After reviewing the lecture on drugs, I found it to be very informational and interesting. Psychoactive drugs can fall under many categories of different things, but they all have similar characteristics of a chemical substance that alters mood and behavior. There are legal substances like caffeine, alcohol, and nicotine that may not seem like a psychoactive drug but truly are. Other substances such as amphetamines, cannabis, cocaine, and opiates that are illegal and even gambling are the more obvious ones that come to mind when you hear the word psychoactive drugs.
The lecture continued to detail addiction and the characteristics. This description of an intense craving, seeking out, and use of a particular drug is what makes up addiction. Cravings that come with addiction give a person a feeling of an unstoppable urge for the drug to seek a highly desired pleasure. Neurons and neurotransmitters send impulses throughout the body to communicate the need for the drug. The end result of this is the dopamine spike we get with the pleasures that we indulge in. The withdrawal and behavioral patterns we fall victim to is what can make up a problem and lead anyone into addiction.
