Overdose Potential

According to the National Institute of Drug Abuse (NIDA), an overdose is brought on by a person that takes enough of the drug to reach toxic levels to their system. Overdose toxicity can largely depend on the individual user and their specific susceptibility to the toxins. Potency of the drug can also vary as it is often mixed or ‘cut’ with other materials.

Due to cocaine being a very powerful stimulant, an overdose can lead to the failure of a number of organ systems and physiologic functions, causing the brain and body to shut down.

Typical signs of an overdose:

  • Dangerously high blood pressure.

  • Irregular heart rate.

  • Extremely high body temperature.

  • Extreme anxiety or confusion.

  • Psychosis.

  • Nausea.

  • Agitation or tremors.

These symptoms may precede the onset of a heart attack, stroke or seizure.


Symptoms depends on several factors including tolerance, length of addiction, metabolism, and severity of addiction. Withdrawal can be a painful and uncomfortable process and is often the reason why a person would rather return to their drug use.


Symptoms may include the following:

  • Difficulty concentrating

  • Slowed thinking

  • Exhaustion

  • Restlessness

  • Anhedonia, or the inability to feel pleasure

  • Depression or anxiety

  • Suicidal thoughts or actions

  • Vivid, unpleasant dreams or nightmares
