Meth, or methamphetamine, is a stimulant that affects the nervous system. It is considered a highly addictive and powerful substance that can cause many complications after long term or even short term use, which is why it is classified as a Schedule II Substance. Due to the potency of methamphetamine, even small amounts of meth can quickly result in either physical or psychological dependence on the drug.
This is because the body begins to absorb meth immediately after the drug is ingested. Once the drug has entered the bloodstream, the user will begin to feel the effects of methamphetamine. These effects can include feelings of euphoria, increased heart rate and blood pressure, elevated body temperature, dilated pupils, increased energy and alertness, and decreased appetite. Long time side effects include paranoia and delusions, skin sores, weight loss, dental issues, sleep disorders, and hallucinations.
The effects of meth can last for a long while, and it may take up to 4 days for the drug to leave your system. The half life of meth is between 9 to 24 hours, meaning this is how long it will take for the body to metabolize half the amount of meth that has been ingested. This time can vary based on individual factors such as metabolism rate, how much meth was ingested, and how often the drug is used.
Many people who take meth often wonder “how long does meth stay in urine,” as a urine test is the most common form of drug test administered. Meth can be detected in urine samples for around 3 to 6 days after the last use, although this can vary if the person is a heavy user.
Other tests to detect meth in the body exist as well, which is why “how long does meth stay in blood” is a commonly asked question. Although blood tests are rarely used since they are more invasive, there are instances where doctors will look at these test results. After using meth, the drug can stay in the system for about 72 hours, although this number can increase to around 10 days for people with a severe meth addiction.
Other types of tests to search for meth in the system include saliva and hair tests. For saliva tests, meth can be detected for 1 to 4 days after the last use, depending on the frequency and amount of meth use. Hair tests can detect meth for the longest period of time out of any test, with test results for meth staying positive for up to 90 days.
While age, frequency and amount of meth use, metabolism rate, liver and kidney function, and the type of test conducted will all factor into how long meth stays in your system, the most important factor is time. This is because the body excretes around 54 percent of meth unchanged from the system, meaning that only 46 percent of the drug contributes to the effects felt upon consumption.
Because of this, not all of the drug has to be metabolized by the body in order for it to exit your system. However, if you are a heavy user of methamphetamine, it will certainly take longer for your body to be rid of the drug. If you are having problems concerning substance abuse and mental health, meth rehab treatment programs such as Arista Recovery can help you end the dependence on methamphetamines.
