The medicinal properties of cannabis have been recognized for centuries, and it has been used informally in traditional Chinese and Indian medicines, and more recently in western cultures without medical approval, to treat a wide range of symptoms. Over the last decade, interest in the medicinal benefits of cannabis has started to garner attention, and consequently there has been an increase in research to provide evidence of these medical effects (1).  

Many western countries, including the United States, Canada and Germany now allow the medical use of cannabis. In Germany, cannabinoid medications prescribed by a physician to patients with severe diseases and no alternative treatment options are covered by health insurance (2).

The principal cannabinoid compounds derived from the cannabis plant are delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD) and 

The World Health Organization (WHO) defines air pollution as the "contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere." This International Clean Air Day, let's try to clean up our act and strive for clean air and blue skies by making a concerted effort to reduce our carbon footprint.

Common sources of air pollution include fires, motor vehicles, power plants, and other industrial activities. The pollutants that pose the greatest public health risk include particulate matter, carbon monoxide, lead, ozone, nitrogen dioxide, and sulfur dioxide. Exposure to these pollutants can cause respiratory conditions and diseases such as cancer, heart disease, and stroke. According to WHO, 99% of the world's population breathe heavily polluted air that exceeds their recommended

What is Chemical Oxygen Demand?

Chemical oxygen demand (COD) is the amount of dissolved oxygen needed to oxidize organic matter present in water. COD testing is conducted to determine how much organic matter is present in a water sample and how much oxidation will occur. COD testing can also be used to determine the levels of inorganic chemicals present in a sample, [1] and is used to quantify pollution levels in water.  A higher COD value indicates greater pollution levels in a water sample.

What is BOD and How Does it Differ from COD?

Biochemical or Biological Oxygen Demand (BOD), is the amount of dissolved oxygen required by aerobic microorganisms to break down organic matter present in water biologically. While COD and BOD can both be used to determine pollution levels in a water sample, COD is an indication of how much oxygen is required break down organic
