Piff??

Okay so I bought some weed called piff, its smells like old socks or cheese. The texture is fluffy but it dosent resemble any weed i smoke like good strains that we usually see. It came with some stems and no seeds. When i did research on it people say its marijauna mixed with opiates, know i dont know if thats true but the weed has a very fluffy feeling and its not sticky and kind of seems to have some cotton thing going on with it, somehow it looks like a legal herb. So i smoked it and got a little buzz but not high. If it where to resemble any strain I smoke then I say silver haze becuase it has that silver look to it. Someone tell me what the hell this is, im not buying from this guy again, he showed me some Sour D, which look like sour d, but this look like i dont know. Inspecting it more closely the stems have thricomes but the leaves look like and feel like a light green brush.
