Research findings for long-term marijuana use indicate some changes in the brain similar to those seen after long-term use of other major drugs of abuse. 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 system(6) and changes in the activity of nerve cells containing dopamine(7). Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.MJ doesn't have many long term affects... <a href="http://my.webmd.com/content/article/70/80972.htm?lastselectedguid=" target="_blank">http://my.webmd.com/content/article/70/80972.htm?lastselectedguid=</a>Quote: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 nonsmokers(9). Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses.Well no shit, of course SMOKING anything isn't good for your lungs.Quote:Even infrequent use can cause burning and stinging of the mouth and throat, often accompanied by a heavy cough. Smoking marijuana increases the likelihood of developing cancer of the head or neck, and the more marijuana smoked the greater the increase(11). A study comparing 173 cancer patients and 176 healthy individuals produced strong evidence that marijuana smoking doubled or tripled the risk of these cancers.Way to link to a poorly done gov't study  <a href="http://my.webmd.com/content/article/23/1728_57309.htm?lastselectedguid=" target="_blank">http://my.webmd.com/content/article/23/1728_57309.htm?lastselectedguid=</a>Quote:Marijuana use also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens(12, 13). In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke(14).^refer to link above.  Oh, and MJ doesn't cause brain damage (though you didn't use that "study" anyway, here's the link) <a href="http://my.webmd.com/content/article/70/80972.htm?lastselectedguid=" target="_blank">http://my.webmd.com/content/article/70/80972.htm?lastselectedguid=</a>Quote:Some of marijuana’s adverse health effects may occur because THC impairs the immune system’s ability to fight off infectious diseases and cancer. 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 inhibited(16).Never heard this one before... link ?Quote:Students who smoke marijuana get lower grades and are less likely to graduate from high school, compared with their non-smoking peers(24, 25, 26, 27). A study of 129 college students found that, for heavy users of marijuana (those who smoked the drug at least 27 of the preceding 30 days), critical skills related to attention, memory, and learning were significantly impaired even after they had not used the drug for at least 24 hours(28).This study isn't saying MJ makes you have bad grades, but people that smoke may have bad grades... two differant thingsQuote:Depression(19), anxiety(20), and personality disturbances(21) have been associated with marijuana use. Research clearly demonstrates that marijuana has potential to cause problems in daily life or make a person’s existing problems worse. 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.Sure, if you have other problems, drugs aren't for you.Quote:Long-term marijuana use can lead to addiction for some people; that is, they use 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 using the drug. People trying to quit report irritability, sleeplessness, and anxiety(38). They also display increased aggression on psychological tests, peaking approximately one week after the last use of the drug(39).Addictive personalities are a fact.  Many people can be addicted to anything.  But, it's all in their head - in this case //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifQuote:A negative aspect of increased anandamide activity was recently shown by studies done by scientists at the University at Buffalo in New York. It has been known for thirty years that very heavy marijuana smoking has drastic effects on sperm production within the testis. The study showed that human sperm contains receptors for cannabinoids. For the first time, a study showed that cannabinoids can affect three key fertilization processes: 1) Prevention of sperm binding to the egg cover, or zona, 2) Regulation of very active sperm swimming patterns, called hyperactivation, and 3) Inhibition of the acrosomal reaction, the normal release of the sperm enzymes that enable sperm to penetrate the egg. These new findings suggest that the anandamides and THC in marijuana smoke may affect sperm functions required for fertilization in the female reproductive tract.Yup, THC and sperm don't mix well.</blockquote>
