1. causes depression because it slows the central nervous system2. relaxes muscles and relieves tension

• it affects the heart function:

1. the drug enter the blood stream, the heart pumps blood containing the drug to the brain where it will affect how people feel

Disadvantages :• it affects the liver function:

1. the liver breaks down because of the chemical structure of drugs

• it affects the lungs function:

1. the lungs provide the oxygen directly to the body

2. anything that is inhaled enters the blood and ultimately the brain very quickly

3. The lungs' ability to absorb large amounts of these drugs in a short space off time, roughly 8 seconds, mean that the effects can be almost instant and very powerful.
