What is chemistry? Chemistry is the branch of science concerned with the identification of the substances of which matter is composed; the study of their properties and how they interact, combine and change, and the use of these processes to form new substances. Chemistry finds its way into the medical field in several different ways. Why is chemistry linked to medicine? Chemistry is related to medicine because to understand medicine you need to understand how it works and how different chemicals react when combined. The composition, structure and properties of the material are all important factors in correctly creating a medicine. Chemical composition refers to the individual chemicals that make up a substance. Chemical structure theory states that chemical compounds are not a random group of atoms and functional groups, but structures formed in a definite order. Chemical properties are properties used to characterize materials in reactions that change their identity. “Medicinal chemistry is the application of chemical research techniques to the synthesis of pharmaceutical products. In the early development of medicinal chemistry, scientists were primarily concerned with the isolation of medicinal agents found in plants. Today, scientists in this field are also concerned with the creation of new synthetic drug compounds. Medicinal chemistry is almost always oriented toward drug discovery and development (acs.org). How does composition work? (Chemical composition of marijuana) In medical marijuana there are 400 natural compounds, of which only eighty come from the cannabis plant, they are known as cannabinoids. There are 5 major cannabinoids in medical marijuana. THC is one of the cannabinoids...... middle of paper......, and even road safety. The effect it has on memory only occurs over a long period of time in excessive and abusive users of this drug. High school dropouts are typically heavy drug users, with marijuana being the gateway drug. Which leads to heavier drugs like crack/ect. Lack of educational tasks also occurs when using this drug, most common also among heavy/abusive users. Consuming marijuana on the road is very dangerous and risky because it has the same effects (vision/consciousness) as alcoholics, which is very illegal on the road. I think medical marijuana is going to have a high impact on life. I the future, as well as a negative effect on tomorrow's life. Because of all the cases of glaucoma and all the different traits and types of cancer. Medical marijuana mixed with other chemicals could one day cure cancer, based on what we know..
