Back when my friends sometimes referred to me as The red eyed reefa monki I was living in a converted garage on the property of my landlord. One early morning I got a knock on the door and it was customs. They had a warrant to search the landlords property and as the garage was on it they got to search my place as well.
Seems the landlord knew an idiot in England who thought it was a good idea to send hash through the mail. Also turns out that in the greenhouse behind my garage were about 25 dope plants.
Fortunately I had been burgled about 3 weeks earlier and all my hydroponic stuff had been stolen out of my closet - including what I had been growing. The customs guy asked me if he would find anything. I showed him my smoking pipe (which was actually a sherlock holmes style pipe), they put the sniffer dog through, gave me the pipe back and said have a nice day.
I decided I really wasn't that interested in hydroponics after that.
