Yes, it's fucking pathetic to mix synthetic cannabinoids with marijuana. Your ability to communicate right now sort of illustrates my point.
Spike is the shizzzzzz!!!! I don't care what anyone says. Of course, I think I've only tried Spike Gold, so I'm not sure about Spike Silver. The one I tried got me every bit as stoned as the dankest of the dank though, and the high lasted for 5+ hours.
But if you have pot there NEXT TO it? And that shit doesn't feel the same, at least to me. They tend to have strange, unfamiliar body loads and feelings that I don't enjoy, combined with marked resperatory depression and other negative effects.
Oh, if I have weed, then there will be no fake shit smoked. I've never gotten any of those negative effects though, so I WILL smoke it when I don't have weed.
