Yes but not smelling: Caffeine, the drug in coffee, has the same chemical formula as theophylline, a drug commonly used to treat asthma 25 years ago. While these drugs share the same chemical formula their 3-dimensional structures differ. That renders caffeine 100x less potent than theophylline as a bronchodilator but equally potent for side-effects. Caffeine is not recommended for the treatment of asthma.

Caffeine...: Caffeine is a bronchodilator but you would have to ingest an awful lot to have this effect and you would suffer many side-effects. It is clinically better if you take the bronchodilator inhalers prescribed by your doctor. These give more bronchodilation with far less side-effects.
