One plant with no previous criminal record? Probably suspended sentence like Sabai says. You'll be banned from the country for life though.
theres no fine for weed...worst case is jail for up to 7 years and then deportation...best case is a suspended sentence for 1-3 years.
Never heard of anything like that. I know a guy who was caught with hundreds of X, grass and meth got off, but his father is in the Govt.
I had a GF Junko who loved to smoke as well as other things, you would be suprised. Just Be careful and pay the high Prices.
