tests for synthetic cannabinoids in their repertoire, making this approach both dangerous and futile. Flegel also notes that he often sees cases where individuals fluctuate between positive and negative tests for marijuana over a period of time. This is drawn out to around one week for a more sensitive 20 ng/mL threshold. THC metabolites stay in the body for at least 1–30 days after use.

• Our bodies are designed to break down and remove substances like THC in unique ways, largely based on factors such as age, gender, and overall health.
• For example, anecdotal reports suggest mangoes can have this effect.
• Flegel also notes that he often sees cases where individuals fluctuate between positive and negative tests for marijuana over a period of time.
• If your urine is diluted too much, however, it will automatically invalidate the results and you will have to repeat the test.
• However, this initial “false positive” would not hold up to the more rigorous second round of confirmatory testing, which specifically measures THC-COOH.
