Pot-pipe residue mystery
pot pipe resin - Google Search
This Google Search produces the madness of potheads textually shouting contradictory opinions at each other regarding whether marijuana-pipe residue is valuable and contains THC, all without bothering to present or search for evidence. These opinions were based on personal experience or what someone had told them. The consensus opinion, was that pot-pipe residue does not contain THC and contains only tar, which offended my common-sense.
The pipe-residue is produced from the smoke passing through the pipe, why then should it be assumed that the residue contains only some elements of the smoke whilst magically excluding other elements?
Example of profound stupidity: several potheads claimed that when the herb is burned, this destroys the THC and so therefore no THC can be found in the pipe-residue! How then do these idiots explain how THC exerts its adored effects upon them, if it is destroyed before it passes out of the pipe and into their miniature minds?
"pipe residue" thc - Google Search
By way of contrast this Google Search produces solid scientific evidence re whether pipe-residue contains THC (plus other interesting info as a spinoff). The fact is that my common-sense was correct: there is more THC in pipe-residue compared to the herb itself (interpreting evidence I have seen thus far).
Yea, the pot-pipe resin Google Search produced many examples of potheads acting like fools. However, they probably would act like fools anyway in the absence of pot. When I read posted opinions at sites featuring the usual normal nation-wide type percentage of readers being potheads, I encounter the same kind of clash of opinions based on personal experience, minus evidence or logic.
Generally IMHO as of now: people are mentally immature regardless of whether they smoke pot or not. The mature minority become smart by carefully and thoughtfully using search terms that produce scientific evidence, like "pipe residue", and "THC". The immature majority lives in a world of slang-words like "pot", and "resin". The immature majority wastes incredible amounts of its time textually proclaiming or listening to opinions based on personal experience or hearsay. The mature minority learns how search terminology can mean the difference between light and darkness.
"pipe residue" thc - Google Search: Some (expertly!) condensed search results (point is, my ability to condense text in and of itself, even aside from my top-1% standardized text scores, justifies big paychecks for me!):
...Harold Riddle, a chemist with the Kansas Bureau of Investigation (KBI), testified that he conducted several forensic tests on the blue metallic pipe... Riddle "detected...THC... in the residues [sic] of the pipe." ...Riddle testified as follows: "...the tests which I performed were to first take an extract of the residues [sic] in the pipe... I performed a thin-layer chromatography test, a Duquenois-Levine, or a color test, and then also a gas chromatography mass spectrometry test, ...

Two ceramic pipe bowls, excavated... in...Ethiopia (near Lake Tana), were tested...The pipes... (had a) radiocarbon date of l320 ± 80 A.D...This date is clearly earlier than the introduction of tobacco to Africa from the New World, following Columbus' journey. Archaeological remains ...differ but little from the present-day material culture of the region...workmen...were able to identify the pipe bowls and their mechanical operation. Both bowls formed part of waterpipes...Pipe B2 ...contained a "pipe-cake" as thick as 1 mm in places...Pipe A2 ...contained only a small amount of residue....A standard thin-layer chromatographic technique, used in hospital and police testing...was used in the experiment...several modern pipes which had previously tested positively for cannabinolic compounds were used for comparative purposes. The THC standard and the modern pipes exhibited the familiar spot for THC, cannabinol, and cannabidiol...the modern pipes exhibited faint spots at Rf values of 0.69 and 0.84, as did pipe B2 .... We conclude that THC, cannabinol, and cannabidiol have relatively short lifetimes and cannot be identified in ancient samples. (A figure of 50 years (lifetime) is often mentioned, but remains untested.) When subjected to the heat of smoking, however, one or more of these compounds degrade to form two unidentified cannabinoids, with Rf values of 0.69 and 0.84, and lifetimes in excess of 500 years. The presence of these cannabinoids in a pipe positively identifies its use for the smoking of Cannabis sativa...Archaeologically, we conclude that some variety of Cannabis saliva was smoked around Lake Tana in the 13th-14th century...How and when the plant...reached this area is unknown; an Arabic source seems probable....

...Cannabis sativa...three genotypes:1. the resin plant is rich (>1%) in THC [q.v.], with significant amounts of CBD (Cannabidiol) 2. the hemp fibre plant has low (<0.3%) THC but CBD is essentially absent; 3. an intermediate variety, growing in certain climates... Smoking Residues The partially pyrolysed residue in a pipe bowl or cigarette butt may still retain some herbal features but is conveniently regarded as a crude specimen of ‘separated resin’. Thus, the act of smoking has thermally ‘separated’ the resin from (herbal) cannabis. The residue may be richer in THC than the original herb through thermal decarboxylation of precursor acids [see next section]...In Bocking v Roberts,as little as 20 micrograms of cannabis resin residue in a pipe, estimated colormetrically,supported conviction...in R v Carver (1978), it was established that 20 micrograms residue in a smoked ‘roach’ and 2 mg (2000 micgrogams) cannabis resin scraped from a box constituted an unusable amount
