The brain gets used to you taking the drug. Some drugs will affect your neurotransmitters, or messages that get sent to your brain that regulates how we think or feel. You will eventually become dependent on the drug so if you stop you might feel sick or go through "withdrawal". Which people dont want to go through so they will continue to take the drug.
Highest risk body fluid would be blood because it has high nutritional value and pathogen is multiplying on there. Most pathogen will be transmitted by blood.
Droplet from cough also highly contagious since it easily contacts with any part of the body. Inhalation also makes the infection easier since it contacts mucosa.
Vaginal secretion and seminal fluid can transmit many virus but it depends on how many virus in the blood.
Saliva is composed by water and enzyme so it's low risk on virus spread. But it's on the mouth(which wasn't sterile) so it can be contaminated by various things.
In normal condition urine and spinal fluid is sterile, but in a case of infection, it can be contaminated.
Sweat is mostly water and salt so it's safe.
Dear Chairman,
I have some ideas on helping students achieve higher results. First idea I propose is making a study time where students can study in their most comfortable way possible. This promotes more learning and will make the process much faster as students will be doing it in a way that suits them. Another idea is to give lessons on how to be more productive at home and balancing everything to make time for self care and studying.
Sincerely, (your name)

Genetic testing can be used to tell if a person carries mutation of the CF (cystic fibrosis) gene. The test looks at a person's DNA, which is taken from cells in a blood sample or from cells that are gently scraped from inside the mouth.
Extra fact: More than 10 million Americans are carriers of one mutation of the CF gene.
Hope I helped!
