Most of us know how to best keep their stash stored. Many probably started keeping their grass in containers, whether the metal tin you bought in the headshop and kept your single grams in, or in a storage container at home.
The smarter and more dedicated cannasseurs probably moved from plastic containers, or a wooden box, to glass storage containers because glass is neutral and doesn’t change the product’s flavor nor deteriorates itself.
One thing most users have in common, no matter which medium they prefer to keep their stash in is that they store their weed at room temperature. Many will say that they can easily keep their weed at high quality for weeks, months, and maybe even a year.
That may be wrong, as an Italian study highlighted. The study, directed by researchers from the University of Padua and the AULSS# Serenissima in Venice, Italy, analyses how different methods of storing cannabis impacted the THC levels over time.
The researchers analyzed the difference in quality between marijuana kept in light or dark places. They also looked at changes between weed kept at room temperature, chilled at 4 degrees Celsius in the fridge, and kept in the freezer at -20 degrees Celsius.
After 100 days, cannabis kept in a bright room and stored at room temperature had lost 13% of its THC level. The best result was obtained when storing the cannabis in the freezer, at -20 Celsius, which resulted in no noticeable change in THC content.
“Freezing is the best storage condition to avoid the reduction of the cannabinoids content over time”
When the researchers analyzed high CBD cannabis, the results changed. High CBD cannabis didn’t deteriorate over time in the same way as high THC contents did. In fact, barely any change was observed and the CBD levels stayed relatively constant over time.
Obviously, age may also have an impact on the flavor of your weed and its terpes. Luckily, for most of us this is mostly a non-issue I think. Because who will keep their weed for a months?
Yet, it may be of importance for our more prolific growers here at Smoke.io. Now you know it: if you love your THC and grow copious amounts of ganja for yourself, this is where you want to keep it all.
Because the study was in Italy and Cannabiss is still scheduled in the country, the researchers had to work with cannabis confiscated by the local police force. The new EU directive which will allow (medical) research on marijuana can’t come quick enough.
