Psychological dependence cocaine

The antipsychotics do not produce a ciassic withdrawai syndrome of the type seen with barbiturates or opioids nor do they produce psychological dependency, as seen with psychostimuiants (e.g., cocaine, amphetamine). Addicts and patients both dislike these drugs and do not spontaneously increase their dose. Indeed, they are more likely to discontinue them without medical advice. 

Under the Controlled Substance Act, cocaine is a Schedule II drug. This means that cocaine has a high potential for abuse and that abuse may lead to severe physical and psychological dependence. It also means that cocaine has accepted medical uses with severe restrictions. The only legal use of cocaine in the United States is as a local anesthetic. 

Ritalin is a mild stimulant. On the contrary, the studies found that Ritalin, although effective in treating the symptoms of ADHD, shows no clear long-term improvement on users and can have dangerous effects on health, including death. Because the effects of Ritalin on humans are virtually identical to those produced by cocaine, amphetamine, and methamphetamine (speed), the researchers noted that its abuse liability is high and can lead to marked tolerance and psychological dependence. 

Tolerance to the mood-altering effects and psychological dependency develop as with cocaine, and symptoms of withdrawal appear when the drug is stopped. Laboratory animals who have learned to self-administer amphetamines have been observed to choose drugs instead of food and water they die from exhaustion in their frantic efforts to feed their high. —... 

Like amphetamine and cocaine, abuse of MPH [Ritalin] can lead to marked tolerance and severe psychologic dependence. The pattern of abuse is characterized by escalation in dose, binge use followed by severe depression, and an overpowering desire to continue to the use of the drug despite negative medical and social consequences. The abuser may alter the mode of administration from oral use to intranasal or intravenous use to intensify the effects of the drug. (p. 35)... 

In an interview study (Robson and Bruce 1997), the dependence potential of various street drugs was assessed in 201 problem and 380 social users of heroin, cocaine or amphetamine using the well-validated Severity of Dependence Scale (SDS). Scores (maximum = 15) in the problem group were 12.9 for heroin, 9.6 for other opioids, 6.1 for amphetamine and 5.5 for crack cocaine. All of these scores were consistent with findings in other studies. Cannabis SDS score was 2.6 and comparable with those of LSD (3.1) and ecstasy (1.3), two drugs that are generally not associated with physical or psychological dependence. In the parallel sample of social users, the cannabis SDS was similar at 3.4. 

Cells can also recover from the signal for the fight or flight reaction by taking hormones that they have released back up into themselves. Cocaine interferes with the reuptake of adrenalin by cells in the cortex of the brain, thus intensifying the effects of adrenalin and producing a sense of euphoria and (sometimes) hallucinations. Cocaine use leads to psychological dependency and can cause convulsions, respiratory failure, and death. 

Dependence and withdrawal can occur with all of the stimulants. Cocaine is one of the most strongly reinforcing drugs in self-administration paradigms in animals and also has a psychological withdrawal syndrome. A typical pattern of withdrawal includes a ravenous appetite, exhaustion, and mental depression, which may last for several days after the drug is withdrawn. Because tolerance develops quickly, abusers may take large doses, compared with those used medically, for example, as anorexiants. 

Schedule II—The drug or other substance has (1) a high potential for abuse, (2) a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions, and (3) abuse of the drug or other substances may lead to severe psychological or physical dependence. Examples cocaine, PCP, morphine, fentanyl and meperidine, codeine, amphetamine and methamphetamine, Ritalin . 

In contrast, some drugs of abnse prodnce intense craving and are highly addictive bnt do not prodnce physical dependence. The absence of physical dependence indicates the relative lack of physiological withdrawal. This is not synonymous with meaning that discontinuation of these componnds may not be psychologically nncomfortable. Two examples are marijnana and cocaine. One need only look to the recent crack epidemic to see evidence of the way these substances can destroy lives, bnt they do not produce tolerance or risk of withdrawal to the same extent as alcohol or heroin. As a result, we would say that the daily crack or marijuana user meets the dehnition of substance dependence bnt does not exhibit true physical (or physiological) dependence. 

Schedule II Substances with a medicinal use but also a high potential for psychological or physical dependence. A written prescription is required for use for example, morphine, cocaine, and oxycodone. 

Therapeutic uses Factors that limit the therapeutic usefulness of amphetamine include psychological and physiological dependence similar to those with cocaine, and the development of tolerance to the euphoric and anorectic effects with chronic use. [Note Less tolerance to the toxic CNS effects (for example, convulsions) develops.]...
