how long does weed stay in your system???

what a world. something natural that comes out of the ground, and we can't touch it. why the hell can't you smoke a natural plant, something that comes out of the ground? jesus, you know what's not natural? we've got pills to make an 80-year-old man hard, but we can't smoke pot. dedicating all our natural resources to keeps old pricks erect, but we're putting people in jail for smoking something that grows in the dirt? ahhh hell i'm all over the place.

 

and as many people felt certain races shouldn't be allowed to inbibe of such substances, racism helped further the loss of our rights. oh, glory be

 

I used to use heavily as a young fella and I was on probation typically with urine testing on a monthly basis. Cocaine (my previous weakness), I could use 24 hours before a test and piss clean. I have heard chemicals like coke, heroin, etc. don't appear in your system after intoxication is complete. That would put coke at roughly 15-20 minutes for detection, and heroin less than 30 minutes if smoked, 10 minutes if popped. LSD is not even detectable when you are tripping. I went to my probie once while I was on bomb and took a piss test.

I always heard pot was detectable in 30 days or less. I also was told by an old druggie that high concentrations of citric acid cleaned you out. Vineger is acid, so I guess it works just as well (which is the rumor). I would usually stop burning 2 days before my tests and chow down on the frozen concentrated orange juice can like a slushy. It was strong, but not unpleasant. I'd do that the day before a test and never got busted.

I tested every month for 4 years, all the while I sold/smoked pot and was nastily addicted to coke (I usually freebased) and ate acid like it was candy. Durring that time I did everything, and I mean everything (well some designer drugs out there nowadays didn't exist then). I never got caught. So from personal experiance, 2 days clean from buds and eating a frozen OJ concentrate the day before gets you by.

 

Yeah, you just have to bite the bullet and not smoke. Hopefully they won't test you year-round, and you can get some tokes in for the offseason. Marijuana doesn't help you play football. That sucks. Amphetamines, steroids, human growth hormone... that sounds right.

 

smoke ye weed as ye lungs after a while will look like this..
lung cancer

ye say i will stop b-4 i get cancer..keep dreaming

 

Those lungs are from cigarettes.

 

pollution
WOW
ye mean smoking weed EVERY DAY ..ye are immune from CANCER of the lungs..YE MUST HAVE THE MIRACLE WEED............

 

It does not cause cancer.

Marijuana and Cancer

Consider these facts before you decide to smoke pot.

There are more cancer-causing agents in marijuana than in any other substance presently known to man. Crude marijuana contains more carcinogens (one hundred fifty more) and in greater concentration than tobacco.

One joint deposits four times as much cancer-causing tars in the smoker's airways as does tobacco smoke. Smoking three to five joints a week is equal in harmful effects to smoking 16 cigarettes daily. Smoking one joint a day is equal to a pack of cigarettes daily. Three joints smoked per week for three to six months carries the same probability of developing lung cancer as smoking a pack of cigarettes daily for 20 to 30 years.

Because the pot smoker tends to breathe in the smoke more deeply and hold it longer than the tobacco user, greater harm is done to the lungs. Five times as much carbon monoxide (associated with coronary diseases) is inhaled in marijuana smoke as in tobacco smoke.

Prolonged exposure to marijuana smoke can cause emphysema-like symptoms, cancer of the lungs, mouth, and tongue, and leukemia in children born from marijuana-smoking mothers.

Cases of cancer reported in users in their 20's and 30's include cancer of the mouth, jaw, tongue, larynx, head, neck, and lungs. Normally these cancers would occur between the ages of 55 and 60.

The American Cancer Society, the Food and Drug Administration, and the American Medical Association have all stated that marijuana has not been shown to be safe or effective as a medicine. Smoked marijuana has not been shown to be superior to other available therapies for the treatment of nausea and vomiting associated with cancer chemotherapy.

Still think marijuana is a harmless drug?


Effects on the Brain

Scientists 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.

In 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.

The 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.
Effects on the Heart

One study has indicated that a user'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.
Effects on the Lungs

A 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.

Even 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.

Marijuana 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.
Other Health Effects

Some 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.
Effects of Heavy Marijuana Use on Learning and Social Behavior

Research clearly demonstrates that marijuana has the potential to cause problems in daily life or make a person's existing problems worse. Depression17, anxiety17, and personality disturbances18 have been associated with chronic marijuana use. Because marijuana compromises the ability to learn and remember information, the more a person uses marijuana the more he or she is likely to fall behind in accumulating intellectual, job, or social skills. Moreover, research has shown that marijuana’s adverse impact on memory and learning can last for days or weeks after the acute effects of the drug wear off19,20,25.

Students who smoke marijuana get lower grades and are less likely to graduate from high school, compared with their nonsmoking peers21,22,23,24. A study of 129 college students found that, among those who smoked the drug at least 27 of the 30 days prior to being surveyed, critical skills related to attention, memory, and learning were significantly impaired, even after the students had not taken the drug for at least 24 hours20. These "heavy" marijuana abusers had more trouble sustaining and shifting their attention and in registering, organizing, and using information than did the study participants who had abused marijuana no more than 3 of the previous 30 days. As a result, someone who smokes marijuana every day may be functioning at a reduced intellectual level all of the time.

More recently, the same researchers showed that the ability of a group of long-term heavy marijuana abusers to recall words from a list remained impaired for a week after quitting, but returned to normal within 4 weeks25. Thus, some cognitive abilities may be restored in individuals who quit smoking marijuana, even after long-term heavy use.

Workers who smoke marijuana are more likely than their coworkers to have problems on the job. Several studies associate workers' marijuana smoking with increased absences, tardiness, accidents, workers' compensation claims, and job turnover. A study among postal workers found that employees who tested positive for marijuana on a pre-employment urine drug test had 55 percent more industrial accidents, 85 percent more injuries, and a 75-percent increase in absenteeism compared with those who tested negative for marijuana use26. In another study, heavy marijuana abusers reported that the drug impaired several important measures of life achievement including cognitive abilities, career status, social life, and physical and mental health27.
Effects on Pregnancy

Research has shown that some babies born to women who abused marijuana during their pregnancies display altered responses to visual stimuli28, increased tremulousness, and a high-pitched cry, which may indicate neurological problems in development29. During the preschool years, marijuana-exposed children have been observed to perform tasks involving sustained attention and memory more poorly than nonexposed children do30,31. In the school years, these children are more likely to exhibit deficits in problem-solving skills, memory, and the ability to remain attentive30.
Addictive Potential

Long-term marijuana abuse can lead to addiction for some people; that is, they abuse the drug compulsively even though it interferes with family, school, work, and recreational activities. Drug craving and withdrawal symptoms can make it hard for long-term marijuana smokers to stop abusing the drug. People trying to quit report irritability, sleeplessness, and anxiety32. They also display increased aggression on psychological tests, peaking approximately one week after the last use of the drug33.

Still think marijuana is a harmless drug?

 

According to editors of the prestigious Lancet British medical journal: "The smoking of cannabis, even long-term, is not harmful to health. ... It would be reasonable to judge cannabis as less of a threat ... than alcohol or tobacco."
REFERENCE: Deglamorising Cannabis. 1995. The Lancet 346: 1241. Editorial. November 14, 1998. The Lancet.

According to a 1999 federally commissioned report by the National Academy of Sciences Institute of Medicine (IOM), "Except for the harms associated with smoking, the adverse effects of marijuana use are within the range tolerated for other medications."
REFERENCE: National Academy of Sciences, Institute of Medicine (IOM). 1999. Marijuana and Medicine: Assessing the Science Base. National Academy Press: Washington, DC, 5.

 

your second reference hurts you as much as it supports you, ash. it still lists the dangers of smoking as unnacceptable. as for the first: the study results announcing that marijuana has harmful effects on the body overwhelmingly outnumber the amount of studies claiming the results are nill. personally, i don't care, but it [bold]is[/bold] worse on you than cigarettes and such.
