Breathing test for people who use drugs or alcohol
Part of Brain & nervous system, Cancer, Immune system & allergy, Infections, Lungs & breathing, Mental health clinical trials.
This study is developing a simple breathing test to check how your lungs are doing if you use drugs or alcohol. You'll have breathing tests and answer some questions about your health and substance use.
Summary written for real people, not researchers, by Clin2.

- You are 18 or older.
- You have smoked tobacco, cannabis, cocaine, opioids, or drank alcohol in the last 28 days.

This study uses a simple breath test to detect different lung diseases. By analyzing the chemicals in your breath, researchers hope to find a faster, non-invasive way to diagnose lung conditions. It may be an option if you have a known lung disease and have a recent CT scan.
This trial tests how well different breathing tests measure relief from shortness of breath in people with asthma or COPD. It may help doctors find better ways to check how well treatments are working.
This study tests a new device that listens to your breathing to check lung health. It is for healthy people and those with asthma, COPD, CF, or other airway diseases.
This study tests a new portable device that measures how well your lungs work by having you breathe into a mouthpiece. Researchers want to see if this device can accurately identify different chronic lung conditions like COPD, asthma, bronchiectasis, and others.
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
This trial tests a portable “positive pressure” breathing device in people with severe COPD to see how well it works and whether it’s safe. It may help if you have trouble breathing and meet the device and health requirements.
