Breaking/disregarding bad laws has sometimes been a very good way to see said laws changed or abandoned. It is probably a safe bet that millions in North America are disregarding drug laws, possibly every day. The black market in controlled substances is a thriving one, showing that many will accept the risks imposed by the State, and participate in that economy regardless. Since those in power are still to some extent at the mercy of needing the consent of those they rule, the people can make a powerful statement by refusing to comply.
