Cannabis use is detectable with hair tests and is generally included in the standard hair test. Hair tests generally take the most recent 1.5 inches of growth and use those for testing. That provides a detection period of approximately 90 days. [5] If an individual's hair is shorter than 1.5 inches, this detection period will be shorter.
Chemical hair analysis is used for the detection of many therapeutic drugs and recreational drugs, including cocaine, heroin, benzodiazepines and amphetamines. [3] [4] Hair analysis is less invasive than a blood test, if not quite as universally applicable. In this context, it has been reliably used to determine compliance with therapeutic drug ...
Compared to cannabis plants from the two other categories, an Indica marijuana plant usually grows to have a dense and bushier structure with broader and usually darker leaves. Indica cannabis ...
Cannabis plants are broadly covered with sessile glands, and other hairs throughout above-ground portions of the plant. There is a particularly high concentration of glands on the bracts of the female plant. After flower formation begins, some of the glands, especially on bracts near the flowers, develop stalks projecting them outward from the ...
The authors themselves reported that the D–L test gave false positives, but declared the D–L test confirmatory when combined with the presence of cystolithic hairs, which marijuana plants possess. However, many plant species have such hairs, and the study only confirmed that 82 of them did not give D–L test false positives.
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...
The darker and coarser the hair the more drug that will be found in the hair. If two people consumed the same amount of drugs, the person with the darker and coarser hair will have more drug in their hair than the lighter haired person when tested. This raises issues of possible racial bias in substance tests with hair samples. [13]
