The usage of recreational drugs has a negative effect on the body, and can interfere with one’s memory. The main question is whether this addiction to recreational drugs is the main cause of the mind that interferes with the issue of truth and memory and how is it this shown by creative nonfiction writers. I argue that the addiction to such drugs as cocaine and crystal meth can mess with the author’s cognitive ability, therefore tying it to which ties into memory. When the authors are addicted to these drugs, their brains are affected to the point that they can no longer distinguish between truth and memory and thus result in blurred and false memories.
Many people use drugs once in a while. Be it for pleasure, stress, or as a profession, it cannot be denied that drugs are affecting many people’s daily lives. Drugs are not the problem in the issue of memory. When one indulges too deeply with drugs, the stimuli that is need with the drugs does not come as easily and gradually progresses into a habit or otherwise known as an addiction. What this paper will attempt to address is how serious addiction can make memory impairment and is this enough to affect the lives of these people.
Dopamine is a neurotransmitter with the function of controlling emotions and impulse among others. This is usually stimulated by “rewards” (Newton), which range from reading books to eating, for when there is excitement, this is released by neurons. Similarly, when one uses drugs, the signals that dopamine sends out are disrupted, causing a reduction in cognitive function. Research has proven that this dopamine is what brings out the addictive aspect of drugs. According to the National Institute on Drug Abuse, “drugs such as marijuana and heroin can a...

Can memories be biased? Researchers Postarino and Doyle-Portillio (2013); Bernstein and Loftus (2009); and Bartholomew (2009) found increasing evidence to suggest that the answer to this question is yes. Explicit and implicit memories are encoded differently, but it appears both can be fallible. Also worth noting, is that this can happen without a person conscious awareness. Kolb and Whishaw (2014) examined studies that gave participants a list of words, then gave them a second list. The second list contained some, but not all items from the first list, but many participants thought the word sugar was on both, when in fact it was only on the second. Similar words like cake, sweet, and candy were on the first so this seemed to confuse participants. This phenomena researchers refer to as false memory. False memory is different from a lie; unlike a lie, the individual in this case may give false account of the past truly believing that he or she is telling the truth. In other words, false memory can simply be defined as mental experience that is wrongfully considered as the truthful representation of the past. False memories can result in both minor and serious consequences Bernstein & Loftus, 2009; Bartholomew, 2009).
The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
Drugs seem to cause surges in dopamine neurotransmitters and other pleasure brain messengers. However, the brain quickly adapts and these circuits desensitize, which allows for withdrawal symptoms to occur (3). Drug addiction works on some of the same neurobiological mechanisms that aid in learning and memories (3). "This new view of dopamine as an aid to learning rather than a pleasure mediator may help explain why many addictive drugs, which unleash massive surges of the neurotransmitter in the brain, can drive continued use without producing pleasure-as when cocaine addicts continue to take hits long after the euphoric effects of the drug have worn off or when smokers smoke after cigarettes become distasteful." (4)
Dopamine is a reward chemical in the brain which rewards us every time we do something positive. Addiction comes from that chemical and can be created from various activities. Someone might enjoy jumping off a cliff, eating food, taking drugs or even play video games. Every time your brain enjoys something, dopamine is release and you start feeling good. The reason drug addiction is more complex, your brain will create more dopamine the more drugs you take. Eventually, your body will fight off the foreign product and dopamine will be created in too high dosage. Your body will become addicted to the dopamine, not the drug as previously thought by doctors.

A girl named Sarah who was interviewed by channel 6 “true life on ecstasy “ had done ecstasy for 3 years. However, the mistake in her part was that she had done it almost EVERY day. When she had gotten her brain scanned, she had a brain of a 75-year-old woman who had multiple strokes. Sarah at the time was only 25, but take into consideration that she more than “abused ” the drug.
Socrates’ Doctrine of Recollection is invalid because of the flawed procedure that was employed to prove it, its inability to apply to all types of knowledge, and the weakness of the premises that it is based on.
Nearly all drugs of abuse increase dopamine release. Dopamine is an important neurotransmitter in drug abuse and addiction. Dopamine plays a role in reward-motivated behaviors, motor control and important hormones. It’s known as the “feel good hormone” which is why people abuse drugs that increase the release of dopamine. Since life is unpredictable, our brains have evolved the ability to remodel themselves in response to our experiences.
The use of drugs is a controversial topic in society today. In general, addicts show a direct link between taking drugs and suffering from their effects. People abuse drugs for a wide variety of reasons. In most cases, the use of drugs will serve a type of purpose or will give some kind of reward. These reasons for use will differ with different kinds of drugs. Various reasons for using the substance can be pain relief, depression, anxiety and weariness, acceptance into a peer group, religion, and much more. Although reasons for using may vary for each individual, it is known by all that consequences of the abuse do exist. It is only further down the line when the effects of using can be seen.
