I  also use  for  long term , the vac seal attachment that goes on top of the canning lid of the mason jar.  ( food saver) And removes the air without crushing the meds….     I would like to comment that however much one enjoys the smell of a LOUD strain..  I  do not want some company catching wind of it creeping through every crevice of my  home.   Even in the jar!!  For these bad boys …. I place them in a 5 gallon bucket with a Amazon purchased gamma lid. Bout 10 bux lid .    It’s airtight, screws on and off  super easy..  I’ve placed them right beside me for hours and nothing escapes ….    Stealth .        
* do NOT purchase gamma lid  from Home Depot. terrible . 
www.GAMMA2.net  made in USA 🇺🇸 Worth the spare change.  😊
