Any substance that can rev up the central nervous system-most especially caffeine, diet pills, cocaine, and speed.

Substances that depress the central nervous system (like alcohol, tranquilizers, sleeping pills, narcotics) can cause anxiety when they are withdrawn.

Prescription medications can cause anxiety, especially those that are used to treat asthma, high blood pressure, and Parkinson's disease. The antidepressant and antipsychotic medications sometimes have anxiety as a potential side effect.

Medical problems such as cardiovascular disease or oversecretion of thyroid, adrenal, or parathyroid hormone must also be considered as a possible cause of anxiety.

Anxiety is often an associated feature of another psychiatric disorder, such as depression.
