Why Is Glass a Better Option Over Plastic for Storing Cannabis?
Glass is considered a better option over plastic for storing cannabis primarily due to its non-reactive nature, which prevents chemical leaching and preserves the integrity of the cannabinoids and terpenes.
According to a study published in the Journal of Agricultural and Food Chemistry, glass containers do not interact with the contents they hold, unlike certain plastics that can release harmful substances over time, especially when exposed to heat or light. This quality ensures that the potency and flavor profile of cannabis remain intact, providing a superior experience for consumers.
The underlying mechanism for this advantage is that glass is inert and does not absorb moisture or odors, which can be a significant issue with plastic containers. Additionally, glass offers a better seal against air and humidity, reducing the chances of oxidation and degradation of the cannabis. When cannabis is stored in a sealed glass jar, it can maintain its freshness for a longer period, as demonstrated by research from the University of California, which highlights the importance of proper storage in preserving the quality of cannabis over time.
