why would marijuana cause a person to passout or black out for a few seconds more than one time?

It was probably laced.  You gotta be real careful with that crap.   Know what you're smoking.  I would try it again as long as you know its safe.

I would call it "a temporary visual disturbance, resulting from postural hypotension", but I am not sure if they have a regular name.\n\n(When it happens to me, I actually informally call it a "brown - out"; just like when there is a slight change in power supply to a room, that does not cause a "blackout".)

He is not high, he is intoxicated with a drug...  Very different angle...  Being "high" denotes something positive; smoking Marijuana is a negative, hence, he is only intoxicated...

If you are passing out you MUST SEE a doctor.\n\nThis is not normal, nor is it safe.

Sounds like the cocaine triggered a panic disorder. I get mild cases of these if i smoke weed sometimes. Takes a couple days for me to recover. Time should help. Continue with the meds and maybe take up meditation. Good luck man, I wouldn't wish panic disorder on my worst enemy.

yeah. go slow. be extra careful, and you should be fine. and for the first idiot who answered, it is very very different from driving drunk. the statistics that say that thousands of car crashes per year are because of marijuana arent true. the tests they use only determine if the driver had smoked marijuana in the last month. there is no way to tell if they are high on the spot, unless they admit it. which very few do.\n\npeace

Yes, but not for long. The person will pass out after a couple of breaths because of hyperoxia (too much oxygen in blood) and subsequent alkalosis (elevation of blood pH because of loss of CO2). You can achieve a similar effect by hyperventilating: taking fast and deep breaths for a minute or two - you will become dizzy and will faint if you don't stop (do NOT do it! ;)).\nBTW, oxygen tanks used as breathing aids are not 100% oxygen, far from that.

I think it is commonly reported to remain detectable for 30 days;  from:  http://www.craigmedical.com/drug_test_faq.htm\nTHC (marijuana): Tetrahydrocannibinol (THC) is an active component in marijuana. Marijuana, a hallucinogen, is commonly ingested by smoking, but it may also be eaten. Marijuana may impair learning and coordination abilities. Marijuana is most commonly the drug of choice among teenagers and young adults. The hallucinogenic effect of Marijuana can lead to irrational behavior, disorientation, and paranoia. Low concentrations of THC persists in urine at a detectable concentration for many days after smoking. Marijuana is the most common recreational drug of abuse.\n\nflush?:  http://www.passyourdrugtest.com/

Syncope is the medical term for "passing out" or "fainting". I assume this could be related to that word.

People who use drugs experience a wide array of physical effects other than those expected. The excitement of a cocaine high, for instance, is followed by a “crash” : a period of anxiety, fatigue, depression, and an acute desire for more cocaine to alleviate the feelings of the crash. Marijuana and alcohol interfere with motor control and are factors in many automobile accidents. Users of marijuana and hallucinogenic drugs may experience flashbacks, unwanted recurrences of the drug's effects weeks or months after use. Sudden abstinence from certain drugs results in withdrawal symptoms. For example, heroin withdrawal can cause vomiting, muscle cramps, convulsions, and delirium. With the continued use of a physically addictive drug, tolerance develops; i.e., constantly increasing amounts of the drug are needed to duplicate the initial effect.\n\n\nBecause the purity and dosage of illegal drugs are uncontrolled, drug overdose is a constant risk. There are over 10,000 deaths directly attributable to drug use in the United States every year; the substances most frequently involved are cocaine, heroin, and morphine, often combined with alcohol or other drugs. Many drug users engage in criminal activity, such as burglary and prostitution, to raise the money to buy drugs, and some drugs, especially alcohol, are associated with violent behavior.

Good question. You need to find out quickly.\nThere are many causes of black outs or syncopal attacks. \n\nThe most common is a vaso-vagal attack which is induced by stress or fear among others. This is the usual fainting episode most people would have witnessed.\n\nFainting or blackouts can also be associated with urinating, pressure on the neck from clothing etc, some heart problems and it could also be the result of prolonged standing. Soldiers sometimes suffer from this on parade grounds.\n\nThere are a few other causes but the best answer in the light of the above is to see your doctor because he is equipped to find out why and show you what you could do about it.

while marijuana may increase focus in some people i would say unless you were physically handicapped EXERCISE like just plain brisk walking or swimming, more blood movement equals more brain blood too

no it is a muscle relaxant which could explain the need for the loo your friend may have needed to go and not have realised it and the weed just helped it along by making them more relaxed. happy smokin

That drug causes paranoia. When I used to do it, I would see and hear things that were not there, partially because I would be worried about getting caught, you always think the cops are right around the corner. If you've been up a few days, maybe you are suffering from sleep deprivation and are seeing things. If that's the case, please, just go to sleep.

Adrenaline is a powerful stimulant. Nobody passes out from adrenaline, or is allergic to it, as far as I know. Passing out probably was due to anoxia (lack of oxygen) due to the constricted airways that come with a severe allergic reaction. That adrenaline saved your life.
