News outlets are fond of reporting about research showing “links” between particular chemicals and occurrences of cancer and other diseases. Sometimes the stories even claim that a substance definitely causes cancer or definitely cures it. But more often than not these reports only cover part of the scientists’ conclusions. They just mention that an effect on cancer (either positively or negatively) was seen in the presence of a chemical. This is what we call a correlation, but it does not necessarily imply a causal link. Exemplo. Cannabis sativa.
