A recent study has shown that vaporizing cannabis delivers more THC to the bloodstream than smoking, according to Live Science.
In the study, which was conducted by the Substance Abuse and Mental Health Services Administration and John Hopkins School of Medicine , 17 subjects were collected for six separate 8.5-hour sessions, separated by a week or more. Alle deltagere havde ikke ryktet eller indtaget cannabis i den måned før undersøgelsen blev gennemført og blev testet for overholdelse og andre forstyrrelser før undersøgelserne.
De deltagere blev bedt om enten at ryge med et rør eller vaporisere ved anvendelse af en volcano målt doser eller cannabis containing a total of 0mg, 1
0mg or 25mg of THC over the course of the six sessions.
Subjects who vaporized weed had significantly higher amounts of THC in their blood compared to those who smoked an equal dose. Results from the impairment questionnaire also showed increased effects, as those who vaporized not only self-reported more side effects like dry eyes or mouth but also made twice as many failures on cognitive tests.
Researchers theorize that the difference is likely due to losses of THC due to the combustion as well as sidestream smoke, or smoke that is created but not inhaled.
The study also found a disconnect between blood concentrations of THC and subjective drug effects and impairment. Onderzoekers zagen weinig of geen correlatie tussen bloedinhoud en voortdurende effecten. Often, the subjective effects of cannabis intoxication as well as motor skills effects continued well after blood concentrations declined below levels that should show an effect.
Researchers conclude that the amount of THC or other cannabinoids should not be the only consideration when attempting to accurately dose cannabis. Regulators and consumers should both be aware that the method of consumption – even between seemingly similar methods like smoking and vaping whole plant cannabis – can make a big difference in how high a user becomes or how much of a given medicinal cannabinoid enters their body. 19659008]
