I think it's more likely that C. sativa will be extinct before it is legalised; the U.S. government is aggressively funding research into biological agents for ridding the world of this evil plant species once and for all. Mind you, given that chocolate and THC are in some way related, don't be too surprised if such a zealous virus ends up ridding the world of chocolate as well. Oh well, a small price to pay for victory against evil.
