A man is ready to do cocaine at a music festival

Despite the well-known dangers that cocaine use presents, it remains the second most commonly abused drug in the world behind only marijuana. (1)

Here we take a look at the signs a loved one may have an issue with cocaine by reviewing the effects of cocaine use, along with the amount of time cocaine remains in the user’s system.

Signs of cocaine use

What is the duration of cocaine’s effect?

The duration of cocaine’s effect on the user (how long the high lasts) varies on the route of administration. When taken orally, the duration of cocaine’s effect on the user is approximately an hour long.

When cocaine is snorted, the effects last typically around half an hour. When cocaine or crack is smoked or freebased, the duration of effect is much shorter, usually lasting about ten minutes. Injecting cocaine provides the user with the shortest (but strongest) duration of effect, only lasting about five minutes.

How long does Cocaine stay in the system?

Cocaine has a half-life of approximately one hour. In other words, the amount of cocaine in the users body decreases by one half approximately every hour. Cocaine use can typically be detected by urine drug tests for approximately two to four days after the last use of the drug. This number, however, increases if the user is a chronic user with long binge periods. (2)
