How long does cocaine stay in your system?

If you've taken cocaine, this is how long it might stay in your blood, urine, saliva and more.Written by: Rachael HeadesSenior mental health & addictions writer

Taking cocaine causes an intense but brief high and people who take a lot of cocaine tend to do so in order to continue feeling the short-lived effects.

As you take more cocaine, tolerance grows, meaning that you need to take more and more cocaine to feel the high.

In this blog, we explore how long cocaine stays in your system. We'll also provide information on the symptoms of cocaine addiction and the cocaine addiction rehab we can provide at Priory.

How long does cocaine stay in your body?

After your last use, cocaine can remain detectable in your system for weeks. It will remain detectable to tests in your blood and salvia for up to 2 days (48 hours), urine for up to 4 days (96 hours), and hair follicles for up to 90 days.

These figures may vary depending on how much you've consumed and how regular your use of the drug is.

When you take cocaine, your body quickly begins to break it down into substances called metabolites. Metabolites remain in your system for a while, and can be detected by tests that are used to find cocaine in your system.

There are many methods of detecting cocaine in your system. The most commonly used test is a urine sample because it's non-invasive, meaning nothing has to go into your skin.

Depending on the reason for your test and who is performing the test, blood samples or swabs might be used.

How long does cocaine stay in your blood? 

Cocaine can be detected in your blood up to 2 days after taking it.

How long does cocaine stay in your saliva?

What affects the detection time?

Detection time, also referred to as a detection window, is the timeframe within cocaine can be found in your body via a test.

While the above gives some indication as to how long it’s possible for cocaine to stay in your system, this can vary depending on a number of different factors, including:

• How much cocaine you've taken – the more cocaine you've taken, the longer this can stay in your system
• How frequently you take cocaine – the more frequently you take cocaine, the longer it can stay in your system
• The method that you've used to take cocaine – cocaine that's snorted or dabbed onto your gums may stay in your system for longer than cocaine that's been smoked or injected
• Whether you've drunk alcohol at the same time as taking cocaine – if you've been drinking alcohol at the same time as taking cocaine, this can result in the cocaine staying in your system for longer
• Your weight and metabolism – the higher your levels of body fat, the longer the cocaine can stay in your system

How long do the effects of cocaine last?

Typically, a cocaine high will only last 20 to 30 minutes, which encourages people to take more cocaine, but the side effects can last for a little while longer.

Short-term effects of cocaine use can include:

• Risky behaviours due to being overly confident
• Agitation and restlessness
• Physical symptoms, such as a high body temperature, sickness, high blood pressure, increased heart rate, sweating, breathing problems and stroke

Long-term effects of cocaine use can include:

• Anxiety and panic attacks
• Insomnia
• Psychosis
• Paranoia
• Intense mood swings
• Feeling as though cocaine has taken over your life
• Finding that you’re unable to stop taking cocaine, despite wanting to

After taking cocaine, you may also experience what's known as a cocaine comedown/crash the next day. Depending on how much cocaine is in your body, the symptoms of a comedown can vary, but the most common symptom is excessive fatigue. You may also experience psychological symptoms, such as depression and anxiety, and physical symptoms, like a stomach ache.
