Different types of drugs affect your body in different ways, and the effects associated with drugs can vary from person to person. How a drug effects an individual is dependent on a variety of factors including body size, general health, the amount and strength of the drug, and whether any other drugs are in the system at the same time. It is important to remember that illegal drugs are not controlled substances, and therefore the quality and strength may differ from one batch to another. Drugs can have short-term and long-term effects. These effects can be physical and psychological, and can include dependency. You may act differently, feel differently and think differently if you have taken drugs. And you may struggle to control your actions and thoughts. You might begin to use drugs without thinking about any harm to your body. You might think drugs won't become a problem because you are only a casual user. The more you take a drug, the more likely you are to build up a tolerance to its effects. This can lead to the need to take larger doses to obtain the effects of the drug. For this reason, evidence suggests that after prolonged use, many drugs can cause dependence. Drug dependence can quickly begin to affect your psychological and physical health, and can also affect your work and social life. It is important to remember that there is no safe level of drug use. Be careful when taking any kind of drug.
C. Do Not Resuscitate.
Performing CPR to revive a patient with DNR record is both an ethical and legal dilemma. Ethically, it is necessarily expected from health care workers to perform and provide life prolonging or saving responses. However, the patient has the right to choose whether he or she should receive treatment and which must be respected. DNR order can be documented through the personal expression of the patient of refusal of treatment in front of witnesses. When the patient is incapacitated or does not have the right mind to make the decision, another way a DNR order can be obtained and documented is through the a legal guardian, legal spouse, adult child, parent, adult sibling or nearest adult relative.
D. Cancer is the answer to your question as those types of therapy cannot treat the previous diseases/disorders
The pineal gland is in charge of producing melatonin which regulates your body's rhythms (including your circadian rhythm, a rhythm that tells your body if it is night or daytime). This would cause your body to think it is earlier than it actually is, keeping you awake.
