Addiction substance and

Let me press this point a bit further. I am told that it is possible for a well-supplied heroin addict to live an otherwise healthy and productive life. (It appears to be otherwise with cocaine and amphetamines.) In any case, imagine that this is so for a certain severely addictive substance,, and that in a certain culture, otherwise similar to ours, the use of S is not only tolerated but respected as highly spiritually beneficial. This culture regards the dependency on this substance, which is to say, the vulnerability to various kinds of diminished self-control, as a small price to pay for the enrichment of human life provided by S. Fortunately, S is easily obtainable, perhaps even subsidized by the society for religious reasons.

Toluene, volatile nitrites, and anesthetics, like other substances of abuse such as cocaine, nicotine, and heroin, are characterized by rapid absorption, rapid entry into the brain, high bioavailability, a short half-life, and a rapid rate of metabolism and clearance (Gerasimov et al. 2002 Pontieri et al. 1996, 1998). Because these pharmacokinetic parameters are associated with the ability of addictive substances to induce positive reinforcing effects, it appears that the pharmacokinetic features of inhalants contribute to their high abuse liability among susceptible individuals. 

The chemical composition of C. sativa is very complex and about 500 compounds in this plant are known. A complete list can be found in [81] with some additional supplementations [2,82]. The complex mixture of about 120 mono- and sesquiterpenes is responsible for the characteristic smell of C. sativa. One of these terpenoic compounds, carophyllene oxide, is used as leading substance for hashish detection dogs to find C. sativa material [83]. It is a widespread error that dogs that are addicted to drugs are employed for drug detection. A9-THC is an odorless substance and cannot be sniffed by dogs.

Given the low incidence of severe withdrawal symptoms and the modest effects on the mesolimbic dopamine (reward) system, most investigators have found that cannabis has a low abuse or addiction potential. However, it has been argued that if cannabis is a non-addictive substance, why is its use so widespread and why are there so many longterm and heavy users Finally, contrary to the evidence that cannabis can produce chronic tolerance, some regular users report that they require less drug to achieve the same high, or sensitisation (Chapter 3). Three possible explanations may account for this. First, chronic users may focus on the effects that they wish to achieve. Second, the... 

A person can meet criteria for abuse or dependence for one drug and not others, although there is concern about what has been referred to as cross-addiction. Cross-addiction means that a person who is dependent upon one substance may be dependent upon another, very similar one. An example might be a person who is diagnosed as dependent upon tranquilizers and who, you may fear, is also addicted to a similar substance such as alcohol. However, the research is not entirely clear on whether cross-addiction occurs, and I have known clients who had very specific problems with one substance who did not generalize into problems with other, similar substances. A person also may meet criteria for abuse or dependence for multiple substances generally, this is referred to more simply as substance abuse or substance dependence. 

The most commonly used therapies for anxiety and depression are selective serotonin reuptake inhibitors (SSRIs) and the more recently developed serotonin noradrenaline reuptake inhibitors (SNRIs). SSRIs, which constitute 60% of the worldwide antidepressant and antianxiety market, are frequently associated with sexual dysfunction, appetite disturbances and sleep disorders. Because SSRIs and SNRIs increase 5-HT levels in the brain, they can indirectly stimulate all 14 serotonergic receptor subtypes [2,3], some of which are believed to lead to adverse side effects associated with these drugs. Common drugs for short-term relief of GAD are benzodiazepines. These sedating agents are controlled substances with addictive properties and can be lethal when used in combination with alcohol. The use of benzodiazepines is associated with addiction, dependency and cognitive impairment. 

Cannabis carries some potential for dependence and addiction. Compared to cocaine, heroin, alcohol, and nicotine, cannabis has lesser addictive potential and withdrawal effects, but some users do develop compulsive and maladaptive use patterns that require treatment (Taylor 1998). Individuals with underlying psychopathology or tendencies for substance abuse should be particularly leery of using cannabis in the interests of avoiding compulsive use patterns. 

Nicotine is an addictive substance with rewarding and reinforcing properties. On the other hand, the autonomic responses following an acute nicotine treatment and the bitter taste of nicotine may cause aversion. This aversion may impact conditioned effects to nicotme. Rinker et al. (2008) studied possible sex differences in taste aversion mduced by nicotine in rats systemic nicotine or saline injections were paired wim oral saccharine. Although nicotme did produce a weak taste aversion, no sex differences were observed, excluding the possible contribution of the aversive properties of nicotine on sexually dimorphic responses to nicotine. The authors conclude that sex differences may arise from differences in the rewardmg properties of the drug. 

There is a misconception that drugs and medicines are quite different. The term drug carries with it the connotation of addiction, abuse and crime, but, in fact, medicines are just a subset of drugs. Drugs are defined as substances that can alter the biochemical processes in the body and medicines are those drugs that have a beneficial effect. 

Nicotine is a plant product, particularly abundant in tobacco. Plant products containing ring structures and at least one nitrogen atom are known as alkaloids. Nicotine is one of the most addictive substances known ask any cigarette smoker who has tried to quit. 

The Therapeutic Substances Act 1953 repealed the 1937Act and gave the Commonwealth control of the import into Australia and interstate trading of therapeutic substances and controlled therapeutic substances (drugs of addiction). It came into operation in 1956 and was administered by the Therapeutic Substances Branch of the Department of Health. 

Certain medicines may not be imported under the personal importation provisions, including drugs of abuse, such as narcotics, amphetamines and psychotropic substances, and anabolic substances, androgenic steroids and treatments for alcohol and drug addiction. There are also controls over certain other medicines including erythropoietin, growth hormones and gonadotrophins. 

Within this Held, most of the research and results have been focused on the effects of drug therapy on the disorders induced by alcohol, and by the abuse of opiates. For a broader discussion of substance abuse see Chapter 18. In all instances of alcohol or drug abuse the first objective is to wean the patients from the addictive substance, treating or preventing the effects of withdrawal for those substances which cause physical dependence (alcohol, nicotine, opiates, caffeine, certain psychotropic agents such as benzodiazepines, possibly antidepressants). The second phase is the prevention of recurrence or relapse, which relies on a combination of social support, psychotherapy, and pharmacotherapy where available. In this respect, alcoholism is exemplary.

Psvchopharmaceutieals are medications that can affect the behavior and subjective state of man and are used therapeutically on account of these psychotropic effects. Apart from psychopharmaceuticals, there are man) other substances with psychotropic action, such as alcohol, nicotine, cocaine and heroin, which are characterized as social or addictive products and have no generally recognized therapeutic applications in Western medicine. Analgesics and members of other drug classes also have direct or indirect actions on subjective state and behavior but are not considered to be psychopharmaceuticals because they are not used primarily for their psychotropic effects.
