However, the drug can be detected for up to 90 days in other types of drug tests like hair follicle tests. Moreover, these are estimates, there are a number of individual things that can impact how long something like methamphetamine can stay in the body.

These include:

Type of Meth

The type of meth used can affect how long it stays in the body. Methamphetamine hydrochloride (HCl) is the most common form of meth and stays in the body for the shortest amount of time. Freebase and crystal stays in the body for longer periods of time.

Amount of Meth

The more meth that is used, the longer it will take to be eliminated from the body.

Body’s Unique Metabolism

Individuals with faster metabolisms will tend to clear meth from their bodies more quickly than people with slower metabolisms.

Age of Person

Current Health Condition

Individuals with health problems, such as liver or kidney disease, may have a harder time clearing meth from their bodies.

Other Drugs Used

Crystal Meth

Crystal meth has a similar detection time as general methamphetamine. If you are trying to learn how long does crystal meth stay in your system, 4 days is a good estimate for a urine test with longer detection times for hair follicle tests.

Half-Life

The half-life of a drug is the time it takes for half of the drug to be eliminated from the body. The half-life of methamphetamine is about 10 hours. This means that if you take 100 milligrams of methamphetamine, after 10 hours, there will be 50 milligrams of methamphetamine left in your body. After another 10 hours, there will be 25 milligrams of methamphetamine left, and so on.

The half-life of a drug is important because it can help to determine how long the drug will stay in your system and how long it will take for the drug to have its effects.
