Well it depends.
I personally think it should be. In Europe we can travel to a country called the Netherlands where weed is legal and highly appreciated. you can find dedicated stores and even a museum in the capital city.
About the medical use i think in my country it's alrdy allowed but i'm not sure. I do know some doctors use it to cure things such as depressive mood, though.
Then again, sensemilia eats up your memory, which might be bad if young students started to use it regularly.
I'm happy that i'm no politic, so i don't have to deal with this anyways. And even if its not legal you can still find it quite easily lol.
