In dc there’s this guy that sell this type of k2 blend that when you take 2-3 puffs you nodding off to sleep and wake up 5-10 minutes later it and it’s addictive Anyone know What kind of synthetic cannabinoid is that or do one of you guys know what’s synthetic cannabinoid that has the same effect?

Who the fuck knows. Every Noid that is popular nowadays does what you describe. It's not a fun high, you repeat this over and over till you run out, then you fiend for more like a crack addict. Be careful, this shit isn't bud.

Not to be a dick, but the whole thing about K2 blends is usually you don't know what's in them. If it was easy to tell, the government would have an easier time identifying the chems and banning them. Most 'noids have similar effects, too. Only way to know for sure is to get a sample of it tested. You can however check this list and maybe do some comparison via erowid reports. There's really no way of telling for sure. Sorry I can't be of anymore help

It can’t be a synthetic opium
