The product known as "Spice", "K-2", or SYNTHETIC MARIJUANA is, in fact, ILLEGAL to POSSESS.
Many people feel that, since Spice can be legally bought at so-called "head shops" or "smoke shops", they can possess it without consequence. They would be incorrect. While I am optimistic that there are some possible ways to attack it, the better course of action is to avoid it. The fact of the matter is that it is punished under 18.2-250 of the Virginia Code as "possession of a controlled substance".
