Marijuana and the Biological Bases of Behavior
Marijuana is the dried leaves and flowers of the hemp plant
Cannabis sativa. Like all plants, it's sensitive to the environment
where it grows. Some of the names for it are Mary Jane, pot, weed,
grass, herb, ganja or skunk. The brain has many responses to marijuana.
Marijuana can cause people to lose focus on events around them. For
some it makes them more aware of their physical sensations. For others,
there are numerous other effects. All forms of marijuana are mind-
altering.
All of the changes are caused by chemicals that affect the brain.
More than 400 chemicals are in the average marijuana plant. When
smoked, heat produces even more chemicals. Different weather and soil
conditions can change the amounts of the chemicals inside the plant.
Marijuana grown in one place might be chemically stronger than grown in
another. Marijuana's effects on the user depend on it's strength or
potency, which is related to the amount of THC it contains.
Marijuana causes some parts of the brain, such as those governing
emotions, memory, and judgment, to lose balance and control. Marijuana
can speed the heart rate up to 160 beats per minute. Dilated blood
vessels make the whites of the eyes turn red. Panic feelings may be
accompanied by sweating, dry mouth, or trouble breathing. Much like
tobacco smokers, marijuana smokers may experience a daily cough and
more frequent chest colds. Animal studies have found that THC can
damage the cells and tissues in the body that help protect against
disease. When the immune cells are weakened you are more likely to get
sick.
When someone uses marijuana, these chemicals travel through the
bloodstream and quic...

Dr. Maya Angelou was born on April 4, 1928 in St. Louis Missouri. Angelou was raised in St. Louis and Stamps, Arkansas. In Stamps she was faced with the brutality of racial discrimination, and a very traumatic incident where she, she was raped by her mother's boyfriend when she was eight, but because of this she also developed an unshakable faith and values of traditional African-American family. (Angelou)This shaped her poetry and her involvement in the arts. Where she began to sing and dance and planned to audition in professional theater but that didn’t work out well because she began working as a nightclub waitress, tangled with drugs and prostitution and danced in a strip club. In 1959, she moved to New York, became friends with prominent Harlem writers, and got involved with the civil rights movement. In 1961, she moved to Egypt with a boyfriend and edited for the Arab Observer. When she returned to the U.S., she began publishing her multivolume autobiography, starting with I Know Why the Caged Bird Sings as well as several books of poetry and the third being Still I Rise in published in 1978. (Maya Angelou is born) Because of this life of hardship shaped her to who she is and was the inspiration for a lot of her poetry.
The book The Adventures of Huckleberry Finn tell the tale of a young boy who embarks on an adventure, one that leads him to find himself. Throughout the novel Huck develops a sense of morality that was always there to begin with, but not nearly as developed as it is by the end of the novel. Through living on his own, independent of societal and peer pressures, Huck is able to identify his own morals in defining what is 'right ' or 'wrong '.
Huck has been raised in a high-class society where rules and morals are taught and enforced. He lives a very strict and proper life where honesty and adequacy is imposed. Huck being young minded and immature, often goes against these standards set for him, but are still very much a part of his decision-making ability and conscience. When faced to make a decision, Hucks head constantly runs through the morals he was taught. One of the major decisions Huck is faced with is keeping his word to Jim and accepting that Jim is a runaway. The society part of Hucks head automatically looks down upon it. Because Huck is shocked and surprised that Jim is a runaway and he is in his presence, reveals Hucks prejudice attitude that society has imposed on him. Huck is worried about what people will think of him and how society would react if they heard that Huck helped save a runaway slave. The unspoken rules th...
During Huck’s Second Crisis of Conscience episode in Mark Twain’s Adventures of Huckleberry Finn, Huck’s sheer tenacity to uphold his friendship with Jim indicates that a human being’s sense of camaraderie displaces racism. Through his resolution to no longer base his actions on what is most convenient for him, Huck demonstrates promising development concerning his conscience and his heart. Furthermore, Huck matures by exhibiting amiable emotions towards Jim and deciding to protect Jim’s freedom at all costs. Notwithstanding, Huck’s maturation has space for refinement because, pertaining to his overall grasp of slavery, Huck needs to understand the cruelty that enslavement harnesses.
Mark Twain’s masterpiece The Adventures of Huckleberry Finn through much criticism and denunciation has become a well-respected novel. Through the eyes of a thirteen-year-old boy, Huckleberry Finn, Twain illustrates the controversy of racism and slavery during the aftermath of the Civil War. Since Huck is an adolescent, he is vulnerable and greatly influenced by the adults he meets during his coming of age. His expedition down the Mississippi steers him into the lives of a diverse group of inhabitants who have conflicting morals. Though he lacks valid morals, Huck demonstrates the potential of humanity as a pensive, sensitive individual rather than conforming to a repressive society. In these modes, the novel places Jim and Huck on pedestals where their views on morality, learning, and society are compared.
While Huck’s constant lies while narrating the novel makes the authenticity of certain events doubtful, it serves a much greater purpose of allowing the reader to indirectly see the continued improvements and declines of Huck’s moral judgment. At some points, he serves only himself; at other key events in the story, he creates elaborate lies that help others. The moral development of Huck makes itself apparent in the changing lies of Huck, allowing readers to observe the events taking place within Huck’s mind with ease.
Similar to other works by Shakespeare, such as The Taming of the Shrew, A Midsummer Night’s Dream embellishes the pressures that arise between genders dealing with complicated family and romantic situations. The plot includes a duke who is going to marry a woman he conquered in battle, the king and queen of the fairies embroiled in a fight so fierce that it unbalances the natural world, and a daughter fighting with her father for her right to marry the man she chooses. The girl’s father selects Demetrius to marry his daughter, but she is in love with another man, Lysander, who loves her in return, and her friend Helena is in love Demetrius, but he wants nothing to do with her. Considering the fact that males were dominant during that era, whereas, men chased women, and women remained submissive, Shakespeare dallies with those traditional roles and there are several possible reasons why. Perhaps he made women a stronger force in his plays because he wanted to give his audience a break fr...
The debate concerning recreational and medical use of cannabis has historically been incredibly controversial and its popularity is increasing. Many claim that there are no downsides to its use, often falling back on the “alcohol is worse for you” argument, while those who oppose its use say otherwise. In 2013, the Substance Abuse and Mental Health Services Administration (SAMHSA) surveyed 70,000 Americans 12 years and older and found that 7.3% of Americans regularly used marijuana in 2012, showing a rise in use over the last several years. While cannabis is still considered an illegal substance in the majority of the country, several states are beginning to shift their views, allowing for the use of medical marijuana in some and even full legal recreational use in others, such as Colorado. The main question driving this debate is how does cannabis affect the mind? Legalization very much depends on peoples’ health and safety concerns, and so in this paper I discuss cannabis and its effects on cognitive function both short- and long-term.
Morality has always been defined as having either a good or evil conscious. There is always a choice that a character makes that defines their moral integrity in a literary work and distinguishes them as the hero. In Mark Twain’s story, “Adventures of Huckleberry Finn”, not only does Huck encounters a number of moral circumstances where he or other characters displays situations in which moral ethics is called to questioned, but it proves that despite the religious influence and social expectation, it is through Huck that in order to do what is morally right, one must challenge the moral teaching of the world. Through observation of his world, Huck makes morally ambiguous choices that though may be against his moral teachings. Choice proves that to act on one’s own judgement despite societies expectations demonstrates that hypocrisy of the community as Twain clearly depicts and satirizes Southern society, he depicts the violence and racism that was described as “silvilization”(Kelly). As the community in Twain’s novel follows the general religious teachings and distinguishes the binaries associated with good and evil, Huck is forced to forsake these teachings and goes on a journey to discover his own moral understanding.

When getting high becomes more frequent, the effects become more serious. The brain, or control center, is greatly affected by marijuana. The average person may not know the brain does not fully develop until their mid-twenties. Hence, why most states set the legal drinking age to twenty-one years old. States also contemplate on the legalization of marijuana because drug use can harm the brain at any age, but teenagers and children are more susceptible to long term damage due to incomplete brain development. One way that marijuana affects the brain includes THC stimulating the brain cells which create the high state of mind. The stimulation can cause hallucinations, paranoia, uncoordination, and impairment. The ability to remember and judgement
In the book, The Adventures of Huckleberry Finn, the protagonist is faced with many moral dilemmas. Huckleberry Finn is barely an adolescent who is used to skipping school and horsing around with his friends. Regardless, he is forced to make decisions that no person should have to make, even though he is only a child. Huckleberry is an outstanding role model and a model of what a human being should represent. Even though Huck is surrounded by corruption and is led by examples that do not recognize right from wrong, he is still able to address nonconformity. He makes the most morally upstanding decisions while under stress and the disapproval of society. The Adventures of Huckleberry Finn is about a young boy who grows up without the leadership of a father to guide him as he struggles with decisions that heavily impact those around him. Huckleberry makes the conscious decision to help a runaway slave escape to his freedom. He struggles with this decision for an extremely l...
Marijuana and alcohol use have been thought to be detrimental to brain function. The purpose of this experiment was to observe, and test, what kind of effects marijuana and alcohol have on the brain. This experiment is a longitudinal study that consisted of the participants using alcohol and marijuana over a period of three years and being evaluated by a series of tests. These tests measured multiple aspects of cognition such as memory and how quickly they could understand and sort material. The partakers were chosen from students in California whose ages ranged from 16-19 years old, therefore these students are in late adolescence and early emerging adulthood. It is important to note these stages because the use of drugs can alter the brain
Jessie is portrayed as a light-skinned and somewhat physically unstable woman in her later thirties or early forties (Norman 1528). Jessie Cates struggles with family problems and has just now seen improvement in her epilepsy in the last year. Beginning to regain some parts of her memory she makes a decision that will change her life forever. ’night, Mother” is a play about a seemingly futile life…a life fraught with turmoil, tragedy and a failed existence. In this sense, death breaths life because it symbolizes the freeing of oneself from the bonds of this miserable and almost pointless subsistence. It probes the concept of death to understand the term “quality of life.” This is what ‘night, Mother is about.
The love of Hermia and Lysander is put to the test when many events cause disruptions in the course of their true love. Hermia’s father, Egeus, is a very powerful figure in the life of Hermia and greatly impacts the love of Hermia and Lysander. However, he greatly disapproves of Lysander and instead wishes his daughter marry Demetrius so much that if Hermia does not marry Demetrius she will, “either to die the death, or to abjure for ever the society of men” (24). This quotation, said by Theseus, the Duke of Athens acting as Egeus’s messenger, means that if Hermia does not marry Demetrius, “a worthy gentleman”(24) in Egeus’s eyes, she will face death or fore...
