Finland is wrong.
"Often unenforced"
Who the fuck made this inforgraphic?
Finnish cops are obsessive over fighting cannabis, and in practice even having a single joint on you will lead to a criminal record, and not for just "personal use" or "possession" but the same crime you'd be charged with if you grow 27 plants at home.
And yes, I've personal experience on both, as well as several dozens of other examples, documented and otherwise.
Finnish drug laws are just as archaic as others, and the cops attitude and understanding is way worse than in most European countries.
It's ridiculous.
So yeah, Finland is definitely wrong, fucking hell.
