Drug testing should be done in every sector of the society, not only in schools but also at work. This should be a mandatory process before a person can be admitted in a school or be hired in work. If drug testing is required before anyone can get a driver's license, why not require it also to aspiring students of a university before they can be admitted. There is no difference in that.
A school is designed to allow students to learn, it should be a place with a good learning environment, it is a place where we can implore knowledge. How can one person be encourage to learn if his or her seatmate is a drug addict. How can you call a school a good learning environment if your environment is surrounded with drug addicts. In some or most instances, these persons who are addicted to drugs can be the root of violence inside or outside the campus. They can also influence other people to try drugs themselves and eventually become drug addicts just like them. So, it should be a requirement for a school to drug test not only the students but also the employees and the teachers to make it a good environment for learning and a place for knowledge.
This may be a case for an argument, some may question where is the right for education. I say: how can a person be educated if he is into drugs? Who in the right mind wants to go in a school full of drug addicts? May be the drug addicts themselves...If a person wants education he should be a person who who is on his right mind and if one wants to be admitted into a school, he should be drug free.A school should be a safe place to study that's why I agree on drug testing before admission...

Endocrine Glands secrete and produce body molecules called Hormones. These body molecules called hormones are released to our blood stream and are then distributed to the other parts of the body where they bring out physiologic responses from specific cells.
There are 2 mechanisms of Hormonal Action: the 1st mechanism involves non-steroid hormones like peptides, amino acids and sphingolipids, and the 2nd mechanism involves generally steroid hormones like testosterone and estrogen.
Steroid hormones contain structures that are lipid-soluble and synthesized or derived from cholesterol. with the basic nucleus which is CPPP (cyclopentanoperhydrophenanthrene). Steroid hormones pass through the target cell’s cell membrane which can cause changes within the cell. Unlike non-steroid hormones, steroid hormones can do this because they are fat-soluble. Cells membrane contains phospholipid bilayer which forbids fat-insoluble molecules from diffusing into the cell.
Steroid Hormone Mechanism of Action
The steroid hormone mechanism of action can be summarized as follows:
- It first passes through the cell membrane of the target cell.
- It binds with the cytoplasm in a specific receptor site.
- The receptor bound steroid hormone goes inside the nucleus and binds on the chromatin with another specific site.
- Then the production of proteins takes place when the steroid hormone-receptor complex calls for the production of messenger RNA (mRNA) molecules.
