You sound like you're an anti-drugs aficionado and here to preach the evils of drugs to us all?
That's not my intention. I see this discussion as being analogous to people who drink discussing hangover cures. There's nothing wrong with taking drugs, all drugs have side effects, it makes sense to understand how and why these side effects happen as well as having strategies to counter them. I'm pro-drug, I'm just trying to learn how to be more responsible with my usage.
Produced Raw, when was the last time you smoked bud with significant amounts of THC and no other cannabinoid? Seriously, tell me!
Never. Maybe if you smoked less you'd be able to respond to things I actually said.
After doing some more 'xperimenting and reading, I strongly suspect that there is an interaction between caffeine and cannabis, particularly between sativa's and caffeine and even more particularly between sativa's and coffee. I also suspect that there is interaction between opioids and cannabis.
Cannabidiol exerts it's anxiolytic effect by agonising adenosine receptors (
http://webcache.googleusercontent.c...proves-cognition/+&cd=5&hl=en&ct=clnk&gl=uk):
Erica Carrier and co-workers at the Medical College of Wisconsin, Milwaukee, determined that CBD exerts its anti-anxiety effects by activating the adenosine receptors
Caffeine does the exact opposite by antagonising adenosine receptors, and competitively too (
http://circ.ahajournals.org/content/99/19/2499.full):
Caffeine acts mainly via blockade of adenosine receptors
In other words, combining a Sativa with caffeine results in the blockade of Cannabidiol's anxiolytic and, I assume, anti-psychotic effect. High doses of caffeine in isolation can also induce psychosis (
http://www.ncbi.nlm.nih.gov/pubmed/19407709):
As a competitive adenosine antagonist, caffeine affects dopamine transmission and has been reported to worsen psychosis in people with schizophrenia and to cause psychosis in otherwise healthy people
There is a further addition to this in that caffeine increases Cortisol levels (
http://www.ncbi.nlm.nih.gov/pubmed/16631247):
Caffeine elevates cortisol secretion
Which in turn raises dopamine levels (
http://www.jneurosci.org/content/24/11/2825):
...consistent with a facilitating effect of cortisol on dopamine neuron firing
It's pretty clear that psychosis is a function of high dopamine levels with a lack of counter balance. Coffee does something differently to caffeine alone - it also contains MAOI's which serve to further increase dopamine levels (
http://www.biopsychiatry.com/coffee-maoi.htm):
coffee contains compounds acting as MAO inhibitors
So there is a strong interaction between caffeine and sativa's. What about opioids?
Morphine appears to induce hypersensitivity in NA and DA receptors, unless taken chronically, where it does the exact opposite (
http://www.ncbi.nlm.nih.gov/pubmed/12119450):
hyperactivity, reverse tolerance and postsynaptic dopamine receptor supersensitivity induced by morphine
This, and my personal experience, suggests that chippers are more likely to experience psychotic symptoms from Sativa strains than opioid-naive people. It also suggests that junkies are less likely to experience Cannabis-induced psychosis, until they withdraw, I guess.
Another interesting question is why do so many people smoke weed half their lives then suddenly develop anxiety from it? From the paper above, we can see that GABA has a substantial effect on calming down those DA receptors. Most people in our society drink. Alcohol has a strong effect on GABA. A strong effect produces tolerance which reduces the effect of GABA which then reduces the inhibition of Dopamine and ends up making one more likely to experience cannabis-induced psychosis.
but in most cases it is cured by smocking some more charas
This is an interesting point. Perhaps if the psychosis is brought on by excessive dopamine and smoking yet more releases yet more dopamine, the body adapts and downregulates DA receptors and the problem is solved?
So that's four more counters to this problem. Stop consuming caffeine, drink less, smoke more and stop chipping or make the jump and become a heroin fiend.
