At least it is legal here in California but the city I live in is fairly restrictive.
1. No growing outside
2. Maximum of 6 plants
3. No smoking inside you residence (420 or Cigarettes) if it is connected to another like an apartment or Condo.
4. No smoking marijuana in a public place -
While there are regulations the police no longer want to be involved.
tbh that sounds not to bad ... all 4 rules seem to aim at the non tokers to keep them from growing unhappy with the legalization ... i wouldn't per say see these extra limitations as oppressive ... beside 6 plants should give you all the weed you can smoke and then some ...
