Drugs alter the chemistry of the brain

In our last class we talked about how drugs alter the chemistry of the brain, specifically by blocking the protein channels that would otherwise reabsorb dopamine.

The picture above shows how methamphetamine disrupts this process.  We have also talked about how different routes of administration result in different levels of chemicals in the body. 

Today we discussed the differences between drugs and medicines as well as Drug Abuse Is Voluntary; Addiction Is Compulsive.
