Effects Of Cocaine That Contribute To Depression

Cocaine is a stimulant, and it activates the sympathetic nervous system. Cocaine exposure can cause significant changes in neurons that release glutamate.

Glutamate is an amino acid that nerve cells use to send signals to other cells. Cocaine abuse causes long-term changes in dopamine and glutamate systems.

During the withdrawal process, the glutamate levels drop, which research has shown is a factor in depression.

Cocaine produces extreme highs, which turn into extreme lows. When a person abuses cocaine, their brain is not able to properly adapt to the negative consequences of drug use.

Symptoms Of Cocaine Use Linked To Depression

If you or a loved one have abused cocaine, there is a range of symptoms that may lead to or worsen the effects of depression.

Symptoms that may cause depression include:

  • insomnia
  • paranoia
  • loss of appetite
  • financial problems
  • mood swings
  • irritability
  • low sex drive
  • anxiety or panic attacks
  • hallucinations
  • aggressive behavior
  • vivid or unpleasant dreams

How Withdrawal From Cocaine May Lead To Depression

Cocaine has a short half-life, which is the time it takes for half of the drug dose to be cleared from the body. The effects of cocaine occur quickly, especially when smoked.

This also means that the comedown happens relatively soon after the last dose, and withdrawal symptoms follow.

The comedown from cocaine abuse can be intense, sometimes resulting in severe depression, paranoia, or suicidal thoughts.

In order to avoid symptoms of depression from the comedown or withdrawal symptoms, people may continue abusing cocaine, which in turn increases the risk of addiction.

Recovering From Cocaine Abuse And Depression

The onset of depression after cocaine abuse can take a real emotional and physical toll on a person. Depending on the person, these effects can last weeks, months, or years.

A safe way to come off of cocaine is through a supervised detox program or another personalized treatment plan.
