The effects of cocaine

By Kathryn Senior on 20 July 2022

Cocaine has been used in Europe since the mid 19th century when Italian doctor Paolo Mantegazza recommended that patients could use the effects of cocaine to treat a furred tongue in the morning, flatulence and for whitening the teeth. Coca leaves were also used in the original recipe for Coca-Cola for the first 20 years.

The immediate effects of cocaine


The effects of cocaine are almost immediate and will last for between fifteen and thirty minutes, depending on how the drug is taken. The main effect of cocaine is a feeling of stimulation, with emotional symptoms including:

Alertness
Heightened confidence
Euphoria
Sexual arousal
A more social / talkative mood
This feeling of invincibility can lead to cocaine users taking dangerous risks or getting involved in situations that they would normally avoid, such as crime or unprotected sex.

The physical effects of cocaine include:

Increased heart rate
Increased blood pressure
Dilated pupils
Increased body temperature
The immediate effects of cocaine wear off completely very quickly, creating a drop in mood and energy levels. This often triggers people to want more of the drug to recreate the ‘good feeling’ they have just experienced.

Explaining the effects


The euphoric effects of cocaine are felt because the drug fools the body into thinking it has experienced a pleasurable sensation. Cocaine stimulates the brain to release the pleasure chemical dopamine and then blocks the natural re-absorption of this chemical to prolong the high. Eventually, the brain overcomes the effects of cocaine and re-absorbs the dopamine rapidly, causing the sudden drop in mood.

The addictive effects


The effects of cocaine can feel so pleasurable that many people become regular users as they strive to return to that pleasurable state. This can result in cocaine binges, where users take more of the drug each time the effects wear off, and can also lead to regular usage or addiction.

What’s more, as the body becomes more and more resistant to the drug, the amount of cocaine required to produce the desired effect increases, leading to a greater and greater need. With cocaine costing between £30 and £50 an ounce, the habit soon becomes expensive, and the effects of cocaine quickly spread beyond the physical to economic, emotional and social issues.

The long term effects


Regular use of cocaine can create a range of problems, as the effects of cocaine cause serious damage throughout the body. The act of taking the drug itself can cause damage:

Injecting cocaine can cause infections, such as HIV and Hepatitis, from shared needles and damage to the veins (since the drug is also a local anaesthetic this damage often goes unnoticed at the time)
Smoking cocaine as crack can cause lung damage, breathing problems and even cancer
Snorting cocaine, perhaps the most infamous method of all, can cause damage or complete disintegration of the septum in the middle of the nose.
There are also many side effects of cocaine that only appear with long term use. These include:

Anxiety, paranoia and panic attacks
Depression and a lack-lustre, run down feeling
Aggravation of underlying mental health problems
Miscarriage, premature birth and low birth weight babies

The dangerous effects


Cocaine is highly addictive, and this in itself can have some very dangerous effects, as discussed above. However, cocaine is rarely used on its own, and this is where many of the biggest dangers lie. The effects of cocaine, when mixed with alcohol, can be highly toxic, and when mixed with other drugs, can be fatal.

The biggest danger for cocaine users is that of overdose, as increasingly large doses are needed to recreate the high. An overdose occurs when the effects of cocaine on the heart and respiration become too much for the body to take. This can result in:

Heart attack or heart failure
Brain haemorrhage or stroke due to high blood pressure
Convulsions leading to respiratory failure

Are the effects worth the high?


There is no denying that the effects of cocaine make you ‘feel good’ while they last, and the immediate damage is no greater than the damage from cigarettes or alcohol. However, the highly addictive nature of the drug means that the short-term effects of cocaine are far outweighed by the dangers.
