Admit it: you did the drugs, you raved all night at Burning Man, and the whole experience was otherworldly. But now you're heading back to work wondering how long those traces of those drugs will remain in your system. It's important to plan ahead for these kinds of things, particularly since failing a drug test can mean the difference between everything from keeping a job to maintaining a place on your sports team to saving a life. There is no clearcut timeline of drugs making their way through a person's liver and kidneys before being flushed out of a person's body via sweat, urine, or defecation: the best idea for passing a drug test is to avoid illegal substances in the first place.
But if you've gone ahead and done the drugs, you will want to know how your body processes them. The way your body works through hard substances, that all depends on the type of drug, the level of use, the health of the kidneys and liver of the user and their fitness level. The type of drug test being administered and what bodily fluids are used for detection determines the timeframe for testing positive for drug use. The worst drugs for you to ingest can be found in blood, urine, saliva, and even hair for days or weeks after use. But each drug is different, and looking at the whys and hows is fascinating — and may lead to more cautious use in the future.
Cannabis is most commonly smoked, though some people ingest it via oils or by integrating it into baked goods and teas. The drug enters the blood stream through the lungs or digestive system, spreading cannabinoids including THC into the brain and other organs in the body. The resulting is that euphoric, relaxed feeling AKA "a high." Cannabis metabolizes via water, thus moving through and leaving the body fairly quickly through urine; the process takes longer if you take an edible versus if you smoke it.
Delta-9 THC, on the other hand, is a psychoactive kind of TCH which gets caught on your saliva glands inside your mouth. It doesn't really enter the bloodstream — it's chemical makeup doesn't allow for that — and so it stays in your mouth until you take care of it. Eating fatty foods which act as magnets for THC or brushing your teeth can help expedite the process.
Cannabis can be detected in urine for two to seven days after use, and sometimes even 30 days after use. In the blood you're probably safe after two weeks, and it can hang around in your hair follicles for as long as 90 days — longer than in any other part of your body. The weirdest part is that you can also test for cannabis use from years previous — that's how long the traces remain. Certain detox cleanses can help flush your system with a tight turnaround, though, and regular marijuana use traces are of course harder to eliminate than more sporadic usage.

Heroin can be smoked, snorted, inserted as a suppository, ingested, or injected. Injection is the quickest way to get the drug into the bloodstream, with a suppository being the next fastest route. Users experience euphoria, become less anxious, and feel warmer. Heroin is highly addictive, and the effects are typically longer-lasting than other drugs including cocaine and methamphetamines. According to American Addiction Centers, a nonprofit organization for recovering drug addicts,
[Heroin] has a particularly short half-life of only 30 minutes. This means that if a user takes a single dose of heroin, it will take 30 minutes for half of the drug in the person’s system to be flushed out. Some studies suggest that this half-life is as short as 3-8 minutes.
After the high, the body begins to metabolize the drug and its effects dissipate within hours. Drug tests can detect heroin in the bloodstream for 12 hours after ingestion, in saliva for 24-36 hours, three to four days via urinalysis, and up to three months in hair follicles.see more on Heroin
Lysergic acid diethylamide is commonly known as LSD or acid. It is a hallucinogen synthesized from a fungus that is usually ingested in a pill form or by placing paper that has soaked in LSD into the mouth. Once ingested, the user will feel the effects within 30-90 minutes; a "trip" consists of delusions, hallucinations, mood swings, and impaired perception.
Blood can be tested for up to five hours after ingestion of LSD and detect the drug. Urine and hair tested within three days of ingestion may also test positive.see more on Lysergic acid diethylamide
Cocaine is a stimulant that is commonly snorted, though it may also be dissolved in water and injected directly into the bloodstream. Crack cocaine combines powdered cocaine with water and sodium bicarbonate — typically baking soda — and may be smoked.
Snorting the drug allows it to enter the bloodstream via mucus membranes in the nose and give the user a boost of energy for up to half an hour. Injecting or smoking the substance brings on the high more quickly, but it doesn't last as long — the average high lasts 10 minutes.
After using cocaine it can be detected in a blood test for up to two days; in urine for for as many as 4 days; in hair follicles for nearly three months.see more on Cocaine
