The time that drugs remain within your system is based on various variables. The frequency and quantity of your use of drugs, along with your body weight and other medical issues, influence the time that a substance remains within your bloodstream. Certain substances can remain in your system longer than other drugs, like MDMA (ecstasy) and hydrocodone. These substances can stay within your body for several weeks or more if you are addicted to them frequently. The time that the drug stays in your system depends on the way it is processed through your system. The drugs that are metabolized more quickly, like benzodiazepines and methadone, remain in your body for a shorter time than drugs that are slow to be metabolized, such as Cocaine. Furthermore, the half-life duration of a substance can influence how long it takes to be cleared completely from the body. Every drug has its half-life, determined by the equilibrium between your body’s metabolism and excretion rates. For instance, the half-life for marijuana could be as short as one hour or up to 4 days, based on the amount you consume. It is crucial to be aware that if you are using cannabis for smoking or it in any way, such as edible marijuana, the metabolites produced will be detected during a drug test. Many have attempted to pass drug tests. However, it is impossible to pinpoint precisely when a substance is out of your system. This is particularly true if you’ve stopped using the substance but are still a test. It could take a few days or several weeks before the next test.
