Without any regard to the mode of consumption, the effects are same on the system. Continuous cocaine usage also damages liver, lungs, intestines, and heart.
Cocaine is responsible for excitement, and a feeling of strength and euphoria. This is because the drug interferes with the pleasure centers of the brain where chemicals such as dopamine are produced. The drug blocks re-uptake of neurotransmitters such as dopamine, serotonin and norepinephrine. As a result they stay in the space between nerve cells for a longer time. Hence a feeling of well-being, alertness and self-confidence is enhanced in the user. Euphoric effects last for about 15-30 minutes in a person. Cocaine is also an appetite suppressant decreasing hunger. The drug also affects peripheral nervous system. Because of this, the effects like increase in body temperature, blood pressure and heart rate are observed.
Long-term effects of cocaine are associated with the damages of central nervous system. This increases the chances of heart attack, stroke, and convulsions. It may also lead to brain seizures, respiratory failure and finally death. Certain neurological and behavioral problems arise by the use of various doses of cocaine. These include dizziness, anxiety, headache, insomnia, depression, and hallucinations.
