Are magic mushrooms synergistic with cannabis and your ECS
Sometimes depression can hurt, literally. Interestingly, this has a lot to do with our Endocannabinoid Systems (ECS) – a network that consists of a few receptors and two neurotransmitters. Pain and emotions are tied together through these messengers. And, it is through the ECS that magic mushrooms and cannabis can bind into a synergistic therapeutic, or a counterintuitive mistake. (1)
This infographic details different serotonin receptors and their effects. The ECS and serotonin (5-HT) bind at many receptors, but the focal point of magic mushrooms is 5-HT2a. (2, 3) Other receptors might be the cause of side effects like nausea, though. Photo courtesy of Maroteaux et al 2016.
How does psilocybin alter the ECS?
Happiness can boost your endocannabinoid system, according to a few scientific studies throughout the past two decades. (1, 4-6) This is because a receptor that expresses with the happy-messenger – serotonin – can also help release natural cannabinoids in your body. Also, a special form of serotonin acts as a nonintoxicating but still full agonist towards the cannabinoid 1 (CB1) receptor. (1) This means that a better mood can prevent cancer and other ailments – through our bodies’ own cannabinoids. And, there is a blissful feedback loop that occurs between serotonin and the ECS. After all, our endocannabinoids will boost serotonin and vice versa – the two systems crosstalk. (5)
Anandamide and serotonin go hand in hand in mental health therapeutics.
Serotonin and mushrooms a deeper synergy
The intoxicant in therapeutic mushrooms, psilocin, and its prodrug, psilocybin, is similar to serotonin. (1, 2) Therefore, psilocin will bind to a similar receptor as serotonin, namely 5-HT2a. In fact, this is one of the primary effects of magic mushrooms that has seen the attention of researchers.
5-HT2a is what binds magic mushrooms and cannabis into an intricate synergy given the receptor also helps release ECS messengers and their derivatives. In summary, serotonin will agonize an endocannabinoid that is crucial for everyday survival. But, psilocin flips this function and instead promotes non-associated and less important ECS derivatives that benefit therapy. (3, 7)
Serotonin releases the enzyme, PLC, once it docks to the 5-HT2a receptor, which will in turn help release the workhorse endocannabinoid, 2-AG (red path). After psilocin (purple path) occupies the 5-HT2a’s space, the receptor releases PLA2 instead of PLC. Psilocin’s purple path possibly purports profound but unexplored impacts on ECS signalling. This will drop the regular function of 2-AG in the serotonin system and instead focus ECS signalling on psilocin and OEA. This is because PLA2 more strongly expresses with likewise metabolites rather than actual endocannabinoids.
Magic Mushrooms and the ECS – tied by a happy endorphin
Doubling back on the feedback loop and the fact that endocannabinoids boost serotonin – the ECS’s role isn’t exactly straightforward. (1, 4) Endocannabinoid activity can decrease the functionality of the serotonin receptors while still elevating their signalling activity. So, the endocannabinoid system regulates the effects of psilocybin. But, magic mushrooms will alter the endocannabinoid system, forming a synergistic connection. (4-7)
Upon writing this last phrase, this author has concluded – the endocannabinoid system acts as a safety net during a mushroom trip. But, not everyone will experience positive benefits from adding cannabis to psilocybin given a complete shift in the functionality and cross-talk between the ECS and serotonin system.
Psilocin’s key and translocation of ECS-serotonin signalling
Mushrooms will essentially flip serotonin’s role in the endocannabinoid system and drive the CB1 receptor through anandamide-like derivatives. Whereas, serotonin normally facilitates a unique relationship with dopamine through CB2 receptors via 2-AG. One highly expressed compound in psilocin’s path is OEA, a major constituent in chocolate. Mushrooms chocolates – anyone?
Side effects can also be balanced with the terpene, caryophyllene.
Conclusively, the effects of magic mushrooms are, in part, facilitated through your ECS and can either be complimented or complicated with cannabis. Unfortunately, though, science is not yet sound on the subject. Parrish et al 2006 did note a massive difference in psilocin’s ability to produce 2-AG through the serotonin (5-HT2a) receptor in mice compared to other 5-HT2a agonists, including 5-MEO-DMT, LSD, and their control – serotonin. Unfortunately, the study did not adopt any conclusions for psilocin’s anomaly. The conclusion was still left incomplete by Maroteaux et al. 2019, and again by Arnold et al. 2021. But now, Health Canada has granted a licensed cannabis research lab permission to study magic mushrooms. So, we might finally get a more detailed answer to these questions soon.

- When serotonin and LSD encourage DAG to metabolize into 2-Ag through a 5-HT2a mechanism, an equal amount of inositol phosphate (IP) is produced. Conversely, ten times as much IP is produced when the 5-HT2a mechanism is activated by psilocin. (4)
- Despite its neglect of the PLC path, psilocin can still activate 2-AG with an affinity similar to serotonin through a mechanism this author has yet to find in the literature.
- Magic mushrooms should alter, not neglect, post-synaptic CB1R signalling. And psilocybin will lead to a flood of IP after metabolism to psilocin.
