Le THC ou tetrahydrocannabinol hmoov yog ib qho tseem ceeb ntawm cov molecules nquag ntawm cannabis. Qhov no yog ib cannabinoid. Nws tau kwv yees tias "sib koom" muaj 2 txog 20 mg ntawm THC thiab thaum nqus tau 15-20% ntawm THC hauv cov pa luam yeeb nkag mus rau hauv cov ntshav.

Nws tseem tuaj yeem kuaj pom hauv cov qaub ncaug, zis, plaub hau, plaub hau ntawm lub cev, thiab lwm yam.

Qhov kev puas siab puas ntsws cuam tshuam ntawm cannabis tseem nyob ntev txog 12 teev, nyob ntawm kev noj thiab kev nkag siab ntawm cov ncauj lus.

Lub qhov rai pom tau ntawm THC yog li ntawd nyob ntawm lub hnub nyoog, qhov tseem ceeb thiab kev noj haus tsis tu ncua.

Nco ntsoov tias ib zaug hauv lub cev, THC tau tawg ua ob yam sib xyaw, 11OH-THC thiab THC-COOH. THC tuaj yeem kuaj pom hauv cov ntshav li ob peb feeb tom qab thawj nqus dej, qhov siab tshaj plaws ntawm 11OH-THC tau mus txog kwv yees li 30 feeb thiab qhov siab ntawm THC-COOH tsawg dua 2 teev.

Tom qab siv cannabis, feem ntau yog nqus pa, THC tuaj yeem kuaj pom sai sai hauv cov ntshav. Nws lub xub ntiag tseem tuaj yeem kuaj pom hauv cov zis thiab qaub ncaug. Yog li THC yog siv los ua tus cim txhawm rau txheeb xyuas kev noj cannabis, feem ntau hauv cov txheej txheem tshuaj (txoj kev raug xwm txheej, kev tsis txaus ntseeg ntawm kev siv tshuaj, thiab lwm yam) lossis kev tshaj lij (tshuaj ua haujlwm).

Ntau qhov kev xeem raug siv, nyob ntawm cov ntsiab lus:

• kuaj ntshav : nws ua rau nws muaj peev xwm txheeb xyuas kev noj cannabis hauv ntau tshaj 2 txog 10 teev tom qab noj nws (THC, 11OH-THC thiab THC-COOH tau nrhiav). Qhov kev xeem no zoo dua thaum muaj xwm txheej xwm txheej, piv txwv. Nws yog siv los kwv yees lub sijhawm dhau los ntawm kev siv zaum kawg thiab kuaj ntshav. Thaum qhov siab ntawm THC siab dua li ntawm 11OH-THC, nws qhia txog kev noj los ntawm nqus pa. Qhov rov qab yog pov thawj ntawm kev noj los ntawm kev noj. Tom qab 3 txog 4 hnub, cannabinoids raug tshem tawm tag nrho los ntawm cov ntshav.
• kuaj zis (THC-COOH): nws ua rau nws muaj peev xwm txheeb xyuas kev noj haus qee zaum txog li 2 txog 7 hnub tom qab, thiab txawm tias ntev dua nyob rau qhov xwm txheej noj tsis tu ncua (7 txog 21 hnub, lossis ntau dua).
• ntsuam xyuas qaub ncaug (THC): qee zaum nws tau siv los ntawm cov koom haum tub ceev xwm los tshuaj xyuas cov tsav tsheb. Nws tuaj yeem txheeb xyuas kev noj haus txij li 2 txog 10 teev. Txawm li cas los xij, tsis muaj kev pom zoo ntawm nws qhov kev ntseeg tau zoo (muaj nyob ntawm qhov tsis zoo).

Hauv cov plaub hau (feem ntau yog thaum kuaj mob), tuaj yeem pom ntau lub hlis lossis ntau xyoo tom qab (cov plaub hau loj hlob nruab nrab ntawm ib cm / hli thiab cov cim ntawm THC tsis ploj).

Xijpeem ntsuas tau ntsuas (ntshav, zis lossis qaub ncaug), nws muaj hauv kev kuaj pom, ua tsaug rau kev siv tshuaj tiv thaiv THC tiv thaiv kab mob, muaj cannabinoid nyob hauv cov kua tshuaj.

Nyob ntawm seb hom kev kuaj twg, ntshav, tso zis (tso zis zis) lossis qaub ncaug (sib npaug rau rub lub paj rwb swab) coj mus kuaj.

Kev tshuaj xyuas yog ua los ntawm cov kws paub txog kev noj qab haus huv.

Raws li phau ntawv qhia, qhov kev xeem raug txiav txim siab tsis zoo yog tias:

• cov zis concentration <25 txog 50 ng / mL
• ntshav qib <0,5 txog 5 ng / mL (kuaj ntshav kuj ntsuas 11OH-THC thiab THC-COOH).
• qaub ncaug concentration <15 ng / mL (kev txhais lus nyuaj ntawm 0,5 thiab 14,99 ng / mL)
