The amount of Myrcene in a cannabis sample is what dictates the indica or sativa effect. If a sample has over 0.5% Myrcene than it will have the indica, or couch-lock effect. If a sample has less than the 0.5% level of Myrcene, it will have the soaring Sativa effect. It is simply the amount of myrcene that is in the sample that dictates how you will be effected.


Next time you get your cannabis tested, get a terpene test on your flower or oil and see if that OG you are running is sativa or indica dominant. This is a fun way of knowing more about your medicine and also a good way to decide if something is gonna be a good nighttime or daytime medicine.

That's not really true....,
Besides the cannabinoid effect. One could argue myrcene is an indicator of a sativa not indica... most south american land races are mango sativas. And when in sufficient quantity gives a nice euphoric trippy high, easing thc's transition in then intensifying its effects..it does have somewhat sedative like qualities that tame the racy high but hardly qualifies as couch lock. Its most known for its face grinning qualities and making the experience more psychedelic..... its relaxing effects come from its opiate like qualities that can be mediated by an antagonist like naloxone

You should use this site to read and learn not spout.....

Dude Qwiso, I am sure these guys know their shit!

I recommend you read what they put out considering the amount of cannabis and concentrates they test, and since they have statistics to back up their claims...

Steep Hill is located in California and while S.H. puts out a lot of nice information, California is not exactly the mecca for true sativas.

I am a firm believer that the cannabinoid profile and the terpene profile both affect the type of high you feel. For example CBD alone will not get you high but it will alter the effects you feel from THC and other cannabinoids, I believe terpenes work in a similar fashion.

Just out of curiosity, which strains have you tested that have the highest levels of myrcene?

Exactly what material are you testing, where, and how? I've been puzzled as to the measurements. I doubt if there's any standards for exactly what is supposed to be tested and how.

I've tested flowers and concentrate (hash). I use a lab here in Michigan called Iron Laboratories, they use gas chromatograph - flame ionization detector.

Check their site, they list everything you want to know. http://www.ironlabsllc.co/

They also list all their results publicly on the site (as long as the member hasn't set their results to private), you can click each cannabinoid to arrange results from lowest to highest or vice versa. Their site is a pretty good tool to use, be sure to change the default setting in the results from 1 month to 3 years to get a full list of all their test results rather than just what has been tested in the last month.

They may be "OPIATE LIKE QUALITIES" but they are not actual opiates.
So I doubt that an OPIOID ANTAGONIST, such as NALOXONE, would 'mediate' the effects.

Naloxone works by blocking Opioid Neuro-Transmitters and Receptors DELTA, KAPPA, SIGMA and MU.
Having said that...the most recent research into these Opioid Antagonists has found that they help recovering alcoholics to remain sober -
most think they do this by lessening the severity of depressed moods related to post physical withdrawal abstinence.
It is now being said that NALOXONE (or NALTREXONE) also mitigate that levels of damage that substance misuse can cause the liver.


So my scepticism that NALOXONE could alter the affects of cannabinoids is less certain that it would have been a few short years ago.
But I'm still doubtful...

Lol maybe you should just Google it..
Or we can discuss the pharmacodynamics of it..

Yes myrcene actually speeds thcs uptake in, intensifying effects similar to a high thcv strain. Now again myrcene dominant strains originate in south America. They do not produce couch lock at all..notice cbd levels in the test shown, that's the factor here. Yes terpenes do drastically effect the high. But he's just wrong..

Now I'll just help you .. . "The antinociceptive effect was significantly antagonized by naloxone (1 mg kg-1) or yohimbine (2 mg kg-1). The results suggest that myrcene is capable of inducing antinociception in mice, probably mediated by alpha 2-adrenoceptor stimulated release of endogenous opioids."
I know big word....

As I think you know...not our first conversation...I have a pharm D. And am well aware of what's going on here..also I only grow landrace s.a sativas

How are they getting around the law? Don't mean to beat a dead horse, but I thought this kind of stuff was illegal.
