Xylene can easily be purchased from paint and hardward stores. It can not be made at home.
Xylene affects the brain. High levels from exposure for short periods (14 days or less) or long
periods (more than 1 year) can cause headaches, lack of muscle coordination, dizziness,
confusion, and changes in one's sense of balance. Exposure of people to high levels of xylene
for short periods can also cause irritation of the skin, eyes, nose, and throat; difficulty in breathing; problems with the lungs; delayed reaction time; memory difficulties; stomach discomfort; and possibly changes in the liver and kidneys. It can cause unconsciousness and even death at very high levels (often seen similar to huffing).
