The drugs lecture was certainly an interesting one, and I found it to be very informative. Usually when the term drugs are mentioned it simply refers to hard/illegal substances such as meth, heroin, and cocaine. However, it is important to note that drugs should not be only associated with negative actions or addiction. After all the most used drug in the world is probably caffeine if I had to wager a guess, with how abundant and mainstream a morning coffee is considered. The slides which cover addiction really highlight the importance in being able to understand why an addict will continue to be an addict. I think the slide 27 titled ‘Theories of Drug Addiction’ where positive and negative reinforcement are discussed is paramount to understanding partially what an addict is going through. For example, it could be that the overuse of a certain drug can reduce the user’s discomforts. One more thing I want to point out from this lecture is that there is also a such thing as a ‘positive addiction’. Everything in moderation is key, even activities that are beneficial to our health such as working out. The effect of addiction to working out can lead to symptoms of exercise tolerance.
