McGill University's free, homegrown drug checking & harm reduction service

Dear user,

Welcome to McGill University’s drug checking service, as envisioned by members of your Canadian Students for Sensible Drug Policy.

This is the result of two years of work. It is our pleasure to finally deliver it to you.

You will be dealing with potentially hazardous chemicals, so it is really, really important that you read everything carefully. You are responsible for whatever decision you make, so make them informed ones. 

If you’d like to know what drug checking is and why the McGill environment demands it, please refer here

For pointers about general harm reduction, please refer to here

For a step by step guide on how to use our service, please refer to here.

If you’d like to educate yourself on the drug war and your potential role in it, please read these books.

We’re so excited to finally get this off the ground, and we’d like to thank Health Canada, the CSSDP and SACOMSS for realising this dream of ours. 

All our love,


How it works:

1. Read documentation, understand strengths and limitations.

2. Make specific reagent request with unique and anonymous reference code.

3. Message our socials with unique reference code to organize collection.

4. Conduct check with relevant safety procedures. Dispose of sample.

5. Reflect, empowered with information. Take responsibility.


Making Drugs More Accurate is not responsible for what you do with this information. Nor do we recommend drug use and we emphasize all drug use carries risk. 

The information outlined on this website is not exhaustive. We provide a brief description of drugs that are commonly used recreationally, including typical routes of administration, typical doses, common effects and their duration, as well as other helpful information. The effects described are the most commonly reported effects, but because the purity of substances cannot be assured, effects can vary as a result of the potential for contaminants.

Feeling generous? All donations will go to more reagents :)
