Marijuana and Memory

This is an image of a rat brain with the different parts of the brain labeled.It's shown in recent studies that there are harmful long-term effects on the memory with the recreational use of marijuana. Studies using rats have shown that rats using marijuana before birth, after birth, or during adolescence have had problems later in life with memory tasks and specific learning. The hippocampus of rats on marijuana has also been effected. The reward system in rats has been altered because of the exposure to THC, the exposure has caused the animal to want self administer different drugs like heroin when giving the opportunity. Studies in humans have concluded that consistent marijuana users have shown impaired neural activity in the brain effecting memory, learning, and impulse control. A study in New Zealand found that marijuana is most harmful in adolescence and causes people's IQ to decrease and cannot be recovered because of the important growth, maturing, and connections made in the brain during youth. In the image below the orange and yellow areas are the areas where cannabiniod receptors are in the brain.

21st Century Drug Policy Goals


So far 23 states have aloud medical marijuana. In the government's 21st century drug policy the government is trying to reduce the number of young people taking drugs. The president wants to issue a Drug Free Community support group to try to keep the community clean of drugs. Also the government is trying to prevent drug addition by early detection and treatment by doctors and nurses. The government plans to use screening, brief interventions, and referral treatment to prevent the addiction. Then through the Affordable Care Act the government wants to offer treatment to negative effects of addiction. Plus the Obama Administration wants to have substance reforms to prevent the amount of incarcerations and prevent recidivism while protecting the public's safety. This the government hopes will help people recovering from drug addition to return back to society. The last thing the government wants to do is give people in recovery from drugs a voice to prevent drug addiction. The goal is to prevent  the recreation of drug use with out being forceful with the law.

Marijuana in the Lungs

Smoking marijuana has very harmful effects on the lungs. Marijuana causes chronic bronchitis in the lungs and damages the cells in large airways leading to persistent coughing, phlegm production, wheezing, and acute bronchitis. Marijuana suppresses the immune system making it easier to get  respiratory system infections. Marijuana users who are HIV/AIDS positive have a significantly increased risk of getting infections. Aspergillus which can grow in the marijuana is a fungus that can cause infections in the lungs if smoked.

How Marijuana effects teens

Marijuana is extremely harmful to the teenage brain. When marijuana is used by teens it effects their brain development they fewer neural fibers in the brain, decreased brain activity, and a smaller than average hippocampus. The hippocampus control learning and memory functions in the brain which in turn will make students doing marijuana perform poorly. In a Northwestern study of the effects of marijuana on the brain found that the brain of teens using marijuana appeared to shrink showing a decrease in neural fibers in the brain. Brains of teens using marijuana in the long term had a brain similar to someone with schizophrenia. Long time abusers of the drug have said that the drug has made it difficult for them to think, organize thoughts, and multi-task.

Primary Benefits of Using Medical Marijuana


Medical Marijuana for the Elderly


Doctors have found that cannabis is being increased in use by the elderly. Marijuana on the elderly has helped reduced appetite, low energy, insomnia, mental confusion, pain associated with stiffness of limbs, and glaucoma. The important thing to remember with medical marijuana is that people who do not abuse the drug and actually need the drug can get the positive effects. A study was conducted using forms of marijuana in oils, vapors, powder, and smoke three times a day for a year. This study was conducted by professor Raphael Mechoulam and Yechiel Gaoni who worked with the active ingrediant in marijuana THC and used the drug on 19 seniors from Hadarim Nursing Home. The results of the study were that the cannabis helped the seniors retain their weight, reduce muscle spasms, tremors, and pain and stiffness in their joints. Also most of the patients slept better too.
