How do I know what medicine to purchase for my condition?

Our qualified staff will work closely with each patient to determine the strain or type of medicine that is best suited for your treatment.

Is your location secure?

TCS employs a professional security team that respects the patient-centered atmosphere of the facility. The property is highly secure with a well-lit parking area and 24-hour monitoring.


The Thomas C. Slater Compassion Center will only be providing the finest medical grade cannabis.

This is ensured by the specialists at the dispensary as well as a certified laboratory.

This laboratory will be testing for potency and a safety screening using state of the art equipment and technology.


Potency tests will provide vital statistics on the amount of active cannabinoids in the medicine. Whether it is a flower, edible, or extract, the percentage of THC, CBD, and CBN will be indicated.

This is useful in determining the correct dosage, so that a patient can ascertain the amount of medicine present in milligrams. For instance, if a flower comes back with 16.5% CBD and 7.5% THC, it means there is 165 milligrams of CBD and 75 milligrams of THC per gram of medicine.



A safety screening is performed by the dispensary, and the laboratory. For the screening we mainly look for signs of decay, such as bud rot or mold, etc.

The lab has the capacity to be more extensive as their equipment lets them get an in depth analysis, and will eventually be able to test for pesticides as well.


What a nice variety.. you guys have been kicking butt!!! Thanks again!
