Where I live getting caught having under 28 grams is like a parking ticket, but more expensive. It is illegal to grow, but police here regularly bust houses with 100 or more plants, so its not exactly cost effective for them to target your average 'personal pot' grower who has maybe a dozen plants..
Funny story about the legality of smoking it..
One day on my way home from a long shift at work I decided to reward myself with a joint or two (its a long drive) So Im driving on some back roads to get back to my house, doing about 90 km/h in a 50 km/h zone (which is a $356 ticket by the way) and I light up a big fat joint..normally when Im driving I wear a seat belt but this particular time Im driving home I borrowed my friend's car which happened to be a nicely built up Jeep 4x4, so I didnt deem the seat belt necessary.
This drive takes me by a local mud pit and it just so happens my friend spent 2 hours washing & polishing his pretty jeep the day before (he built it up and NEVER 4x4s it, damn waste) so I decide to try it out in the mud. It performs admirably, so well in fact I decide to hop the 4 foot embankment to get back on the road, I got about 3 feet of air from the front tires, like a big wheely and came down pretty damn hard, with no damage luckily. Unfortunately I decided to jump back onto the road right in front of a cop who already has someone pulled over. By this time I had lit up another fatty, and he looks at me smoking my doobie, not wearing a seatbelt doing some pretty damn reckless driving and mouths "Get the **** outta my sight." At which point I promptly smile and wave, and drive away.
The guy he pulled over before me must've done something real bad.
