Residual Solvents

Medical cannabis consumers are increasingly choosing potent cannabis concentrates over traditional flower material. These concentrates contain medicinally active cannabinoids and terpenes, often extracted using organic chemical solvents. While the use of cannabis extracts instead of raw plant material eliminates many risks associated with smoking, cannabis concentrates can pose different health hazards if they are not free of residual solvents used in the extraction process. Toxic solvents remaining in medicinal products are likely to cause adverse health effects, including cancer, reproductive harm, damage to the nervous system, lungs, kidneys, and liver. Therefore, the Maryland Medical Cannabis Commission specifies strict upper limits for residual solvent concentrations.

Pinnacle CT is dedicated to ensuring the safety of medical cannabis extracts by using advanced instrumentation to measure residual solvents through GC-MS methods. We perform all residual solvent tests required by the state of Maryland, including assays for:

  • Benzene
  • Butanes
  • Ethanol
  • Heptanes
  • Hexanes
  • Propanes
  • Toluene
  • Xylenes
