The Detection Times of Drugs

Detection time is the period during which a particular drug can be detected. If you’re expecting a possible drug test in the coming days or weeks, it is necessary to know how far back in time a mouth swab test goes. The table below shows drug detection times to make it easier for you to plan ahead and avoid being tested positive.

Drug Detection Time in Saliva
Marijuana (THC) Up to 12-24 hours
Cocaine 1-2 days
Opiates 2-5 days
Amphetamines 3 days
Phencyclidine (PCP) 1-3 days
Methamphetamine up to 3 days
Heroin 1-2 days
Methadone up to 10 days
Morphine 1-2 days
Barbiturates 2-3 days
Ben­zo­di­azepines 3 days
LSD 2 days
Nico­tine Up to 4 days
Alcohol Up to 24 hours

What Does Detection Time Depend On?

Does the table above provide enough information to plan ahead when getting ready for a drug test? Not really! It’s necessary to understand that drug detection times may range dramatically from person to person depending on various factors. For example, the route of administration is very important for determining how far back in time a saliva drug test goes. Therefore, to guarantee success, you need to take into account the following factors:

  • Dosage: how much of a drug you take will either reduce or increase drug detection time.
  • Metabolism: a fast metabolic rate reduces detection time.
  • Body mass: if you’re overweight, you have a slow metabolic rate, and the detection time will be longer. Drugs may also be stored in fat for some time, which makes it possible to detect them for a longer time compared with energetic people who have less fat.
  • Age: older people tend to have longer drug detection times compared with younger people since the rate of metabolism slows down with age.
  • Hydration: increased water intake helps flush out most traces of a drug.
  • Drug tolerance: if you’re tolerant of a certain drug, this can lead to a shorter detection time for this particular drug.

How to Reduce Drug Detection Times in a Mouth Swab Test

You can take certain measures to help clean your system from toxins much faster, thus reducing detection times of drugs, which helps you pass mouth swab test, but you should be careful, as some remedies might not work for you as planned. Remember that everyone is different and reacts differently to certain methods. There is no 100% guarantee, but following the tips below will significantly increase your chances of passing a mouth swab test.

Home remedies

  • Brush your teeth: you should do this at least 3 times a day, paying particular attention to your cheeks, tongue, and gum line.
  • Drink a lot of water: you need to drink a lot of clean water to replace oral fluids and flush out traces of drugs.
  • Chew ice: this will help dilute your saliva and decrease the level of toxins in the test sample.
  • Eat fatty meals: fat helps absorb drug metabolites much faster.
