Summary: The KMSK scale is a relatively rapid method to quantify self-exposure to opioids (including heroin and illicitly used prescription opioids), cocaine, alcohol, tobacco and cannabis, as well as other substances. The KMSK scale assesses the frequency, amount, and duration of exposure to each substance during a person’s period of greatest use (lifetime score). For each substance, the scale also has a separate form for measurement of use in the last 30 days. The KMSK also captures simple information on age trajectory, especially age of first use and age of heaviest use.
