Your blood stream carries them.
The chemicals in your brain do not 'get there'. They are always with you from when your brain starts to form before you are born. Brain cells, however, die and are created millions of times in a week. Fascinating, isn't it?!

Chemicals affect the taste sensation communicated to your brain, from sweetness through to sourness.

The brain is not protected from chemicals that are ingested or absorbed through the skin.
It makes chemicals. For example, chemicals from and to the brain and stomach help you to know when you are hungry/full.
The blood brain barrier blocks chemicals from entering brain tissue.
No set answer. Depends on the individual. There are chemicals that appear in the brain naturally, and then there are chemicals (drugs, medicines, toxins, etc.) that are put into the bloodstream from outside sources.

When huffing volatile chemicals, the gases quickly get absorbed in the blood stream through the nasal cavity to are taken directly to the brain. The brain is then deprived of oxygen, which causes dizziness. The chemicals then can cause permanent damage to the brain cells. Huffing chemicals kills more brain damage than any illegal drug out there.

Chemicals are natural or artificial.
Your brain is like a main circuit board and medications are given to balance the two chemicals in the brain. The doctor will keep you on the medication for how ever long they feel it will take and when you are ready to come off it please work with your doctor and slowly wean yourself off them. I was on a SSRI and that's what I did and I was just fine. The medication helped balanced the chemicals in my brain and I did just fine after that. Cognitive Therapy and counseling along with this are a MUST and you learn good coping tools to deal with stress. Medications such as SSRIs or sedation's are simply a band-aid.
Brain tumors can develop from abnormal growth of cells in the brain. The exact cause is not always known, but factors such as genetic mutations, exposure to certain chemicals or radiation, and family history can contribute to their development. Brain tumors can also arise spontaneously without a clear cause.
It is overrun with chemicals and brain damage will result.
