The verdict is in. A cross fade is more than your run-of-the-mill fubar, stumble, mumble and grumble routine. At least according to a recent study done at the University of Iowa.

The study, conducted with 19 participants of varying weediness, measured the THC levels in the individual’s’ blood both with and without imbibing in some alcohol. All participants would vaporize the flower from a Volcano at their leisure, then repeat with the inclusion of the booze.

Specifically chosen were people who smoke not excessively but closer to occasionally– on the few times a week end of the discussion. The researchers found that the blood here would show the changes greatest and most steadily, so occasional smokers is what they got.

What they found was an increase in the level of THC in the blood of those participants who had knocked a few back. A slight one. And a pretty major increase in the THC metabolites of the drinkey smokers. But what’s really interesting here, is that they still can’t prove the chemical combination to be the cause of the increase.

Having allowed the subjects to smoke and drink at roughly their own pace, the study can’t truly outlay the specifics of the chemical interaction. What could have occurred is the simple loss of inhibition that comes along with our friend the drunk.

The researchers stressed to not forget that “it is … possible that our higher blood cannabinoid Cmax reflects less careful cannabis self-titration after alcohol.”

That’s not to say that some chemical inter/reaction isn’t going on, because they’re sure it is.

What they’re really trying to say, or rather find, is a way to be more specific and accurate in blood testing, and/or on-site testing for officials on the roadways– and as such, the varying degrees of influence a driver or user could be under with marijuana, if there are more than one.

As legality becomes more rampant, the regulation for operating vehicles and machinery among so many other things, must come into the fold. And although THC metabolites may be more commonly found in the blood of more regular smokers, that doesn’t always mean they are not sober or under the influence of psychoactives.

This research is drilling deeper into specific and better ways to figure just that out, so that the next time an innocent person isn’t put away just because they be gettin their smoke on–with ample time before they had to get behind the wheel of a car.
