The intensity and length of the symptoms of cocaine withdrawal depend on several different factors, including how long someone has been abusing cocaine, how much of it they were taking, and how they were taking it, to name a few. The cocaine withdrawal timeline is generally broken into three different phases: crash, craving, and extinction. While the previously mentioned factors will have a significant impact on how an individual experiences cocaine withdrawal, it will typically resemble the following process: Cocaine has a very short half-life and peaks very quickly, so someone can begin feeling cocaine withdrawal symptoms as soon as 90 minutes after their last dose. However, it can sometimes take closer to 24 hours for symptoms to manifest. The early symptoms include anxiety, exhaustion, hunger, and depression, and can last as long as several days. This is also generally when the withdrawal symptoms will be at their most uncomfortable. Once the crash stage has run its course, the fatigue, depression, and anxiety will have mostly faded and been replaced with extremely strong cocaine cravings. Symptoms of irritability, restlessness, and difficulty concentrating will be at their peak strength as thoughts of and cravings for cocaine become almost all-consuming. Unlike the crash phase, the craving phase can last anywhere from one week to more than two months. The longer someone has been abusing large amounts of cocaine, the more likely they are to stay in the craving phase, sometimes for as long as 10 weeks. The final stage of cocaine withdrawal is also the longest, sometimes lasting up to six months. At this point, the majority of the cocaine withdrawal symptoms should have either faded or disappeared entirely, although there are still likely to be random, intermittent cravings for cocaine. On the bright side, these cravings will at least be much weaker and less frequent than the cravings experienced in the craving phase.
