The common cold, a frequent viral infection, often prompts individuals to seek various remedies. Many wonder if cannabis can offer a cure. While cannabis has gained attention for its potential therapeutic properties, it does not cure the common cold or eliminate the viruses responsible for the infection.
Cannabis and Viral Immunity
Common colds are caused by viruses like rhinoviruses, which infect the upper respiratory tract. The body’s immune system naturally fights these viral invaders. There is no scientific evidence that cannabis, or its cannabinoids like THC and CBD, can eradicate the cold virus or cure the infection. While some preclinical studies have explored the antiviral potential of cannabinoids and terpenes against other viruses like SARS-CoV-2, HIV, or hepatitis C in laboratory settings, these findings do not directly apply to common cold viruses or translate into a cure for human infections. The anti-inflammatory properties observed with certain cannabinoids do not equate to an antiviral action that resolves a viral infection.
Managing Cold Symptoms with Cannabis
Despite not offering a cure, cannabis may provide some relief for certain cold symptoms. Cannabinoids like THC and CBD may alleviate cold discomfort. For instance, cannabis may reduce body aches and headaches due to its pain-relieving effects.
THC can also alleviate nausea and stimulate appetite, beneficial when illness reduces the desire to eat. Additionally, sedative effects of some cannabis strains, especially those high in THC, might improve sleep quality, crucial for recovery.
Any relief is symptomatic, addressing discomfort rather than the underlying viral infection. Individual responses to cannabis can vary.
Considerations for Cannabis Use During Illness
Using cannabis, especially through inhalation, during a cold presents several considerations. Smoking cannabis can irritate the throat and airways, potentially worsening coughs, increasing phlegm production, and exacerbating a sore throat. Vaping cannabis, though perceived as safer, can also cause respiratory irritation, lung inflammation, and damage, undesirable when the respiratory system is already compromised. Cannabis can also interact with over-the-counter cold medications, especially those with sedative effects like antihistamines or cough suppressants, intensifying drowsiness and potentially impairing judgment. Some cannabinoids may also influence liver enzymes that process other medications, potentially altering their effects.
Proven Approaches for Cold Relief
Since there is no cure for the common cold, effective management focuses on alleviating symptoms and supporting the body’s natural healing process. Rest is important, allowing the body to conserve energy and fight the infection.
Staying well-hydrated by drinking fluids like water, clear broths, or warm lemon water with honey can prevent dehydration and loosen congestion. Gargling with salt water can provide temporary relief for a sore throat. Using a humidifier adds moisture to the air, easing stuffiness and soothing irritated airways. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can reduce body aches and fever.
