I just went to the Official Boveda site and happened to find this:

Boveda is the standard in proper herbal medicine storage.
Boveda is the global leader in 2-way humidity control. It’s engineered in a wide range of Rh (relative humidity) levels to regulate within 1% of the pre-determined Rh by responding to ambient conditions. Why is this important for medical cannabis?
Medical cannabis is the only medicine that is currently without FDA-regulated care/storage instructions. We believe medical cannabis can seize the initiative to further legitimize itself by recognizing the scientifically ideal Rh for herbal storage. In an effort to help medical cannabis gain wider sanctioning as a legal medicine, Boveda sponsored an independent
moisture sorption isotherm analysis on various strains over a wide range of Rh levels to objectively determine the ideal Rh for medical cannabis.
These results showed that cannabis is best preserved in a 59-63% Rh environment. For this reason, Boveda has recently released our 62% Rh product. Boveda benefits the entire industry by allowing quality control for farmers throughout distribution (Boveda is available in large sizes), controlled storage for dispensaries and proper at-home care for patients. And because you can preserve cannabis indefinitely with Boveda, patients can purchase more medicine without worry that it will be affected by the environment. Standard Rh storage is also important for products sold exclusively by weight. Dispensaries and patients should know exactly what they’re getting.
All Boveda perform best when in an air tight container and some
manufacturers have specifically designed their containers with Boveda in mind.
I guess they are catching up with people using it for cannabis.
