Exacerbation of Asthma: The patient has a history of asthma and is presenting with wheezing on all lung fields and a cough, which are classic symptoms of an asthma exacerbation. The recent vaping could have triggered or worsened the symptoms.

Vaping-Related Lung Injury (EVALI): Given the patient's recent history of vaping, EVALI is a possible diagnosis. Symptoms can include cough, shortness of breath, and chest pain, which could align with the patient's presentation.
Chronic Bronchitis: The patient's 2-year history of smoking cigarettes increases the risk for chronic bronchitis, which can cause a chronic cough and wheezing.
Acute Bronchitis: This is another possibility, especially if the patient has been exposed to respiratory pathogens. The cough and wheezing could be part of the symptom complex.

Pneumonia: Although less likely given the lack of fever or localized lung findings, pneumonia is a critical diagnosis not to miss due to its potential severity and need for prompt antibiotic treatment.
Pulmonary Embolism: While wheezing is not a typical presentation, in a patient with risk factors (e.g., recent travel, immobility), pulmonary embolism must be considered due to its high mortality if untreated.
Cancer (e.g., Bronchogenic Carcinoma): Although rare in a 32-year-old, a new onset of symptoms like cough and wheezing in a smoker warrants consideration of malignancy, especially if symptoms persist or worsen over time.

Allergic Bronchopulmonary Aspergillosis (ABPA): This condition occurs in asthmatic patients and can cause worsening of asthma symptoms, including cough and wheezing, but it is less common.
Cystic Fibrosis: Typically diagnosed in childhood, but mild forms can present later in life with respiratory symptoms like chronic cough and wheezing.
Bronchiolitis Obliterans: A rare condition that can cause obstructive lung disease symptoms, including cough and wheezing, often following a respiratory insult.
