    about cottonmouth, i think it's just because some of your body systems slow down due to weeds effects on the CNS (this i absolutely pulled out of my ass, someone correct me please if it's wrong lol)

    Marijuana is a vasodilator which causes the blood vessels in your eyes to dilate. This basically means the blood vessels open up and become larger. I believe the red eyes are caused by being able to see so many more vessels that used to be too small to notice before smoking. The dilation is caused by the action of THC which causes the smooth muscle lining blood vessels to relax. Hope that helps

    Edit: yes, dry mouth is most likely caused by stimulation of the sympathetic nervous system. This is a division of the autonomic nervous system that reacts in times of stress normally, but is artificially stimulated by the THC. You can feel your sympathetic nervous system kick in when you start to run or are scared (notice sweating, dilated pupils, etc.). One of the other things is your body stops producing so much saliva... hence dry mouth

    It certainly can be, just as many other drugs such as alcohol, caffeine, and cocaine, especially if used in inappropriate ways. Below are some of the wikipedia listed effects...

    Anti-emetic properties Modulation of working and short-term memory Impairment of short-term memory Enhancement of many other drug effects (including those of alcohol, ecstasy, tobacco, heroin, cocaine) Auditory or visual hallucinations at high doses in some users Paramnesia, repetitiveness and ambiguation Increased appetite (often referred to as "the munchies"), an effect of stimulation of the endocannabinoid system, which affects body weight, insulin resistance, and dyslipidemia. Increased sexual pleasure Increased awareness of sensation Increased awareness of patterns and colors Increased appreciation of music Increased mental activity, like metacognition Induced sense of novelty Initial wakefulness followed by drowsiness and lassitude ('burnt out') Introspective or meditative states of mind Gain or loss of some inhibitions Mild euphoria, feelings of general well-being Relaxation or stress reduction Mild tachycardia (Increased heart rate) Mild, temporary dry mouth (sometimes referred to as cottonmouth, pasties, or the drys (NZ)) Mild, temporary keratoconjunctivitis sicca (sometimes referred to as blood-shot eyes, dry eyes or red eye(UK)) Mild paranoia and anxiety
    Most of all: it is best for the world’s number-one killer - stress. It can safely curtail or replace Valium, Librium, alcohol, or even Prozac, for millions of Americans.

    While cannabis intoxication varies with psychological set and social setting, “the most common response is a calm, mildly euphoric state in which time slows and a sensitivity to sights, sounds and touch is enhanced.”

    In contrast to marijuana’s safe, therapeutic action, benzodiazephines (Valium) abuse is the number-one drug abuse problem in the country, and is responsible for more emergency room admissions in the United States than either cocaine-related problems or morphine and heroin-related admissions combined.

    While tobacco constricts arteries, cannabis dilates (opens) them. Because migraine headaches are the result of artery spasms combined with over-relaxation of veins, the vascular changes cannabis causes in the covering of the brain (the meninges) usually made migraines disappear.

    Evidence of vascular change caused by cannabis can be seen in the user’s red eyes, which are extensions of the brain. However, unlike most other drugs, cannabis has no apparent effect on the vascular system in general, except for a slight increased heart rate during the onset of the high.
    No website i could find actually gives a proper scientific explanation why, interesting because i dont know the actual reason myself but i would assume its simple because weed, THC trichs have chemicals in them which dehydrate you and make you have less saliva and less water around your eyes and mouth and whole body in general.

    im pretty sure that red eye is caused by the smoke irretating your eyes(like how sand in your eye would make it red) thats why your eyes get way more red when your boxing it or something cause there is smoke all around you.

    now for really really bloodshot eyes i dont think thats the case.
    then for dry/cotton mouth that is because there is all kinds of smoke in your mouth it just drys it out.
    and cotton mouth is caused by the dry mouth since you have no spit...

    Yes Ive noticed this as well, regardless of any other medical reasoning. It doesnt matter how much weed I smoke... my eyes only get red when I cough. I made the connection when I saw my friend had a popped blood vessel in his eye, when I asked him what it was from he said it was from straining too hard when takin a dump. The next time I smoked and started coughing like shit I felt that same kind of strain, and I began feeling how much my eyeballs were strained. And sho nuff my eyes were bloodshot as hell. Ive even done tests over a lengthened period of time, coughing more or less extraneously and seeing if the resulting redness of my eyes was analogous.. and it was. So even if I smoke like half an ounce of some danky dank in a few hours, as long as I dont cough, my eyes arent red. Sleepy lookin, maybe.. lol.. but not red.

    I get terrible red-eye, a spliff to myself and my eye's go extremely red. I don't even have to be that stoned. But i use Eye Brightener eye drops which sort me out. if i put them in, people just think i'm a bit tired rather than stoned (apparently my face goes a bit "droopy" when stoned.) Some red-eye will be because smoke getting in, but you can tell when you get smoke in your eyes because it's quite irritable in my experiences.

    as for drymouth, i only get it if i think about it. if someone mentions it, i'll get it, but if not, i don't. I dont think it's dehydration really because that implies all you're body to be dehydrated. For me, i want a drink just to wet my mouth again, not to rehydrate. There's definately a difference between "i want a drink cz im really dehydrated and not had a drink in a while" and "i want a drink because i got dry mouth"

    i hope that all made sense, it didn't make much sense to me and i wrote it and i'm not even stoned, what's with that? lol

    It all made sense, but Ive noticed that when I smoke, a good majority of the hydration in my body immediately proceeds to my bladder. Seriously, every time I smoke, I gotta piss real bad at least once or twice within 20 minutes of smoking, and my body is more dehydrated.. and the dehydration of my body is something that took me many years and some QiGong meditation to be able to become aware of. Other than being thirsty, having headaches, dry lips, and yellow urine.. the usual signs.

    I dont get red eyes when I have my contacts in. If they are out, I get red eye like no other.

    I use RotoV Ice eye drops to clear up redeye though. That stuff turns your eyes pure white after it starts working, not a sign of redness anywhere.
