describe the two types of data collected in the DAWN systems, and know the top four drug classes for emergency room visit and mortality

Date: Thu-Dec-1-2016-
The Drug Abuse Warning System, known by its acronym DAWN, collects data on drug-related emergency room visits and drug-related deaths. The data from DAWN should be viewed in conjunction with information on the relative usage rates of a drug. For example, heroin and cocaine have high risks of toxicity per user, but their overall public health impact is low compared to that of tobacco and alcohol, which are much more widely used. Prescription drugs are also important contributors to overall statistics on drug toxicity. People who inject drugs face the specific toxicity risk of HIV infection and other blood-borne diseases.
