cocaine effects, cocaine psychological and physical effects.

The immediate cocaine effect

Immediate euphoria, a feeling of invincibility, intellectual and physical power and numbness to pain and exhaustion. The intense high lasts 10-15 minutes, and remaining effects dissapear within an hour. The user may repeat doses to maintain high.

Short term effects

anxiety, hallucinations, feelings of persecutions, bugs under skin followed by tiredness, hunger, depression.

Cocaine also has an inhibitor effect, and coupled with the invincibility effect, it can lead to commit violent acts or sexual agressions.

Crack effect and risks

The effect of crack is more intense than cocaine as it reaches the brain quicker but the effect is more brief in time.

Crack can: quickly damage the brain, the lungs, stop the respirotory system, heart attacks leading to death.

Cocaine Tightens Blood Vessels

Cocaine causes the body's blood vessels to become narrow, constricting the flow of blood. This is a problem. It forces the heart to work harder to pump blood through the body. (If you've ever tried squeezing into a tight pair of pants, then you know how hard it is for the heart to pump blood through narrowed blood vessels.)

When the heart works harder, it beats faster. It may work so hard that it temporarily loses its natural rhythm. This is called fibrillation, and it can be very dangerous because it stops the flow of blood through the body.

Many of cocaine's effects on the heart are actually caused by cocaine's impact on the brain -- the body's control center..
