Describe the major aspects of amphetamine psychosis and its relationship to paranoid schizophrenia Amphetamine-induced psychosis has a number of key aspects that make it different from other drug-related psychoses. The primary aspects include the stimulation of interpretive mental activities that involve paying more attention to details and repetitive searching and sorting behavior. The intermediary aspects are a development of sensitive keenness, which develops into a constant enjoyable curiosity and habitual inquisitive behavior. This behavior is then projected to others (persecution). The enhancement of this sensitive keenness leads to hallucinations that are usually auditory in the start but later become visual and physical. These aspects of amphetamine psychosis are closely related to those of paranoid schizophrenia. Indeed, according to a study published in the British Journal of Psychiatry, out of 14 cases of patients admitted with either paranoid schizophrenic or amphetamine psychosis, all of them had aspects of persecution, disturbing behavior, and a disturbing effect (Nicholas 181). This shows that the two conditions are closely linked, and without a clear diagnosis, one can be mistaken for the other. Describe the principal acute effects of heroin on the mind and body. (20 points) Heroin is an illegitimate opioid drug that slows the brain and the functioning of the central nervous system. Apart from its initial effects of pain relief and a sense of well being; it has acute effects on the mind and brain of the user. The principal acute effects of heroin on the brain include a slowing of the brain affecting the breathing system, which may slow down or stop (Landry 39). In addition, body temperature and blood pressure decrease, and the heartbeat become uneven. In extreme cases, the user may become unconscious or fall into a coma. Three classes of hallucinogens relate to “hallucination-producing” drugs, particular neurotransmitter systems in the brain. Describe these three categories and include one example of a hallucinogenic drug in each. (20 points) Hallucinogen is a chemical substance that can change the consciousness of a person and lead to a loss of contact with reality. Based on psychoactive ability, hallucinogens fall into three categories. These include psychedelics, dissociatives, and deliriants. Psychedelic drugs are those drugs that characteristically and consistently produce a combination of distortions of thinking, feeling, and perception (MobileReference 569). This is collectively known as the psychedelic experience. A classic example of such drugs is lysergic acid diethylamide (LSD). Dissociatives are drugs that lessen or obstruct signals to the brain. An example of such a drug is ketamine. Lastly, deliriants are considered a subgroup of dissociatives and are commonly referred to as the true hallucinogens. They contain centrally active anticholinergic substances that produce a delirium-like state leading to visual and audio hallucinations. An example of a deliriants drug is antihistamine diphenhydramine o or Benadryl. What extent of physical and/or psychological dependence with regard to marijuana smoking.
