The synapses in the brain are often the main target of a drug, altering the perception of something at the point of perception. When a drug is taken, it attaches itself to receptors in the brain, which have a pattern chemically similar to the neurotransmitters that send and receive messages in the brain. Perrine makes the analogy of a drug to receptors as a hand to a doorknob. Because certain drugs can attach themselves to these receptors, they may become blocked, and the neurotransmitters originally being sent by the brain's neurons are forced to wander around the brain until it can find another similar receptor, possibly creating a false signal (Perrine, 1996). The physiological responses created by these false signals, sent by both the drug and the extraneous neurotransmitters are what are perceived to be the effects of the drugs. However, the effects of drugs vary greatly from person to person. Perrine states that are four main aspects to keep in mind when cons...
