My roomie went and picked up a new kind of extract artist now available in San Diego. They're called Cowboy Extracts, and supposedly, their claim to fame is that they make wax with non-polar solvents, which leave no residual solvents at all. Here is a pic of what he picked up: http://i.imgur.com/sY1RA9n.jpg L-R is Blue Dot, Joker OG and Kosher Kush. Now, the reason why I say "non-polar solvents" instead of specifying which one, it's because we haven't gotten a straight answer on what they actually use. All of the dispensaries say they they are made using "supercritical fluids". But they differ on what fluid it actually is. One place says it's CO2, which I think is BS, since all CO2 waxes I've seen are saps, and they're in syringes. One place said it's just Oxygen. The most common answer (3 places so far) have said they use Nitrogen. What's strange to me, though, is that Cowboy Extract's webpage doesn't mention using any of these. Regardless, two places claimed that Cowboy Extracts is tested by SteepHills-Halent. I asked how I can view the results and am waiting for a response. Regardless, I was surprised at these. They're appear to be very quality, and taste and smell good. The Blue Dot especially smells very piney. The Kosher Kush sparkles in light. If California ends up banning concentrates made with BHO, this might be the way wax is made in the future. Assuming my roommate isn't being lied to, I could definitely see this taking market share from BHO products. Best of all, it was only $25 per 0.5g.
