Misuse can be test for easily. Meth shows positive in blood between 1-3 days, a further 2 days in urine, and can be traced in hair follicles for up to 90 days. Habitual or chronic use can mean blood and urine detection for almost the same length of time as the hair follicle detection.
The drug itself exits your body that quickly, but the after-effects don’t disappear. Drug tests search for the metabolite that the body produces post-ingestion. Frequent use prolongs the length of time the specific metabolite lasts in the system.
Other symptoms are those physical and mental affects that usage has. Meth is used to improve energy levels and increase alertness, but high doses and a high addiction rate mean it’s very dangerous. The chemical triggers a mass release of dopamine. Addicts find they are more prone to developing psychosis, similar to schizophrenia. They are also vulnerable to anxiety problems, repetitive and obsessive behaviour, paranoia, violent tendencies and subsequent depression and fatigue should you attempt to withdraw. Cognitive deficits are also a common side effect, and include memory loss, impaired attention and poor executive function capacity. This deterioration is associated with Parkinson’s Disease and can develop into it.
Methamphetamine usage has a strong association with suicide, but also with physical cardiovascular damage, which can cause and accelerate heart disease.
