The study most cited in favour of the specificity of the D–L test is Thornton and Nakamura (1972). [5] 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 ...
The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 [clarification needed] different cannabinoids, such as tetrahydrocannabinol (THC), and 120 terpenes, [1] which allow its drug to have various psychological and physiological effects on the human body.
To administer the test, a user simply has to mix the chemicals with a particle of the suspected substance; if the chemicals turn purple, this indicates the possibility of marijuana.

Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, [ 53 ] and at least 85 different cannabinoids have been isolated from the plant. [ 54 ]
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [3] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
Watering frequency and amount is determined by many factors, including temperature and light, the age, size and stage of growth [22] of the plant and the medium's ability to retain water. A conspicuous sign of water problems is the wilting of leaves. [23] Giving too much water can kill cannabis plants if the growing medium gets over-saturated.
Lime water can make that a whole lot easier. A fresh-squeezed lime is “going to add about 11 calories to the water that you’re drinking, about 51 milligrams of potassium, less than 1 gram of ...
