The reason why these synths can kill someone while you can literally never die on weed it is because most synths (with a few exceptions) are fully (potent) agonists of the cb1 receptor but thc is a partial agonist of those receptors, it is very much as Kratom been a partial agonist of opioids receptor while heroin is a full agonist…
I have found some synths to act as a partial agonist: JWH-073 (now forbidden) and EG-018 (really hard to get)
are the ones that come to my mind.
As you are pointing I think that mix it with an adequate quantity of cbd (something that for some strange reason nobody has been doing) is very important as cbd could compete for the cb1 and cb2 space on the receptors don’t allowing to the synths to a full agonist action…
It has been tested that even thc prevents against synth overdose as thc competes within the same receptors…
Things as a mixture of cbg cbn and cbd come to my mind as an interesting way of minorate the risk with those very wild substances…
Bear in mind that even thc alone (Marinol) has been shown with the potential to produce seizures in large doses, CURIOUSLY enough, seizures. A thing so frequently attributed to synth cannabinoids and an illness for which curiously enough full spectrums are so wonderful.
Seizures, probably an illness closely related to the cannabinoid system…
What I mean with the Marinol thing is that cbd, terpenes, and the rest of cannabinoids are very important for the weed lack of side effects as well.
If you could make a hash with a synth that guarantees the life of people and give them a more enjoyable high than weed , you are a king, unfortunately, this hash is sold most of the time as real hash (aka faking hash) which is very dangerous and no one deserves that.
