Nellie from Drugslab tries Cocaine

Cocaine increases levels of the natural chemical messenger dopamine in brain circuits controlling pleasure and movement.

Normally, the brain releases dopamine in these circuits in response to potential rewards, like the smell of good food. It then recycles back into the cell that released it, shutting off the signal between nerve cells. Cocaine prevents dopamine from recycling, causing excessive amounts to build up between nerve cells. This flood of dopamine ultimately disrupts normal brain communication and causes cocaine’s high.

Short-term health effects of cocaine include:

  • extreme happiness and energy
  • mental alertness
  • hypersensitivity to sight, sound, and touch
  • irritability
  • paranoiaextreme and unreasonable distrust of others

Some people find that cocaine helps them perform simple physical and mental tasks more quickly, although others experience the opposite effect. Large amounts of cocaine can lead to bizarre, unpredictable, and violent behavior.

Cocaine’s effects appear almost immediately and disappear within a few minutes to an hour. How long the effects last and how intense they are depend on the method of use. Injecting or smoking cocaine produces a quicker and stronger but shorter-lasting high than snorting. The high from snorting cocaine may last 15 to 30 minutes. The high from smoking may last 5 to 10 minutes.
