The dominant strategy adopted to protect the public from drug abuse has been to heavily criminalize substance use and
adopt a "just say no" attitude surrounding substance use.
This has been a decades-long failed experiment: abstinence-only education doesn't work for sex education, and it definitely doesn't work for drug education either.
Campaigns of this nature, such as those adopted organizations such as D.A.R.E, have been observed to sometimes cause
a net increase in substance usage1,2.
Those who use substances often acquire them in dangerous ways, don't know if they are recieving a laced substance,
and are unsure of how to use it safely1,2.
And every day we fail to address these problems carries a body count.
2 — People should understand how to protect themselves
Using substances is not a moral failing. And, like it or not, there will always be people who choose to use drugs despite the risks.
Knowing this, our goal ought to be to minimize the number of overdoses as well as mitigate
other health problems posed by drug abuse.
However, a large amount of educational content, both online and in formal education, remains focused on
abstinence over harm reduction. If a substance user wants to know if something they are committed to
doing is safe, they will face a challenge finding accurate and relevant information. Resources such as Erowid1 have contributed
massively to harm reduction education, but do not offer streamlined tools for serving this function.
3 — We need easy to use tools for supporting drug eductation
This tool exists to make it easy for users
to identify potentially lethal substance interactions.
While not every interaction is covered on this website, users should take the listed risks seriously.
This tool is meant as a starting point — do your research, and be safe!
Please read this before continuing!
The information on this website is strictly for harm reduction purposes. I am not advising anyone to take substances of any kind.
Note that not every possible harmful combination is covered on this site, although many are. You are responsible for everything you do. Listen to the displayed risks — please be safe!
Support the project
This tool will always be free!
Hey! Thanks for using this tool :)
I'm a student rapidly approaching graduation, and my financial situation does not
currently allow me to work on projects like this full time. I've spent years putting out free tools
to assist with everything from cancer education to PTSD treatment1,
and want to spend as much time as possible on this work. Every bit of support helps me to do this!
You can click a substance to add it to the combination being analyzed.
They are organized by category, and there is no limit to how many you can select at once.
2 — Read about the risks
I have tried to approach risk classifications cautiously, and it is assumed that users are both
using the substance recreationally and are not practicing proper harm reduction techniques. Everybody's situation is different, but it is a good idea
to take all listed risks seriously.
Citations have been included that you can click on to access further reading.
3 — Do further research
Do not assume that a given substance combination is safe simply because no lethal interaction is found using this tool.
Combining substances quickly spirals into a complex web of interactions, and tracking them all can be difficult or impossible given the current state of limited research.
This tool is intended to be a supplement to your own research about what and how much you are taking. If a negative interaction is listed here, take it seriously.
