Effects of Crack Cocaine

Constricted blood vessels, increased body temperature and hyper blood pressure are the main physical effects of crack use. Smoking crack may cause respiratory problems and severe chest pains with lung trauma and bleeding. The human liver has a tendency to combine cocaine and alcohol, if they were used mixed, and to produce cocaethylene, a substance which can increase the risk of sudden death.

Crack works on the automatic nervous system. This system manages the sympathetic system which controls some important functions such as heart beat and breathing. Crack can make the brain's neuro transmitters to release dopamine, a chemical in the brain which releases feelings of happiness.

The long term effects of crack include agitation, mood change, bad temper, auditory hallucinations, and extreme paranoia.

Symptoms of Crack Addiction

Changes in blood pressure and breathing rates, vomiting, anxiety, and insomnia are the most common symptoms of crack abuse. Swelling and bleeding of mucous membranes and damage to nasal cavities are also seen among crack smokers.
