The Science of Addiction

Multiple drugs are used and abused such as Cocaine and Methamphetamine. Though these drugs may seem different they may be very similar. They have similar effects on you and your brain. Cocaine and meth both cause the dopamine to over stimulate the cell. Meth does this by causing the dopamine transporters to work in reverse, releasing the dopamine into the synaptic gap. Cocaine blocks the dopamine transporters, trapping the dopamine in the synaptic gap. Now, since the dopamine can't get into the cell it continuously binds to the dopamine receptors overstimulating the cells.

These are different ways people release the chemical into the body. The 4 ways are smoking, intranasal, injection, and ingestion. The fastest way to get a drug to your brain is smoking followed by injection. Then intranasal and the slowest is ingestion.

People become drug-addicts when the presences of drugs in the body become usual.
