You can smell it. Most weed is bought from a known person. They still sell untaxed ditch weed in Colorado. As a matter of fact, they may sell more untaxed than taxed. $80 for an 1/8 is pretty high.
See what I did there?
How does the ‘known’ person know where it comes from? Who grows it and even what country it’s from? There are no guarantees how many hands it’s passed through.
