I have tried most everything back in my day.  The worst trip I had was from Mescaline.  Quite a drug. My story was, I did 2 hits of double domer mesc.  Thought it was pretty cool.  NOT!  I ended up in the hospital, my stomach pumped.  Horrible experience, a tube stuffed down your throat while you are still awake, pumping crap out of your stomach.  My family thinking I was not going to make it.  I don't remember it at all, but when I woke up 3 days latter, my family were all around me, thinking I would die.   No one gave me the "I told you so" because I knew what I did, and how close I came to meeting my maker.  That night I lost my best friend, and I made it. I am still here and he isn't.  End of story.

Cocaine produces a wide range of physiological effects in humans, including the stimulation of a plethora of emotional experiences. When people take cocaine, they become euphoric, highly active (locomotion, tremors, and tics), and more talkative than normal. They experience feelings of extreme power and alertness. This initial high is followed by bouts of severe anxiety, paranoia, and depression, which often lead to addiction. Those who become addicted to the drug often turn the habit into an obsession, so that they devote more, and more of their time and money to acquiring and using the drug. \n\nWithdrawal from cocaine can cause a drastic fall in the level of extracellular dopamine in the nucleus accumbens (Rosetti 1992). This decrease is thought to be caused by an increased secretion of dynorphin, one of the endogenous opioids.\n\nmore information in\nhttp://www.macalester.edu/psychology/whathap/UBNRP/Dopamine/cocaine.html\n\n \n(AP) Chronic cocaine use harms brain circuits that help produce the sense of pleasure, which may help explain why cocaine addicts have a higher rate of depression, a study suggests \nhttp://www.cbsnews.com/stories/2003/01/01/health/main534934.shtml

'shrooms taste nasty and will give you the poopies and LSD can have God knows what in it...just have a beer and call it a night. \n\nYour brain cells will thank you in the morning.

As somebody who has used cannabis regularly for too many years I can say yes, it is possible to see trails and auras when very stoned but I have never experienced anything that lasts past the next morning.  I have never head of any long term damage being done but cannabis does have an effect on the intra-ocular pressure (the pressure of fluid in the eye) hence it being used, illegally, in the treatment of the eye condition glaucoma. \n\nI wouldn’t imagine a mother’s ingestion of LSD would effect her eggs as a woman’s eggs are already made at the time of her birth, unlike sperm which are made daily.  If she took it while pregnant there could be an effect though I suppose, depending on how readily the drug crosses the placenta.\n\nDifferent peoples reactions to cannabis vary quite greatly and people who are highly sensitive can experience a trippier experience.  It obviously also depends on the type and quality of the weed.\n\nI have heard  people experiencing ‘ego loss’ from LSD but not from cannabis.\n\nCheck out www.erowid.com for lots of unbiased drug information and other peoples experiences, you may find some similar souls!

Effects on the Brain\n\nScientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to organs throughout the body, including the brain.\n\nIn the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and influences the activity of those cells. Some brain areas have many cannabinoid receptors; others have few or none. Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement4.\n\nThe short-term effects of marijuana can include problems with memory and learning; distorted perception; difficulty in thinking and problem solving; loss of coordination; and increased heart rate. Research findings for long-term marijuana abuse indicate some changes in the brain similar to those seen after long-term abuse of other major drugs. For example, cannabinoid (THC or synthetic forms of THC) withdrawal in chronically exposed animals leads to an increase in the activation of the stress-response system5 and changes in the activity of nerve cells containing dopamine6. Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.\n\n\nEffects on the Heart\n\nOne study has indicated that an abuser's risk of heart attack more than quadruples in the first hour after smoking marijuana7. The researchers suggest that such an effect might occur from marijuana's effects on blood pressure and heart rate and reduced oxygen-carrying capacity of blood.\n\n\nEffects on the Lungs\n\nA study of 450 individuals found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than nonsmokers8. Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses.\n\nEven infrequent abuse can cause burning and stinging of the mouth and throat, often accompanied by a heavy cough. Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers do, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency to obstructed airways9. Smoking marijuana possibly increases the likelihood of developing cancer of the head or neck. A study comparing 173 cancer patients and 176 healthy individuals produced evidence that marijuana smoking doubled or tripled the risk of these cancers10.\n\nMarijuana abuse also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens9,11. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke12. It also induces high levels of an enzyme that converts certain hydrocarbons into their carcinogenic form—levels that may accelerate the changes that ultimately produce malignant cells13. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which increases the lungs' exposure to carcinogenic smoke. These facts suggest that, puff for puff, smoking marijuana may be more harmful to the lungs than smoking tobacco.\n\n\nOther Health Effects\n\nSome of marijuana's adverse health effects may occur because THC impairs the immune system's ability to fight disease. In laboratory experiments that exposed animal and human cells to THC or other marijuana ingredients, the normal disease-preventing reactions of many of the key types of immune cells were inhibited14. In other studies, mice exposed to THC or related substances were more likely than unexposed mice to develop bacterial infections and tumors15,16.\n\n\nEffects of Heavy Marijuana Use on Learning and Social Behavior\n\nResearch clearly demonstrate

no, in fact to test for lsd they have to do a spinal tap that is the only way to test for lsd it is only found in your spinal fluid. if they do give u adrug test they test for opiates,pot, cokecaine, and any other type of pill!       hope this helps u  ltr

Generally they put a shunt into your head that drains the fluid off the brain.

This answer is that provided to me by a doctor some years ago in regard to migraine headaches. I understand that the broad outlines are still regarded as valid, though details have changed. Tension headaches, and other sorts are likely to have a different origin. However, few are well understood, so there's a lot of speculation from medical folks in addition to folk tale origins. But your question was about vascular effects, so here goes. \n\nThe brain is insensitive to pain. It's possible to cut and slice while a patient is conscious without getting much complaint about pain. The same's true of the intestines. However, the arteries in the brain, and the intestines themselves, scream with pain when they are stretched. Gas bloating is sometimes painful as the intestines stretches like a balloon. \n\nIn the case of migraines, they are often preceeded with any of one or more of several perceptual symptoms. The pattern is usually something like: sensory abberation for a few minutes, followed shortly by blinding stupifying pain for an hour or two. In my case it was 'fortification illusions' -- what I called shimmering gold and silver oak leaves. These seem to be the consequence of nerve starvation in particular areas of the brain (the visual cortex in my case) which leads to misfiring and misfunction of these marginally starving brain cells. It seems that arterial contraction is the cause of the cut off blood supply, though the cause of the arterial contraction spasm is unclear. \n\nThere appear to be alarm circuits in the brain to reverse arterial spasms, and indeed these sensory artifacts in migrains suffers (if caused by such spasms) tend not to last very long. The 'expand that artery!!' signal causes stretching -- quite painful stretching -- in the artery (or ateries) involved and takes a few hours to subside. Ergot derivatives were long been known to be effective against migraine pain, but only if given very soon after the sensory illusion artifact appeared. Since these substances caused arterial relaxation, their use provided a clue to the underlying mechanism. \n\nInterference with brain function by arterial spasms and (over)correction by expand 'em signals are likely to have any of a variety of effects, depending on what parts of the brain become involved. And indeed, migraines are sometimes accompanied by vomiting, by great sensitivity to light and sound, and so on. \n\nThe vasoconstriction / vasodilation explanation accounts for much of the observed sequence in migraines, and this is an arguement in its favor. Continuing work with MRI, CT, and PET scans will likely produce a better and more detailed on in future.

Just a small addition to the answer above: permanent brain damage occurs minutes after the heart stops, but  a  person becomes unconscious long before that (in the matter of seconds).

Sounds like Malpitte (think I got the spelling right).  It a cactus seed that produces halucinations.  I've never used them, but I know that your friend was supposed to puke the seeds up a few minutes after taking them.  Who knows what kind of serious mind damage has been done.

First of WHERE THE HELL did his friend get 10 ML of LSD?\nThe "normal dose" of LSD is about 25–50 micrograms, Which means that 10 ml contains about 1000 doses. [1]\nEven though it is hard to overdose to DEATH on LSD, such a high dose would lead to a collapse and he would not be raping anyone. \n\nSecondly, the rule for involuntary intoxication -- will usually excuse any actions that would not have been committed if the person was not involuntarily intoxicated.\nThe good way to prove this would be for a man to get evidence that he was drunk before a number of times and never hurt anyone. And therefore it was an IMMENSE dose of LSD that make him do it and not alcohol, and thus he is not responsible.[2]

It goes to the brain.  That's why some people are called "shitt for brains" not because they're stupid, they're just constipated.

I know about the God spots in the brain. At first they thought it was only in the temporal lobe, but  now they found a few other spots in the brain. \n\n     I will have to do some research on the God gene. \n\n A group of neuroscientists at the University of California at San Diego has identified a region of the human brain that appears to be linked to thoughts of spiritual matters and prayer. Their findings tentatively suggest that we as a species are genetically programmed to believe in God.\n\nThe researchers came upon these cerebral revelations in the course of studying the brain patterns of certain people with epilepsy. Epileptics who suffer a particular type of seizure are often intensely religious, and are known to report an unusual number of spiritually-oriented visions and obsessions. Measurements of electrical activity in the brains of test subjects indicated a specific neural center in the temporal lobe that flared up at times when the subjects thought about God. This same area was also a common focal point overloaded with electrical discharges during their epileptic seizures.\n\nCould this heretofore unidentified part of the brain -- nicknamed the "God module" -- actually be some sort of physiological seat of religious belief? The scientists who discovered it believe it might be. They have performed a further study comparing epileptic subjects with different groups of non-epileptics -- a random group of average people, as well as individuals who characterized themselves as extremely religious. The electrical brain activity of the subjects was recorded while they were shown a series of words, and the God module zones of the epileptics and the religious group exhibited similar responses to words involving God and faith. No word yet on whether the brains of atheists and agnostics might flatline the monitors, but the parallel results among the strong believers are considered impressive.

Or maybe you have been grown for the machines...and wire fed the illusion of your reality straight into your cerebral cortex... and your LSD trip was just REAL reality trying to break through...wow that would make a great movie...I gotta go call my agent.

Sure can.  I can tell you that LSD was placed on stamps for transfer into prisons.
