Where does Amsterdam get marijuana from?

Marijuana is widely grown around Amsterdam and The Netherlands. There are limitations to the amt. each individual can grow, but authorities look the other way when coffee-shops receive large quantities from contracted growers. Many shops have strands that are unique to their menu, these varieties of weed are grown by individuals exclusively for the shops.

Remember, Weed isn't legal in Amsterdam, its decriminalized like many places in the United States. The Dutch authorities simply choose to enforce "hard drugs" like cocaine and heroine instead of "soft drugs" like marijuana and mushrooms.
