We aren't the only game in town. Other labs provide support services for drug checking and we encourage you to check them out. Many programs have contracts with more than one lab to answer different types of questions.
Below is a short list of labs that we feel have scientifically rigorous methods. You may also find local university labs that can meet your drug checking needs.
Questions to ask
- What is the cost per sample?
- What is your turn around time?
- How do we send samples?
- Do you search for all drugs, or a subset of common ones?
- How are results delivered?
- Do you work with law enforcement?
- How long is the contract period? Are there minimums we must meet?
- How do you help programs interpret results?
