Cannabis, or marijuana (Cannabis sativa) is known for its psychoactive properties and its illegal recreational use to get “high” or “stoned”. The main psychoactive chemical in cannabis is tetrahydrocannabinol, commonly known as THC. This was isolated in 1964. Another important component, nonpsychoactive cannabidiol (CBD), was identified in 1963. All together, there are more than 60 pharmacologically active compounds called “cannabinoids”.
In the 1980s the endoCannabinoid system was discovered. It is a complex neurotransmitter or signalling system consisting of receptors, endogenous ligands and enzymes that exists throughout the central nervous system (including the brain) as well as the peripheral nervous system.
This endocannabinoid system has been found to express elevated signalling in various neurodegererative diseases including Parkinson’s disease, Alzheimer’s disease, allergic encephalomyelitis and multiple sclerosis. The purpose of this activation seems to be to reduce neuronal hyperactiviety and local inflammation which could cause damage as well as to reduce tremors and spasticity. Continue reading →
Is Vaping Safe? E-cigarettes are battery powered devices that heat a liquid to form a vapor that you inhale. While that vapor does not contain the tars found in burning tobacco cigarettes, the vapor does contain other chemicals that could cause harm.
The liquid typically contains combinations of propyleve, glycol and glycerin. Liquids may also come with varying levels of nicotine and flavors that are carried along with the vapor for inhalation.
And, while electronic cigarettes do not provide your lungs will all the tars or alkaloids of conventional tobacco cigarettes, they are not a safe way to obtain nicotine.
The market for e-cigs is booming. It is estimated that by 2023 the market will be worth $48 billion. Because these devices are not traditional cigarettes, the tobacco companies have gotten back into advertising their brands of these nicotine delivery systems in a big way. Some of these big tobacco electronic cigarette brands include VUSE, Vype, Mark Ten, and Blu.
E-Cigarettes : Welcome Back, Big Tobacco – the fifth estate
Big Tobacco is trying clean up its image, moving into the booming e-cigarette business which continuing to peddle the deadly tobacco products. This has left public health officials in Canada, the U.K. and the US concerned.
Stress can cause poor health and make you look exhausted and haggard. Stress is a risk factor for cardiovascular disease, poor immune function, premature aging, high blood pressure, obesity and even diabetes. Exactly how stress brings about the early onset of age-related disease is not entirely clear. Many believe that stress increases the rate of aging within the cells themselves.
Cellular aging is associated with oxidative stress, lowered telomerase activity, and shorter telomere lengths. These factors affect the longevity of your body’s cells.
Telomeres are the caps or ends of chromosomes which provide protection and help give stability to the chromosomes. Telomeres are composed of terminal sequences of TTAGGG DNA base units at the ends of all chromosomes that signify the end of chromosomal information. At conception there are approximately 2,500 TTAGGG sequences as “end caps” to chromosomal data.
Telomers are a target of oxidative damage and become damaged and shortened due to the action of free radicals.
Psychological stress itself seems to accelerate the shortening of telomeres. In one study 58 mothers were studied. 19 of the mothers had a healthy child while 39 mothers cared for a chronically ill child. The research found that (adjusted for the age of the mother) the more years of caregiving, the shorter the mother’s telemores, the lower the telomerase activity and the more oxidative stress the mothers experienced.

Almost no one in America is getting all the nutrients they need for a healthy life. Neither elite athletes nor sedentary people are supplying enough nutrients to their bodies to restore or maintain their health.
Deficiencies of micronutrients like vitamins and minerals can can cause DNA damage just like excessive doses of radiation. These deficiencies cause single and double-strand breaks and oxidative lesions that are similar to the DNA damage of radiation. This damage can lead to numerous diseases.
Around 80% of young people and more than two-thirds of adults are not getting the recommended nutrients from real fruits and vegetables. The 25% of people eating the fewest fruits and vegetables have nearly twice the cancer rate as the 25% of the population consuming the most fruits and vegetables.
