The most efficient and effective route of administration of marijuana is:

• A. injecting it in an oil-based infusion
• B. smoking it
• C. eating it in a brownie
• D. drinking it brewed as a tea

Answer: (B)

The main idea here is how quickly and reliably a drug reaches the brain when it’s taken by different routes. Inhalation through the lungs delivers cannabinoids rapidly into the bloodstream because the lungs have a large surface area and rich blood supply. THC is also highly lipophilic, so once it hits the blood it moves quickly into brain tissue. This combination gives a fast onset of effects, a noticeable peak, and a dose that can be easily titrated by taking additional inhalations. That speed and controllability make smoking the most efficient and effective of the options listed. Edible forms like a brownie go through the digestive system and the liver, where THC is converted to a metabolite (11-hydroxy-THC) that can be quite potent, but the onset is much slower (tens of minutes to hours) and effects are more variable and longer lasting. Tea is similar in concept to edibles but even less efficient because THC is not water-soluble, leading to slower and less predictable absorption. Injecting an oil-based infusion could deliver THC very quickly, but it’s impractical and unsafe in typical use due to formulation issues and risks, so it isn’t a practical or reliable route. So, the rapid, high-bioavailability delivery to the brain via smoking makes it the most efficient and effective option among those presented.
