Which Factors Determine Drug Duration in Your System?
It can be very difficult to determine how long a particular drug will stay in your body, simply because everyone is different and there are numerous variables that determine drug duration in your body. Here are a few things that make a difference:
1. Metabolism
If your metabolism is very fast, that means your body uses up things quickly – including food, water, and any drugs that you put into it. The slower your metabolism, the longer a drug might stay in your system.
2. Hydration and Body Mass
If you are overweight, drugs might linger in your system longer, as they might become trapped in fatty tissue. On the other hand, if you are very thin your metabolism might be high, prompting the drug to leave your system fast. Being very hydrated can help the drugs disappear, but that’s not true every time.
3. Amount and Frequency of Drug Use
How often you use a particular drug can make a big difference. Since a tolerance builds up over time, it stands to reason that the one-time use of a drug might clear your system quickly, but using drugs on a regular basis can lead to a lingering effect in your body. The amount you use makes a difference as well.
4. No Exact Timetable
Researchers have been unable to detect a particular time table on which the drugs leave the system. This is because drugs react differently for everyone; for instance, someone might tolerate pain medication very well and need very little. Someone else might need a higher dose, and that means the drug stays in their system longer, simply because of the sheer volume of it. The bottom line is that there is no exact timetable on when the drug clears the system, so there is no way to know when it is “safe” to test.
List of Common Drugs’ Duration in Your System
Though it can be tough to determine just how long a drug will stay in your body, there are some general rules of thumb when it comes to the most common drugs. Keep in mind that this list is not absolute, and shouldn’t be seen as a certainty.
