If cannabis plant material is not dried to water activity levels below 0.65 Aw, they can support mold growth during storage and transport, leading to the subsequent potential for inhalation of mold spores or mycotoxins. In addition, water activity controls the rate of decarboxylation that can lead to the breakdown of delta-9-tetrahydrocannabinol (∆-9-THC). Additionally, water activity is correlated to additional critical product quality attributes that are associated with shelf life.  

OA utilizes the AquaLab TDL2 instrument to determine both the water activity and moisture content of your cannabis sample.
