There are many ways to differentiate between “kind bud” (excellent quality weed) and “dirt” (poor quality weed).
Smell. Great weed can have a wide variety of smells. The scent of pine trees and skunks, for example, are both common indicators of good pot.
Look. Good weed usually consists of medium to large buds with little or no stems. Kind buds may also have a crystalline quality. These buds will often be bright green with orange, red, or purple hairs.
Feel. Quality weed is usually soft, light, and sticky to the touch but not wet.
“High.” Finally, you can always tell a fine weed by the “high” you achieve after testing a sample. Great weed should inspire you creatively without that heavy “burnt-out” feeling sometimes associated with lesser quality marijuana.
