ive seen weed befor but how can you tell the differences between the different types that are out there?
danker weed always has a fresher smelling taste than reggies. many people try to do shit to their commercial weed in attempts to raise the quality such as adding orange peels ect. to add moisture to bud, ive even heard of people pissing on pounds of weed to add moisture, which is fucking sick! like they said look for seeds, if you see seeds and don't want some commercial bud don't buy it.
as for dank weed, it is hard to tell what the smell would be because they all have different ones. look for crystals, if you don't know what they look like take a look at some of the pics on here and you will see some dank nugs! it will help you differentiate. if you look in mags too you can always see some bomb nugs.
