What happens immediately after a person takes methamphetamine?
The drug alters mood in different ways, depending on how it is taken. Immediately after smoking or intravenous injection, the user experiences an intense “rush” or “flash” that lasts only a few minutes and is described as extremely pleasurable. Smoking or injecting produces effects fastest, within five to ten seconds. Snorting or ingesting orally produces euphoria – a high but not an intense rush. Snorting produces effects within three to five minutes, and ingesting orally produces effects within 15 to 20 minutes.
