dragonrider said:yes, but cannabis causes a surge in dopamine levels. It's that euphoric feeling when you feel the cannabis hitting your brain. Harmala's will prevent the breakdown of dopamine, so they elevate dopamine levels as well. So i argue that at least one part of the cannabis experience IS amplified. The dopaminergic dimension of cannabis.Psybin said:UgraKarma said:If we're speaking about harmalas increases in the neurotransmitters that are also related to the high achieved through smoking cannabis - I'd argue they might have some potentiation relationship without being a direct agonist of any type.
Being an agonist is irrelevant as we're talking about potentiation, not agonism. Harmalas do not modulate levels of cannabinoids in the brain and thus do NOT potentiate cannabinoids.
What you describe is not potentiation of cannabis but rather synergy. The dopamine release is actually a result of downstream modulation of GABA receptors, which modulate synaptic dopamine. Harmalas retard/prevent the breakdown of this dopamine, but that is not the same as potentiating THC, which would consist of THC accumulating in the synapse, which is the opposite of what happens.
In any case, harmalas don't even increase DA in the synapse the way you think. Check out this thread if you don't believe me. The paper describes harmalas as causing efflux of dopamine from the synapse, which is opposite of what you've suggested (that harmalas increase synaptic DA to potentiate cannabis).
These data suggest that harmine augments DA efflux via a novel, shell-specific, presynaptic 5-HT2A receptor-dependent mechanism, independent of MAOI activity
Think about: why would researchers be investigating harmalas to treat Parkinson's if it increased synaptic DA? Parkinson's patients have to much synaptic DA floating around, which is why researchers are looking to harmalas as a way to remove excess DA from the synapse.
An example of actual potentiation would be something like diphenhydramine and morphine, or taking a SRI with a SERT releasing agent.
