X mean how many times stronger it is than the unextracted active ingredient in the leaves. What you are smoking would be a black power that smells like Robotussin. Depending on how many "x" it is determines the potency of the drug, for example 5x is weak compared to 20x (which i did) and will fuck you up. 1 gram of this powder that comes in a vile, its not really powder it just looks like and you can smoke it out of a bowl, is usually around $40/gram at a headshop. I CANNOT EMPHASIZE THIS ENOUGH, SALVIA DIVINORUM IS NOT A PARTY DRUG it is to be used in a calm environment or you will regret it.
