Heroin is so much more potent than morphine because it has a different function, structure, and polarity. The function of heroin and morphine tells us what the drug does when it hits the brain. Morphine, when it hits the brain it interacts with the mu opioid receptors. Morphine after entering the brain fits into these mu opioid receptors and releases a chemical signal to releases less Gaba. Gaba inhibits dopamine so less dopamine is made.
"John Doe" English H101 Prof Crowley 9 December, 2010 Final Draft Alternatives to Hallucinogens and the Occurrence of DMT; Should it be illegal? A Hallucinogen is a psychoactive drug that causes changes in perception, emotion, thought, and consciousness. With that being said, these are extremely powerful drugs. This state of consciousness is very different from any state of consciousness we know. It's been described as a Trance, Meditation, and Dreams.
Recently newer forms of long lasting codeine tablets have been developed, some of whom may last up to twelve hours. Codeine addicts have been known to mix the drug with alcohol to enhance their high. This mixture is simply referred to as a cocktail, but this kind of cocktail is lethal. Mixing codeine with alcohol greatly increases the probability of overdose, and such overdoses have led to countless deaths. Most of the high profile deaths associated with codeine have affected those associated with the hip hop industry.
From neuroscience perspective, cocaine, Xanax, and marijuana that are identified in Houston’s body attribute to imbalance of neurotransmitters, causing depression, which results in Whitney Houston’s committed suicide. To begin with, cocaine is a stimulant that can produce a rush of euphoria and lead to lack of dopamine, serotonin, and norepinephrine. To understand how the imbalance comes, we should consider how neurotransmitters work in the brain. There is a junction called synapse between the axon and the dendrite, and neurotransmitters enable neural information to across the synapse to achieve neural communication. After the neurotransmitters stimulate the receptors on the receiving neuron, excess chemicals are taking back up into the sending neuron to be used again (lecture).
once a psychedelic is taken it completely disrupts normal communication According research and Google this drug seems to have a long lasting effect on people who are abusers in many ways. According to Live Science, “ many people report intensely spiritual experience while taking the drug and some studies suggest that one transcendent trip can alter a person's personalities on a long term basis.” Most individuals who have taken this drug are more likely open to a lot of new experience and are more aware and or appreciative of arts and emotion etc. Studies have shown that Psilocybin the main
Amphetamines are used to treat a variety of medical issues but like cocaine, illicit drug use in the 60s caused the federal government to become concerned about dependency and illegal activities. Prolonged uses of the drug can cause psychotic behavior, depressed moods and dependency can develop. Cocaine and amphetamines both interact with neurotransmitters and higher doses of each both alters
The good thing is that some of the effects of chronic methamphetamine abusers appear to be, at least partially, reversible. Moreover, the increased risk of stroke from the abuse of methamphetamine can lead to irreversible damage to the brain. Long term effects may include: addiction, psychosis, including paranoia, hallucinations, repetitive motor activity, changes in the brain structure and function, memory loss, aggressive or violent behavior, mood disturbances severe dental problems, weight
All of these actions are symptoms of meth mouth. A major consequence of meth use is overdose. When you overdose on methamphetamine the effects and consequences may cost the user their life. If the user overdoses on meth it can cause them to lose consciousness, have a seizure, and their heart may stop beating (Methamphetamine Abuse). Methamphetamine users may be more active with sexual activity, which can affect them later on.
One state law says that the definition of potential for abuse means that a substance has properties of a central nervous system stimulant or hallucinogen. This can create a hazardous euphoric feeling which can numb the users’ judgment. In a large number of cases, the user diverted from legal channels and distributed through illegal channels (Schmalleger, 2012). Anti-drug laws at the state level show a surprising degree of uniformity. Such uniformity is due to the fact that almost all states have adopted some version of the Uniform Controlled Substances Act, which was proposed in 1972 by the National Conference of Commissioners on Uniform State Laws.
Ecstasy (known as MDMA) is a derivative of amphetamine that acts on several neurotransmitters. It mainly increases serotonin by causing release and blocking reuptake. In the past, it was considered a safe sensation enhancer, but now it is found to impair cognitive abilities (language tasks), cause depression, and specifically poison neurons through a process known as neurotoxicity. Subjective Effects: MDMA is classified as a stimulant and psychedelic drug causing mild hallucinations, along with an intense euphoric, energizing feeling (Ecstasy, 2005). Users will report a powerful experience of increased happiness, sociableness, self-confidence, empathy and sensation to touch (Ecstasy, 2005).
