Unfortunately, there is no easy answer to “how long will it take to get addicted to meth.” The rate of addiction will depend on personal physiology, frequency and amount of meth use, the purity and potency of meth, among a variety of other determinations.
Generally, meth is one of the easiest drugs to become addicted to. This is due to meth’s effects on the brain. Meth creates an intense but brief “flash” or “rush” that can be connected to dopamine in the brain. Dopamine is the “feel-good” chemical responsible for elevated moods, and meth heightens dopamine to unnatural, euphoric levels. While the stimulant effect may last hours, the initial rush fades quickly, leaving the meth user ready to use again in an effort to regain the initial high.
