I was thinking, because Salvia is soon to become illegal would it be possible to buy a large amount before this happens and keep it? or would this result in the salvia "going off"? thanks in advance
Friend, salvia is *not* soon to become illegal. Those are just rumours. The bill has been in Congress for years, and Congress is doing nothing to pass it.
aggreed not going illegal though it is a marginal kind of thing. but sure it keeps even if wetted and mouldy it still smokes fine after it is redried and stored properly for a l....ong time.
