Rather, you should break all unjust laws
Eh...can't say as that's a great idea.
Bear in mind laws are created to uphold social values, just because you think something's ok doesn't mean society does.
Case in point: Uninsured drivers do so to avoid paying huge insurance fees, people hit by uninsured drivers are shit out of luck. Cannabis use isn't necessarily bad in and of itself, but look at smuggling (I come from a country where it's not native and won't grow in the wild even if introduced, not for more than four months or so anyway) and there are definitely victims of cannabis smugglers!
Your definition of 'unjust' isn't necessarily the same as everyone else's.
