Guest guest Posted May 22, 2009 Report Share Posted May 22, 2009 Hello folks. When taking the marjuana herb internally daily, is there a concern about gradually increasing dependency (maybe by gradually decreasing the brain's ability to create/release dopamine?), and can this result in depression and even suicidal tendencies, as well as the other symptoms listed in this article (below)? Hmm, how about when using it externally (topically) on a daily basis? Thank you. peace and healing, Glen from Illinois, USA ---------------------------------------------------------------------------- ----------------- _http://www.scienceclarified.com/Io-Ma/Marijuana.html_ (http://www.scienceclarified.com/Io-Ma/Marijuana.html) << The effects of marijuana on a user change dramatically as the dosage increases. Taken at low doses, marijuana tends to make a user drowsy and relaxed. The user may also feel a general sense of well-being. As the dose increases, a user may experience an altered sense of time and awareness, and may have difficulty completing thoughts and taking part in conversation. A user's sense of balance and short-term memory (remembering very recent events or from one moment to the next) may also be affected. At higher doses, severe psychological disturbances can take place, such as paranoia, hallucinations, and panic attacks. Marijuana affects the cardiovascular system by increasing heart rate and dilating (expanding) blood vessels in the eyes. Difficulty in coordinating body movements and pains in the chest may be other effects of the drug. Scientists believe that long-term use of marijuana damages the lungs in a manner similar to tobacco smoking. Scientific studies released in mid-1997 indicate that people who smoke large amounts of marijuana may experience changes in their brain chemistry. These changes are similar to those seen in the brains of people who abuse addictive drugs such as heroin, cocaine, nicotine, and alcohol. All addictive drugs increase the amount of dopamine in the brain. Dopamine is a brain chemical responsible for causing feelings of reward. The new studies found (for the first time) that high doses of marijuana increased the levels of dopamine in the brain. Constant use of addictive drugs, however, can cause the brain to lose its ability to produce high levels of dopamine. When this happens, a drug user feels a greater need for the drug, or for even stronger drugs. Scientists believe this may occur with marijuana. Users of addictive drugs feel withdrawal symptoms (feeling anxious, edgy, and unable to cope) when they stop taking the drugs. It was previously believed that marijuana users did not suffer feelings of withdrawal. However, the recent studies indicate that heavy users of marijuana smoke not so much for the " high " but to calm their feelings of anxiety brought on by withdrawal from the drug. Since THC is absorbed primarily in the fat tissues and lingers in the bloodstream, withdrawal symptoms are not as evident as with fast-acting drugs like nicotine. >> **************Kick start your favorite grad’s career with mobile email for under $50.
