What Is The % Strength Of The Actual Smoke/vapor?

Discussion in 'Seasoned Marijuana Users' started by tstick, Jun 12, 2014.

  1. I would reckon that a lot of that % number is quite a bit lower when it's burned or vaporized.
     
    Has anyone tested the potency of what is actually inhaled?

     
  2. 90% in vapor

  3.  
    Cite your sources. Nobody believes that shit
     
  4. if you're talking about the thc percentage they're between 15-20% for the best strains. If your talking about the actual ratio of thc atoms to carcinogens in the smoke well thats impossible

    No….I suggested nothing about carcinogens. I am suggesting that the % of THC that is reported in lab tests for potency, doesn't really apply to the smoke or vapor. It applies to the pre-combusted substance -be it flower or oil, etc. And we all know that THC is destroyed in the presence of heat, so I am asking why someone doesn't test the actual inhaled form of the drug -as opposed to the "unactivated" (for lack of a better term) form. I think this could be done in the lab, as well. All they would have to do is to take the weed, oil etc. and produce some smoke or vapor and then test that
     
    I would wager that the % of THC that actually goes into one's system is MUCH lower than the high test % show for the pre-combusted form.

    This is something Ive always wondered about, but I can't find any research on it. Anyone know if the percentage of thc in the flower itself is measured by weight or volume?

    I believe that many of those tests are done with a gas chromatograph, which vaporizes the flowers or concentrate and then measures the percentages based on the gases, not the actual product. Don't quote me on that... 
    -so those lab test results might be the actual numbers of the vapor produced by the product
     
  8. I'm not sure how they determine that %.
     
    But, I'll say this much….I'll bet ANYONE cash money that, if you went to any dispensary, at any time and took a random sample of any of the buds that supposedly have tested to be 20-30% THC, that random sample will not test out to be the same.
     
    Even different buds taken from the same exact plant, will not test the same….in my suspicion, anyway. Therefore, those labels are really kind of pointless and are used to embellish the marketing aspect -as opposed to the true medicinal characteristics of the given plant.

    Didn't see this post before I posted! That's very interesting. I think you may be correct! 
     
  9. I'd say probably about 6-9% thc in the smoke from your average puff.
     
  10. Too many variables to say. If you torch the bowl you will burn off and waste more thc. If you use a flame that's not as hot (hempwick) your going to burn off less thc. And even with vaporizers, you can't just give a solid number (like 90%) because the heating elements in different vapes heat up to different temps.


    More heat = less THC.

    IMO. Not entirely true. For example, the vaporisator does not provide all of the different cannabinoids. And when I smoking for joint, all shit burn and I get everything. In fact, from the vaporisatoror, I do not get what I need. Some of the cannabinoids what my body wants, unfortunately, unburned. And Effect is 1/10.
     
    1g joint and I get what I want. Vaped 10g, No effect... But that's just me.  :confused_2:
     
  12. Well let's see...say youve got some good fire dank, say 30% THC. Combusting (smoking) it will give you around 80-85% of the THC, while vaping gives you percents in the 90s. So your average hit is still about 25%. Luckily THC is not water soluble so smoking it through any smoking piece, including bongs and bubblers, would not decrease the potency.
     
    Pretty much if you smoke weed you will get high.
     
  13. You are correct. We performed them at the University of Florida for $50 a pop! Not for cannabis though, but it works the same. Peace!
     
  14. The curiosity rover on Mars has a lab built into it that could test precisely for all of the matter being expelled from baking any substance it places in there, so you could easily do this collect the data and find where the peaks of assorted cannabinoids at different tempature a for a specific strain I'm betting.
     
  15. There was a chart on what temps which chemical sublimes at.

    So some vapes can get cbd's and the likes but i think its beyond pretty much most portable vapes let alone pens.

    However ill.look for the chart and i dont vape so take my words lightly.
     
  16. That could be another reason why edibles fuck you up badly
     
  17. Strongest bud ever recorded at a cannabis cup was just over 27%....
     
  18. First, the percentage of THCA (Tetrahydrocannabinolic Acid), the biosynthetic precursor of THC, is measured.  Very little actual THC exists on fresh cannabis.  THCA is converted to THC through decarboxylation.  Decarboxylation occurs slowly over time as the bud dries, as well as with exposure to heat.  When the bud is burned or vaporized, THCA is decarboxylated instantly.
    Second, according to my understanding, the THCA is artificially decarboxylated in the lab to obtain the actual THC%.  I'm unsure if labs measure the endogenous THC level and add that to the total percentage, but regardless, the actual THC% is always significantly lower than the THCA%.  (I've noticed dispensaries inflating their advertised test results by only reporting the THCA% and calling it the "THC%".)
    Third, ~63% maximum of the cannabinoids are absorbed when smoked. (http://steephilllab.com/resources/ "Understanding Medical Cannabis" pg. 16)
     
  19. it depends.

    If you smoke out of a bong, then the micro-bioluminent filters or "Percs" as some call them will turn any weed into crystallized THCA2, which will un-solidify in your lungs, hence getting you the most high. ~90% THC

    Joints don't have this, but rather have special chemicals in the paper that release alkaloids, converting FFM, BBC, and BBW into THC, when you give the final rolled product a quick bath in water.  This is known as "baptizing the joint" ~ 47% THC
     
    Vaporizers use an atomizing molecule electro-proton to basically make THC out of the red "keifs" or "hairs" without even burning your bud! ~ 85% THC

    Pipes work by putting a flame to some marijuana and shotgunning the smoke into your chest cavity. ~ 666% THC
     
  20. Okay, I understand the last percentage was for 'fun'. But this^ is entirely false. Do not spread misinformation. Most flowers can only reach 23%thc. Maybe 25. Concentrates reach upwards of 85%. But that's shatter. And even then. If you don't purge correctly it messes up the THC content massively.

    So now we have this in mind. The way the drug get introduced to the brain is called bioavailability. You lose some of your drug smoking joints versus vaping. It's just the efficiency. So now, you have a theoretical product of 23%thc(lol good luck finding this on the streets, since most is 15%thc on a good day.) but smoking a joint (to some sources online, wikipedia) is about 20%. So 20% of 23%. It was noted on the article that a avid smoker got upwards of 40% though. So to each is his own.
