Definitely decriminalise it
Then should people wish to smoke weed they can make an informed decision and grow it at home
By doing this they can choose which type of weed to grow .....clearly sensibly avoiding the super skunk brands
And by legally growing their own weed they don't get a criminal record and they don't have to put themselves in contact with the criminal gangs commercially growing the stuff with the associated hassle that brings
It's a very simple solution but we live in a stupid country
