Breaking down cocaine
Cocaine use in New Zealand is not uncommon. Here’s what you need to know about it.
Cocaine is a white crystalline powder, and it’s highly addictive. It’s made from a paste extracted from the leaves of the South American coca plant.
As a strong stimulant that affects the body’s central nervous system, it essentially disables the mechanisms that recycle noradrenalin, serotonin and dopamine released in the brain. This means that the amount of these chemicals temporarily increases. It’s also a local anaesthetic.
Cocaine can be injected, smoked, sniffed, or snorted. While not using cocaine at all is the safest option, snorting is considered less frequently harmful than other methods. It still come with other risks like destruction of membranes, cartilage, and even bone inside the nose and head.
What are the effects?
- Temporary feelings of self-confidence and energy
- Numbness of the throat/tongue/mouth (depending on how it was ingested)
- Increased heart rate
- Intense euphoria
- Low appetite
Once the effects wear off, there are strong cravings to use again and binge. This increases the risk of overdose, heart attack, stroke, organ failure, and seizures through overheating. Prolonged use over a single period can also cause psychosis, especially if more is taken instead of sleeping.
The purity of cocaine is variable, which means that a line from one batch could be the equivalent of five lines from another batch. This increases the risk of overdose with symptoms like an increased heart rate, high body temperature, tremors, seizures, difficulty breathing, passing out, symptoms of heart attack and stroke.
If you think someone is suffering from an overdose, call 111 immediately for an ambulance. St John’s has more helpful information on how to deal with an overdose in their first aid guide.
What are the risks?
Cocaine is highly addictive, leading to a strong psychological dependence. This is because it stimulates those key pleasure centres in the brain, including dopamine which is one of the brain’s reward pathways. That’s the element that helps the brain make connections between an activity and pleasure, ensuring we’ll repeat the behaviour.
Tolerance also 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.
Cocaine often spreads through social networks, with many people trying it for the first time when it’s shared by friends. Remember, if you offer cocaine to others, there’s a risk they will become addicted as a result.
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.
