All right, so i see that you need help with this question, and it says, concerning the time course of thc levels in route of administration, a, plasma levels of thc peak more rapidly following the injection or smoking than oral administration of the drug.
00:22
B, people smoking marijuana typically reach their peak thc levels before they finish the cigarette or joint.
00:29
C, oral administration of thc produces low plasma levels that drop off quickly.
00:37
D, at maximum thc intoxication after smoking, brain and plasma thc levels are equilibrated.
00:49
So analyzing each one of these will evaluate the accuracy of each statement based on what is known about thc.
01:00
So taking a look at statement a, okay, plasma levels of thc peak more rapidly following injection or smoking than oral administration of the drug.
01:15
This statement is accurate.
01:21
When thc is smoked or injected, it bypasses the digestive digestive system and liver, which metabolizes and slows the absorption of substances, leading to a rapid increase in plasma thc levels.
01:50
In contrast, oral administration, so this is if it's smoked, oral administration involves digestion, and they first pass through the liver, slowing down the absorption into the bloodstream.
02:25
Statement b, people smoking marijuana typically reach peak thc levels before they finish their cigarette or joint.
02:37
This statement is misleading because while smoking does lead to rapid increase of thc levels, the peak levels are usually reached shortly after finishing the cigarette or the joint...
