Nasal Congestion Caused by Addiction
Nasal congestion is annoying, but it’s not usually a big deal when it’s just a cold symptom or an allergy flare-up. However, if you’re experiencing constant nasal congestion that doesn’t have a clear cause, it is time to ask yourself whether addiction is behind it. Constant nasal congestion is often an overlooked sign of substance abuse, but if left unchecked, the occasional stuffy nose can escalate into long-term damage. Whether you’re still using, already in recovery or just concerned about someone you love, understanding what causes nasal congestion can help treat both the symptom and its causes.
What is nasal congestion?
Nasal congestion is what most of us call a “stuffy nose.” It happens when the blood vessels and tissues inside your nose become inflamed, swollen or blocked with mucus. You might feel pressure in your sinuses, find it hard to breathe through your nose or constantly be sniffing just to get some relief. A mild case is annoying but when nasal congestion drags on or keeps coming back, it can affect your sleep, mood and even your taste buds.
While congestion is often linked to things like colds or hay fever, it can also point to more serious issues, especially when drugs or alcohol are involved. Nasal congestion from substance use often starts slowly but with repeated use, the tissues in your nose can become chronically inflamed or even damaged.
Substances that are snorted are particularly dangerous as they can cause repeated trauma to the nasal passages. This leads to ongoing swelling, broken blood vessels and a thickening of the lining inside your nose. Even smoking or vaping some drugs can inflame the nasal and sinus areas, and this can eventually lead to constant nasal congestion and more serious complications.
How can addiction cause nasal congestion?
Many people wonder what causes nasal congestion that won’t go away without considering that drug or alcohol addiction may be the instigator. Various substances, including stimulants, heroin and even heavy drinking, affect your sinuses in different ways, but they can all leave you with constant nasal congestion and other debilitating symptoms.
Cocaine is one of the most common culprits. When cocaine is snorted, it causes the blood vessels in your nasal passages to constrict, with the constant irritation leading to inflammation, blocked airways and a chronic stuffy nose. Snorting meth, heroin or crushed prescription drugs can have the same effects as well as persistent nosebleeds, swelling and irritation. In very severe cases, nasal congestion can be an early symptom of more serious conditions (see below).
Even drugs that aren’t used through the nose can cause congestion. Alcohol use can lead to dehydration and inflammation that affects your sinuses, especially if you’re drinking heavily or withdrawing. Cannabis, particularly when smoked, can also dry out the nose and cause swelling in the nasal passages.
What are common symptoms of nasal congestion to look out for?
When alcohol or drug addiction leads to nasal congestion, the symptoms can be uncomfortable, relentless and confusing. Here’s what to look out for if you think your nose might be affected by addiction:
Can nasal congestion become dangerous if left unaddressed?
Prolonged nasal congestion can be very dangerous if it is left unaddressed because it is often a precursor to more serious conditions. These include:
- A deviated septum
- A perforated septum
- Non-allergic rhinitis
- Facial deformity due to a breakdown of the nasal sidewalls
People with non-allergic rhinitis may develop complications such as sinusitis, sleep apnoea, asthma, the inability to smell and recurring infections.
A deviated septum occurs when the bridge (septum) that separates your nostrils becomes misaligned, causing one nostril to become wider than the other. This causes issues, including:
- Difficulty breathing
- Dry nasal passages
- Nosebleeds
- Recurrent sinus infections
- Headaches
- Sleeping difficulties
When a hole develops in the bridge, the condition has advanced to a perforated septum, which creates a whistling sound as air passes through the perforation. When nasal issues develop into a deviated or perforated septum, surgery is necessary to correct the damage.
If a deviated or perforated septum is left untreated, you may lose your ability to smell, or suffer from severe breathing problems which can range in severity from merely annoying to life-threatening.
When should you seek professional treatment for constant nasal congestion?
Constant nasal congestion, particularly if it is linked to substance use, always requires medical assessment to understand the causes and prevent complications. This is a part of every quality rehab treatment because not understanding and treating the underlying causes of your addiction will eventually cause a relapse and a recurrence of nasal issues.
If nasal issues have already caused serious damage, medication or surgery can help repair some of the harm. However, this will only have a limited effect, and if you go back to using drugs or alcohol, more conditions will certainly arise.
