Le THC ou tetrahydrocannabinol ʻo ia kekahi o nā mole i hana nui o cannabis. ʻO kēia cannabinoid. Kuhi ʻia aia kahi "ami" i 2 a 20 mg o THC a ke hanu ʻia 15-20% o ka THC i ka uahi e hele i loko o ke koko.

Hiki iā ia ke ʻike ʻia i ka lihi, mimi, lauoho, lauoho o ke kino, a pēlā aku.

Ke hoʻomau nei nā hopena psychotropic o ka cannabis a hiki i 12 mau hola, kaukaʻi ʻia i ka ʻai a me ka noʻonoʻo o ke kumuhana.

ʻO ka puka aniani o ka hika o THC no laila pili i ka makahiki, ka nui a me ka maʻamau o ka ʻai ʻana.

E hoʻomaopopo i hoʻokahi manawa i ke kino, ua haki ʻo THC i ʻelua mau hui, 11OH-THC a me THC-COOH. Kuhi ʻia ʻo THC i loko o ke koko i kekona kekona ma hope o ka inhalation mua, hiki ke piʻi kiʻekiʻe o 11OH-THC ma kahi o 30 mau minuke a me ka nui o THC-COOH ma lalo o 2 mau hola.

Ma hope o ka hoʻohana cannabis, ma ka inhalation, ʻike koke ʻia ʻo THC i ke koko. ʻIke ʻia kona alo i ka mimi a me ka lawai. Hoʻohana ʻia ʻo THC ma ke ʻano he marker e ʻike ai i ka ʻai cannabis, pinepine i loko o ka pōʻaiapili medico-kānāwai (ulia alanui, kānalua i ka hoʻohana lāʻau, a me nā mea ʻē aʻe) a i ʻole ka ʻoihana (lāʻau lapaʻau ʻoihana).

Hoʻohana ʻia kekahi mau hoʻokolohua, kaukaʻi ʻia i ka pōʻaiapili.

• loiloi koko : hiki iā ia ke ʻike i ka ʻai ʻana o ka cannabis ma waena o 2 a 10 mau hola ma hope o ka lawe ʻia ʻana (ʻimi ʻia ʻo THC, 11OH-THC a me THC-COOH). ʻOi aku ka makemake o kēia hōʻike i ka hanana o kahi ulia ala, no ka laʻana. Hoʻohana ʻia ia e kuhi i ka manawa i hala ma waena o ka hopena hope loa a me ka hoʻāʻo ʻana o ke koko. Ke kiʻekiʻe ka noʻonoʻo o THC ma mua o 11OH-THC, hōʻike ia i ka lawe ʻia e ka inhalation. ʻO ka hope he hōʻike o ka ʻai ʻana e kaʻai ʻana. Ma hope o 3 a 4 mau lā, hoʻopau loa ʻia nā cannabinoids mai ke koko.
• kānana mimi (THC-COOH): hiki iā ia ke hoʻomaopopo i ka lawe manawa ʻana a hiki i 2 a 7 mau lā ma hope, a ʻoi aku ka lōʻihi i ka hanana o ka ʻai mau (7 a 21 mau lā, a ʻoi aku paha).
• kānana lawaiʻa (THC): hoʻohana ʻia i kekahi manawa e nā keʻena mālama kānāwai e nānā i nā kaʻa kaʻa. Hiki iā ia ke huai i ka ʻai mai ka 2 a 10 mau hola. Eia nō naʻe, ʻaʻohe ʻae i kona hilinaʻi ʻepekema (ke ola o nā hopena wahaheʻe).

I ka lauoho (maʻamau i ka hanana o kahi autopsy), hiki ke ʻike ʻia ka ʻai ʻana i mau mahina a i ʻole mau makahiki ma hope (ulu ka lauoho i ka awelika o hoʻokahi knm / mahina a ʻaʻole e nalo nā koina THC).

ʻO kēlā me kēia hōʻaʻo e hana ʻia (ke koko, mimi a i ʻole lawehala), pili ia i ka ʻimi ʻana, mahalo i ka hoʻohana ʻana o nā anti-THC antivities, ke kū ʻana o ka cannabinoid i ka wai i hoʻāʻo ʻia.

Kaukaʻi ʻia i ke ʻano o ka hoʻokolohua i hana ʻia, e lawe ʻia kahi laʻana, ke kō, mimi (hōʻiliʻili mimi) a i ʻole salivary (e like me ka ʻānai ʻana i ka pulupulu).

Lawe ʻia nā anamanaʻo e nā loea forensic.

Ma ke ʻano he alakaʻi, manaʻo ʻia he maikaʻi ʻole ka hoʻāʻo inā:

• ka nui o ka mimi <25 a 50 ng / mL
• ke kiʻekiʻe o ke koko <0,5 a 5 ng / mL (ʻo ka hoʻāʻo ʻana o ke koko e helu pū i ka 11OH-THC a me THC-COOH).
• ʻO ka paʻa ʻana o ka saliva <15 ng / mL (nā paʻakikī o ka wehewehe ʻana ma waena o 0,5 a me 14,99 ng / mL)
