Probably proprioceptive fibers from the foot. The first synapse would be in the nucleus gracilis at the brainstem. So about 6 feet for someone pretty tall.

For a blue whale, proprioceptive fibers from the tail would be close to 120 feet, so I would guess that's the longest neuron ever.

Don't appologize and don't change your style. I like it. If, there is something in your posts that I don't fully comprehend, I can use the references you always provide, to educate myself. Thanks.

how do you know this? please post a reference so that I can take a look, if you have one.

In my experience cannabis works better when it is left in the air. Think about the process of curing itself. People dry the cannabis so that it becomes psychoactive. I am under the impression that the oxidising process is what makes cannabis psychoactive!

The stems do not work very well for cleaning your pipe.

This is an observation I made many times in my smoking days. Times may vary from sample to sample, depending on density and so on, but with dry, not-so-dense commercial grade cannabis, even a few days sitting out, particularly in sunlight, can make a big difference. Though not addressing this issue directly, you can find some information on cannabis degradation

As I made clear, I was referring to plants that are already cured. And, AFIK, curing just allows the moisture in the plant to evaporate, making it combustible, and preventing the growth of mold on the plant once its stored, rather than actually increasing the psychoactive content.

Well, one of the things oxidation does is convert your THC to the nonpsychoactive CBN, cannabinol. As long as your stash is subject to oxygen, this is happening. Think of it as a very slow burn. This is a major reason why cannabis loses its potency over time.

Yes. It absolutely can not help you with your diet (unless you're diet consists of brownies, in which case it helps quite a bit).

we'll have to agree to disagree here. According to yourself, it loses most of its potency after a few days. I've owned some very dry flowerheads before, kept them in a bag the whole summer, and the high was always as fresh. (aside from the part where I became immune to smoking it neat and had to have a weeks break)

A guy I 'knew' had MS and used cannabis to keep his nerves working good. He sold me some 'top of the plant' material. It was well cured, but still slightly soft. after a couple of weeks it was solid with sap, almost as though it were glazed. If I squeezed a bit between my fingers It would shatter. Very dusty, and very potent. Now, Thai Grass, which is commercially available in Amsterdam resembles what we call 'bush' over here- so called because it is brown and possibly very old. Since THC degrades and turns into cannabidiol over time, this is going to mean that the smoke is a 'heavier hit'. Thai grass, from most Bulldog coffeeshops in the Dam, is quite heavy.

Now, I'm having trouble working out what you mean by 'commercially available' since commercially available in Amsterdam means- it's there to buy in many flavours and strengths. It is never, apart from bottom of the plant joint filler, 'low-density cannabis'. This stuff, I recall tends to be very light, low in sap, and not very frosty. To be blunt, its shit to start with, and if it were commercially available here, I wouldn't get it.

As far as I feel, when I tried uncured cannabis, it didn't work. This has to be because the cannabis is non-psychoactive when wet.

Perhaps with very dense, sticky flowers, when cured (the way it should be) air can't get to the inside of the bud, leaving the THC intact?

EDITED TO ADD:
this point bothers me. I don't know whether it was a feeling based observation or one based upon scientific knowledge, but I dare not suggest that ps418 is using 'hazy' memories and juvenile logic to conclude that sunlight destroys thc. You see, in the flowering stage of a cannabis plants development, a cultivator will use high pressure sodium bulbs to simulate the autumn sun. Something in the properties of this light (I don't know why) causes the cannabis plant to produce psychoactive elements. So why it would be that real sunlight, possibly with a different spectrum of light, destroys THC evades me???

ps418

Disagree all you want, but you're not disagreeing with what I actually wrote. I said letting a small piece of cannabis "sit out for a few days," NOT keeping them in a bag. As far as the loss being "most" or "some," as I said this depends on things like the density of the cannabis. To be more precise, let me change most to "a significant amount."


Fair point. By commercial I mean the vast majority of pot in the US, which is fairly low-grade sativa, mostly grown in Mexico, certainly not like what you find in Amsterdam.


No, its a simple fact based on my own observation. Its also supported by the references I gave, as well as by cannabis botany manuals. That you think this at all controversial is odd.

Fairbairn JW, Liebmann JA, Rowan MG
J Pharm Pharmacol 1976 Jan;28(1):1-7

And by chapter 4 of Marijuana Botany, by by Robert Connell Clarke, which states that:


Gosh, I was unaware that plants need sunlight to grow! One difference you are overlooking is that before you harvest the plant, the plant is alive and actively synthesizing cannabinoids, while after harvest, the plant is dead, and active synthesis of new cannabinoids ceases. Does this distinction evade you too?

I acknowledged that you took flower density into account. I questioned the conditions. If the small piece of cannabis was in the sun then the sunlight, according to the interesting study you referred me to, was a primary factor in the fast decline in THC and not the air. Hence the confusion (I should have said I kept it a brown paper bag)

but surely you can't extrpolate your own experiences of buying pot in your own environment to the entire United States? unless..? I'll dare bet there is plenty of good pot in north america. Did you ever get any decent stuff? If so, please give me a description.

given my ignorance between the recently elucidated 'dead' cannabis and synthesis 'on the plant', the controversy should be understandable. however, I am simply interested in learning, so I will tolerate what you overlooked.

my point was that sodium bulbs are used to aid the growth of flowers on the cannabis plant. Without these the cannabis isn't as strong. I assumed that the light was key in synthesising thc. I know how to grow good cannabis, but I don't know why thc is synthesised, or how to maximise thc synthesis. I shall have to find out. I apologise for not thinking deeply enough.

thanks for the botany link too.

I WROTE:

and from the botany link:

so... 2 points. sythesis DOES take place after the flower has been picked, but not the synthesis of new thc??, although this is suspected. And curing, accordingto the study, makes the flowers psychoactive. Unless this guy is wrong, of course.
