Typically, drugs that are smoked or injected will leave the body faster than those that are snorted. Drugs that are swallowed will stay in the body longest.
Typically, it will take longer for your body to metabolize a drug that is swallowed in pill or tablet form. Drugs taken in this way need to be broken down through the gastrointestinal system. They can take longer to get into the bloodstream and therefore longer to get out.
The more you use a drug, the more tolerant your body becomes to lower doses. This can cause you to increase your dosage. If you are a regular drug user, it will also take longer for the drug to leave the body. Even if it doesn’t feel like it is still active in the bloodstream, it can still be detected through a drug test.
Detox is when drugs process out of the body. When drug dependence is significant, withdrawal symptoms can be painful and even potentially life-threatening. It can take some time for your brain to stabilize after using drugs, especially when drug dependence is a factor.
If you are highly active, have a low body-fat index and high muscle mass, and exercise regularly, you will likely process drugs through your system faster than a heavier and more sedentary person.
