What are the immediate physical effects of taking cocaine?
As well as the feelings of euphoria, immediate physical effects can also include:
- Constricted blood vessels
- Dilated pupils
- Increased heart rate
- Higher blood pressure
- Temporary feelings of self-confidence and energy
- Numbness of the throat/tongue/mouth (depending on how it was ingested)
- Impulsive behaviour
- Low appetite
The effects can last up to 30 minutes, and when the immediate effects wear off, people often report experiencing a crash. This can include:
- Anxiety and tension
- Mood swings
- Disturbed sleep patterns, exhaustion
Most people report feeling strong cravings to use again and binge. This increases the risk of overdose, heart attack, stroke, organ failure, and seizures through overheating. Make sure you know how to recognise the signs of an overdose, and always call 111 if someone:
- is unconscious;
- stops breathing;
- has a seizure;
- is extremely agitated for longer than 15 minutes;
- has chest pain or breathing difficulties for longer than 5 minutes.
Mixing drugs is always a bad idea, and greatly increases the risks. This is especially true for cocaine and alcohol which, as a sedative, can mask the effects of cocaine and lead to re-dosing, putting greater stress on the body. Mixing cocaine with other stimulants can lead to overdose or death through heart attacks, overheating, seizures, or even serotonin syndrome.
What are long-term health effects of taking cocaine?
Repeated cocaine use can put a lot of stress on your body. Because it effects the pleasure and reward pathways of the brain, it can make it harder to get a sense of enjoyment and pleasure from activities you used to enjoy without cocaine use. Some long term impacts could include:
- Permanent damage to the blood vessels of the heart and brain
- Kidney damage
- Lung damage
- High blood pressure
- Increased risk of heart attack and stroke
- Abdominal pain and nausea
- Insomnia and exhaustion
- Light and sound sensitivity
- Weight loss and eating disorders
- Sexual dysfunction
- Cerebral atrophy and impaired thinking
- Aggressive or violent behaviour
Different ways of consuming cocaine can also lead to different long-term problems – destruction of nose tissue if snorted, infection risk if injected, or respiratory failure if smoked.
Tolerance to cocaine develops quickly, meaning more cocaine is needed to have the same effect while the cravings become more intense. All of this means it’s easy for moderate, social use to become destructive, constant use.
