How Long Does Weed Stay in Your Hair?


If you smoke marijuana, you know that no matter how much you enjoy the benefits of weed, the possibility of testing positive on a drug test will make you second guess your consumption habits. Urine, blood, and saliva tests are typically the most common types of drug testing conducted; however, some governmental organizations or law enforcement positions request more accurate testing to identify whether an applicant has a long-term history of drug use. Many people fear hair follicle drug tests, and with good reason. Evidence suggests that hair follicle drug tests are by far the most accurate at detecting cannabis use and the best for identifying whether an individual has a history of use.

Hair follicle drug tests help detect Tetrahydrocannabinol (Delta-9-tetrahydrocannabinol) or THC in the system much, much further back. No other test compares to the effectiveness of determining long-term use as the hair follicle drug test. Salvia drug testing may be more common and effective for determining very recent use, while urine and blood drug tests will be most accurate at detection within days/weeks of use.

The two compounds you should be familiar with are THC and 9-carboxy-THC. The signature chemical present in marijuana is THC, which many associate with the high felt after consumption. Metabolites, by-products of the process of THC breaking down, such as 9-carboxy-THC, are chemical compounds that stick in the fatty tissues, thus meaning the process of metabolization takes much longer.

With 7 days of use, you can detect these by-products in a follicle hair test. The metabolites in the body will pass first through the bloodstream and then to the hair follicle; many sources concur that the detection of these metabolites will be possible up to even 90 days after marijuana use.
