The problem of marijuana in your community isn't that big.
It's a fact that many people who really need it as a medicine,are jailed,same with people who are using it for recreational purposes. It is stupid that people are getting their life's destroyed thank's to some plant.

In my country,you may get up to 3 years in prison for possession of ANY amount of marijuana,and you get op to 10 years if it is a big amount (depends how much).

I know many stories where my friend with 1 gram got his life ruined,the police in our country is brutal to us,when police found out that i have some marijuana with me,they were beating me off for some time,because i did not want to say where i got it.
Marijuana should be free,but consider that some countries have bigger problems with law than you actually have.
