this thread isnt very good as diff laws apply to diff cities and countries around the world.
1. Universal law is keep your house completely clean of any evidence....for extreme countries like the UK where shit is dark...not even nozzles (caps).
If you stick to this rule then what ever country you live in you will probably save yourself alot of trouble.
If you slip up then you got yourself to blame.....to us its fun but to them its a serious crime because it represents the uncontrollable, uncensored, free speech and free art. FUK THE SYSTEM!
