Cocaine Addiction and the Brain

September 25th, 2009 · No Comments

Approximately 2 million Americans currently use cocaine because of the temporary euphoria effect it provides. Unfortunately this has contributed to making it one of the most dangerous and addictive drugs in the country. Cocaine addiction is known to cause severe biological and behavioral problems that may or may NOT be changed!

Researchers at the University of Missouri in the Dept of Electrical and Computer Engineering are utilizing computational models to study how the brain’s chemicals and the connections between neurons react to cocaine addiction. The findings could have an effect on future drug treatment.

Cocaine addicts get such a strong connection in the brain from the decision-making center to the pleasure center that it simply makes the addict keep seeking the use of cocaine.

Marijuana Damages DNA

June 16th, 2009 · No Comments

Researchers from the Cancer Biomarkers and Prevention Group, Department of Cancer Studies and Molecular Medicine and Karolinska Institute, Sweden, are reporting “convincing evidence” that marijuana smoke damages the genetic material DNA in ways that could increase the risk of cancer.

Marijuana (Cannabis) smoke contains 400 chemical compounds including 60 cannabinoids. Because of its lower combustibility than tobacco, it contains 50% more carcinogenic polycyclic aromatic hydrocarbons including naphthalene, benzanthracene, and benzopyrene, than tobacco smoke.”

“The smoking of 3-4 marijuana cigarettes a day is associated with the same degree of damage to bronchial mucus membranes as 20 or more tobacco cigarettes a day,” the researchers state.

Marijuana and Dangerous Driving

March 15th, 2009 · No Comments

In a recent report in the journal Accident Analysis and Prevention, thrill-seeking young men in their 20’s are more likely to drive under the influence of cannabis (DUIC) and engage in reckless driving,

“We observed that dangerous driving behaviours are interrelated. Individuals scoring high on impulsivity or sensation-seeking scales demonstrated an elevated risk of driving under the influence of marijuana,” states senior author Jacques Bergeron, a professor at the Université de Montréal’s Department of Psychology.

The study also found that men with self-reported DUIC tend to be associated with an increased risk of being involved in a car accident.

Marijuana and Brain Damage

February 10th, 2009 · No Comments

Research appearing in the January 2009 issue of the Journal of Psychiatric Research shows that teenagers who are heavy users of marijuana are more likely than non-users to have disrupted brain development.

Pediatric researchers found abnormalities in areas of the brain that interconnect brain regions involved in memory, attention, decision-making, language and executive functioning skills. The findings are of particular concern because adolescence is a crucial period for brain development and maturation.

Marijuana and Male Fertility

February 1st, 2009 · No Comments

The Biology of Reproduction publication is the official journal of the Society for the Study of Reproduction.

A research report in the February 2009 issue states that human male fertility is impacted by chronic marijuana users. Evidence shows that the sperm has decreased ability to fertilize due to poor penetration of the female egg.

This is more evidence that marijuana is not as safe as some people think.

Marijuana use also affects pregnant women.

Marijuana Use and Pregnancy Failure

December 31st, 2008 · No Comments

A study from Vanderbilt University that appears in the Journal of Clinical Investigation reveals that marijuana use at the time of conception and early in pregnancy prevents embryos’ safe passage from the ovary to the uterus, resulting in early pregnancy failure.

Marijuana, the most widely used illegal drug among women of reproductive age, binds to 2 receptors — cannabinoid receptors 1 and 2 (CB1, CB2) — which are found in the brain and other organs including sperm, eggs, and newly formed embryos. Normally, these 2 receptors are activated by the naturally occurring signaling molecule anandamide. Anandamide formation by the enzyme NAPE-PLD is carefully balanced with its degradation by the enzyme FAAH, resulting in a finely tuned local “anandamide tone” in embryos and the oviduct. This balance is required for normal embryonic development, transport along the oviduct, implantation in the uterus, and full-term pregnancy.

The results of the study show that drugs such as THC persist and swamp these finely tuned signaling systems and as such the use of THC-containing drugs such as marijuana may lead to ectopic pregnancy and/or impaired fertility in women.

Pothead

November 28th, 2008 · No Comments

A pothead is one who habitually smokes marijuana which is often called “pot,” “grass,” “weed,” “reefer,” or “mary jane”.

Marijuana is a greenish-gray mixture of the dried, shredded leaves, stems, seeds, and flowers of Cannabis sativa, the hemp plant.

Most users smoke marijuana in hand-rolled cigarettes called joints, among other names; some use pipes or water pipes called bongs. Marijuana cigars called blunts have also become popular.

Unscientific Research About Marijuana Abuse

Here are comments from a previous distributor of marijuana regarding his observation of his pothead clients over the long term.

Potheads:

* suffer from poor memory
* are lethargic
* have low vitality
* have lower sexual appetite
* have abnormally coated tongues and bad breath
* are more susceptible to infection and colds that last for months
* can not smell or taste as well as nonheads
* have blood-shot eyes
* have pale skin

The above is an unscientific study but revealing anyway.

Scientific Research About Marijuana Abuse

Potheads – Regular Users of Marijuana:

* Heart begins beating more rapidly (within minutes)
* Blood vessels in the eyes expand making the eyes look red
* Experiences intense sensations, colors, and sounds
* Time appears to pass very slowly
* The mouth feels dry
* Hands may tremble and grow cold
* May feel depressed or experience anxiety, fear, distrust, or panic
* Short term and long term memory impaired
* Attention and judgment impaired
* Coordination and balance is impaired
* Lack self confidence
* Lack motivation and pursuit of goals
* Immune system’s ability to fight off infectious diseases is impaired
* Increases risk of chronic cough, bronchitis, and emphysema
* Increases risk of cancer of the head, neck, and lungs
* Students get lower grades and are less likely to graduate from high school
* Workers have more problems on the job such as increased absences, tardiness, accidents and job turnover

Marijuana Brain

October 29th, 2008 · No Comments

Chronic, heavy marijuana use during adolescence, which is a critical period of ongoing brain development, is associated with poorer performance on thinking tasks, including slower psychomotor speed and poorer complex attention, verbal memory and planning ability.

Research supported by the National Institute on Drug Abuse (NIDA) shows that it is evident even after a month of stopping marijuana use. There may be partial recovery of verbal memory functioning within the first three weeks of abstinence from marijuana, but complex attention skills continue to be affected.

Not only are their thinking abilities worse, their brain activation to cognitive tasks is abnormal. The tasks are fairly easy, such as remembering the location of objects, and they may be able to complete the tasks, but the adolescent marijuana users are using more of their parietal and frontal cortices to complete the tasks. Their brain is working harder than it should.

Girls may be at an even greater risk than boys.

Drug Addiction in Mexico Increases Dramatically

July 30th, 2008 · No Comments

According to a recent report in USA Today and information from the Mexican Health Ministry, new patients at drug treatment centers quadrupled since 2000.

The new border fence and intensified patrols by both Mexican and U.S. federal agents have made it harder for Mexican cartels to get street drugs into the USA.

Mexican President Felipe Calderón warned last month that cartels are no longer just trying to get drugs to the USA, but generate consumers “here in Mexico who will buy them, and buy them for the rest of their lives.”

“We used to be mainly a country of transit for drugs. Now we’ve become a consumer,” says Ricardo Sánchez, director of research for the health ministry’s rehab centers.

Prices of drugs have increased in the USA but have decreased in Mexico making it more available.

Marijuana Potency is Higher Than Ever

July 12th, 2008 · No Comments

The Office of National Drug Control Policy (ONDCP) and the National Institute on Drug Abuse (NIDA) recently released a report that revealed the levels of THC – the psychoactive ingredient in marijuana – has reached the highest-ever amounts since scientific analysis of the drug began in the late 1970s.

According to the latest data on marijuana samples analyzed to date, the average amount of THC in seized samples has reached a new high of 9.6 percent. This compares to an average of just under 4 percent reported in 1983 and represents more than a doubling in the potency of the drug since that time.

The image shown is referred to as a “steam roller” (peace pipe). The pipe is used by marijuana smokers. The smokers fill the bowl with cannabis, then put the hand over the end of the pipe nearest the bowl and the other end in the mouth. After lighting and inhaling until the chamber is filled with smoke, you then remove the hand and quickly inhale the collected smoke to have a stronger high.

“The increases in marijuana potency are of concern since they increase the likelihood of acute toxicity, including mental impairment,” said Dr. Nora Volkow, Director of the National Institute on Drug Abuse. “Particularly worrisome is the possibility that the more potent THC might be more effective at triggering the changes in the brain that can lead to addiction.

The increased potency of marijuana available in the United States also corresponds with other troubling research showing links between marijuana use and depression. See this article on marijuana and depression.

“Pot” smokers are self medicating to feel better but it is a false feeling as long term brain damage is being done, especially with heavy users.
