What does Dub Sack mean?
A dub sack is a measure of cannabis that costs $20. It’s not really a weight as prices are different around the world, yet a dub sack is always $20 worth of weed.

Back in the day, a dub sack was a lot of herb. Now the amount you get for $20 is way less and going into a dispensary asking for a dub sack may not get you a bag of herb for $20 as it is an older term not used much today.
