💡TL;DR: Yes. Smoking weed can damage your lungs. Cannabis smoke carries many of the same toxins as tobacco and irritates airways, causing cough, phlegm, and bronchitis; these symptoms often improve after quitting (CDC, American Lung Association). Tobacco causes far more proven long-term disease because people smoke it more often,

💡TL;DR: Airway inflammation means your breathing tubes are swollen and narrowed, often making extra mucus that causes cough, wheeze, and chest tightness. Most acute cases follow viral bronchitis, while chronic inflammation shows up in asthma and COPD; in asthma, 50–70% of patients have Type 2 (allergic) inflammation. The

💡TL;DR: Asthmatic bronchitis is a short-term chest infection on top of asthma, so you get the cough and mucus of bronchitis plus the wheeze and tight chest of an asthma flare. Most cases are viral and antibiotics are usually not needed. Expect about 2–3 weeks of symptoms, with

💡TL;DR: 70% SpO₂ is a medical emergency. Normal is 95–100% at sea level; anything below 80% is severe and can injure organs fast. At 70% you usually have minutes to a few hours without urgent treatment—call 911. Chronic lung disease does not make 70% “normal”; long‑term

💡TL;DR: Ipratropium bromide plus albuterol sulfate opens tight airways quickly for COPD and severe asthma flares. Most side effects are mild and short-lived (shaky hands, dry mouth, brief fast heartbeat), while serious symptoms are uncommon; seek care immediately for chest pain, swelling, or worse breathing right after a dose

💡TL;DR: Empyema = around the lung; lung abscess = inside the lung. Empyema usually needs drainage plus antibiotics; a lung abscess usually responds to antibiotics alone. CT is the best way to tell them apart; a classic study found CT correctly distinguished them in every case. Empyema carries higher short-term risk

💡TL;DR: Valley Fever can leave a small lung nodule (a scar) in about 5% of infections, and most are harmless and do not become cancer. In endemic areas, many nodules that look suspicious on scans prove to be Valley Fever scars; doctors balance watchful follow-up vs biopsy based on

💡TL;DR: Empyema is an infected pleural effusion (pus in the pleural space) that usually needs urgent drainage plus IV antibiotics, while a typical pleural effusion is extra fluid that is often not infected and is treated by fixing the cause and draining only if needed. Doctors look for loculations

💡TL;DR: A nebulizer can help COVID-related wheeze or chest tightness, especially if you have asthma or COPD, but it does not treat the virus. If you already have a prescription, keep using it as directed; if you do not, talk to your doctor before starting any nebulized medicine. Use
