Has anyone here experimented with adding extra terpenes (such as limonene, myrcene) to cannabis or cannabis extracts to enhance flavor and/or effects? Some of the terpenes have been shown to be modulators of the effects of THC, so adding them may increase effects significantly. In fact, most of the differences between strains is thought to be caused by their different terpene profiles. Additionally, the terpenes have their own medical values.

I got some foodsafe D-limonene and I am going to try adding it to enhanced leaf/hash oil/bud to see the results. Are there any other cannabis terpenes that can be easily obtained in pure form?

Interesting idea. Let us know how you get on!

Interesting idea indeed. A somewhat related article: Terpene Isolation Could Be The Future Of Cannabis.

other than subjectively pleasing scent (personally, i think toluene smells better) and high solubility (like dissolves like), Idk of any other advantages to using limonene or other terpenoid solvents i.e. potentiation; afaik, there is no potentiation

Check out the attached paper. There is definitely some synergy.

now explain what you got from that paper...
do you want to prevent breast cancer, or prevent cellular oxidative damage? how does that potentiate central activity?

anyone can post papers... but you have to explain the implications of the claims.

you also need to understand that receptors and enzymes operate on a principle of diminishing returns, i.e. downregulation, feedback inhibition, etc.

When making BHO I once added a drop of limonene essential oil, and drop of basil essential oil to the extraction tube, before the extraction process took place.

The product tasted great. Potentiation wasn't experienced.

To the O.P. : I had this thought also, but never went into experimentation.
Let's see and share results. I will be making more BHO, QWISO and other types of edible extracts.

I thought to start too with some of my citrus essential oil but then possibilities are endless ...

Arent at least some esential oils carcinogens ? Are the esential oils mentioned carcinogens ?

My personal opinion is that if someone feels the need to add things to cannabis to get more drug effect either they have crap or they have abused it / themselves so much that the full effects are not felt .

Yeah Im with benz here, I'd love to see some experimental data on this, appart from hypothesis.

I read a few times (in that paper included) claims regarding myrcene, for example the couchlock effects and how its a sedative, but the claims are kinda distant from the actual data. -> Yeah ok maybe some mice experiment showed some effect in some dosage, but what about in our relevant case, humans, and marijuana concentrations? Is myrcene analgesic at what dosages, what dosages are found in cannabis, what dosages are effectively ingested, how do those compounds act together with other compounds, is there competitive binding that prevents action, etc etc

Either way it's an interesting subject, maybe in the future we do get info that some of these compounds can affect the experience, maybe only in dosages not found in the plants but possibly when taken 'supplementally', or maybe there are no noticeable changes. Either way, I'll def be interested if you guys and gals find any further info

So I received some D-limonene, myrcene, linalool, and alpha-pinene. So far I have only experimented with smelling the different terpenes.

Myrcene seems to have the most pronounced effects of the four - two inhales over the open bottle and almost instantly I become twice as stoned. The enhanced effect lasts for 10 or 15 minutes. This only occurs when I already have cannabis in my system. When I am sober, the myrcene has no effects aside from smelling nice.

Alpha-pinene seems to bring some clarity to the experience when inhaled. Interesting since it is often found in piney sativas.

Here's an article that gives an overview of the most common terpenes.

Here's a good overview of the different cannabinoids and terpenes in cannabis with detailed explanations and data.

Very interesting arcologist. Please keep up the good work. Besides CBD, do you know if any terpenes have any effect on muscle relaxation and/or pain relief?
