before you start
this tool provides harm reduction information based on published pharmacological data. it is not medical advice.
every body metabolizes substances differently. factors like weight, tolerance, hydration, sleep, and other medications all change the equation. the timing and risk data here represent averages, not guarantees.
this tool cannot account for substance purity or dosing accuracy. always test your substances. always tell someone what you've taken. always know where the nearest exit is.
if something goes wrong, call emergency services. they are there to help you, not to judge you.
