Quizplus · Accepted Answer

Oral ingestion takes the longest time to take effect because the substance must first be absorbed through the gastrointestinal tract and then travel to the liver before entering the bloodstream. This process can take anywhere from 30 minutes to an hour or more, depending on the substance and individual factors like metabolism and digestive health. In contrast, inhalation, injection, and snorting all bypass the digestive system and deliver the substance directly to the bloodstream or brain, resulting in a more immediate onset of effects.
