If you have used meth recently and need to take a drug test, you might be asking: how can I clear meth from my system quickly? Or more specifically, what’s the fastest way to get meth out of your system without risking your health?

The internet is full of quick-fix claims, but most are ineffective or even dangerous. Methamphetamine can stay in your body for several days, depending on how much you use. There is no sure way to flush it out in 12 hours.

In this guide, we will explain how the body breaks down meth. We will also discuss the factors that affect how long it can be detected. Finally, we will explain why a medically supervised detox is the best option.

How Long Will Meth Stay in Your Blood?

Meth has a half-life of around 10–12 hours, but its metabolites can remain in your system longer. The National Institute of Drug Abuse states that methamphetamine can be found in the blood. This can happen for 1 to 3 days after a person uses it. For heavy or long-term users, it may last even longer.

Detection times for other methods include:

Urine: 1 to 4 days
Saliva: 1–4 days
Hair: Up to 90 days

So, how long will meth stay in your blood depends on your frequency of use, body composition, and overall health.

Fastest Way to Get Meth Out of Your System

We get it — when you want to be clean, you want it fast. But unfortunately, the fastest way to get meth out of your system isn’t a magic drink or a home remedy. Staying hydrated, sleeping well, and eating healthy help your body detox. However, they won’t speed up the process a lot.

Most “flush” products or detox kits simply dilute your urine, and lab tests can easily flag those anomalies.

The safest and most reliable way to remove meth from your system quickly is through medical detox. This is especially true for frequent users.

Why Detox Drinks and Home Remedies Don’t Work

There’s no shortage of advice online about using cranberry juice, niacin, vinegar, or B-vitamins to detox quickly. But there’s zero clinical evidence that these work.

The National Institute on Drug Abuse (NIDA) says that only time and your body can clear meth. At-home methods might briefly mask it, but drug screenings can also flag them.

Detox Speed Depends On…

Everyone’s body processes meth differently. Some of the biggest factors that affect how long meth stays in your blood and body include:

Duration and intensity of use
Method of administration (smoking, snorting, injecting)
Liver and kidney function
Age, body fat, and hydration level
Use of other drugs or medications
