Erowid's interactions information is a summary of data gathered from first hand reports, research, and other resources. This page is intended to collect drug-drug and biology-drug interactions and is not exhaustive: other dangerous or medically important interactions may exist that are not listed here. Drug effects may vary dramatically from one person to another and from one experience to another based on a variety of factors such as body chemistry, age, gender, physical health, dose, and form of material.
