Illicit drugs morphine

The toxicological or cumulative effect of illicit drugs on the ecosystems has not been studied yet. Moreover, their fate and transport in the environment is to a big extent still unknown. Due to their physical-chemical properties (octanol-water partition coefficient, solubility, etc.) some of them, such as cannabinoids, are likely to bioaccumulate in organisms or concentrate in sediments whereas the rest, much more polar compounds, will tend to stay in aqueous environmental matrices. However, continuous exposure of aquatic organisms to low aquatic concentrations of these substances, some of them still biologically active (e.g., cocaine (CO), morphine (MOR) and MDMA) may cause undesirable effects on the biota. 

The analysis of codeine, morphine, 6-monoacetylmorphine (6-MAM, a metabohte of heroin), and cocaine is important for many toxicology labs to determine illicit drug use. When analyzing opiates in urine samples, frequently the matrix chosen for drug screening, the conjugated metabolites must be hydrolyzed however, this process can break down 6-MAM (Christophersen et al., 1987). These compounds can be derivatized to increase sensitivity, and both BCD and NPD are used for these assays. Derivatizations used include reaction with N-methyl-N-trimethylsilyltrifluoroacetamide followed by GC-FID (Lin et al., 1994) or with N,0-bis(trimethylsilyl)trifluoroacetamide (Christophersen et al., 1987 Lee and Lee, 1991), PFPA (Christophersen et al., 1987), or heptafluorobutyric anhydride (HFBA) followed by GC-ECD. All these methods show good sensitivity and selectivity. 

Heroin, the diacetyl derivative of morphine, is the most important illicit drug derived from the opium poppy. Together with heroin and its metabolites, other synthetic (e.g., methadone, tramadol) and semi-synthetic (e.g., buprenorphine) opioids have been quantified in different biological fluid using HPLC. 

Methadone is given orally (different from the usual means of abuse), and thereby also substitutes for the paraphernalia that accompany illicit drug use. Methadone helps relieve the craving for more drug and delays the appearance of withdrawal symptoms as long as it is in the body. Doses are gradually decreased. If the dose of morphine that was abused is known, then 1 mg of methadone can substitute for 4 mg of morphine. Otherwise, a dose of 10-50 mg a day is generally used, and can be reduced by 20% per day.

In a review of 239 cases of heroin-related drug deaths between 1997 and 2000, 18 deaths were associated with non-intravenous administration (49). The median morphine concentration in these non-injectors was 0.05 mg/g and this was significantly lower than in injectors (2.3 mg/ g). There was concurrent use of alcohol, other illicit drugs, and/or pharmaceutical formulations in 17 of the 18 cases.

Exceptions to this last observation are encountered when the colored materials happen to be present in the same phase where, because of their excessive absorbances, the signal-to-noise ratio is decreased. This kind of complication was successfully handled in direct analytical assays devised for lysergic acid diamide (LSD)f and phencyclidine (PCP) in illicit drugs spiked with intensely colored dyes for L-cocaine, morphine, and methadone in the pharmaceutical product commonly referred to as Brompton s cocktails and for D-pseudoephedrine in children s Sudafed. ... 

Cannabis is by far the most commonly used illicit drug. Most people who abuse hard drugs such as heroin also abuse cannabis. Tetrahydrocannabinol (acid and A -metabolite) is regulated in the German traffic law (see Table 7-1), and amphetamine, opiates (morphine) and cocaine (as benzoylecgonine metabolite) are also mentioned. 

Heroin production Morphine free base is refluxed in acetic anhydride for 5h. The mixture is allowed to cool and is neutralized with sodium carbonate causing the precipitation of crude diacetyl-morphine free base, the illicit drug in heroin samples. Monoacetylation of morphine and acetylation of any codeine present also occurs. The crude product is purified by dissolving in acidified water containing charcoal and the free base precipitated by the addition of sodium carbonate. If the hydrochloride salt is required the free base is dissolved in acetone and the product precipitated by the addition of hydrochloride acid. 

An area of pharmacology that holds immense interest and importance is illicit drug detection. A commercial RIA kit has been used in an Italian laboratory to detect morphine, cocaine, and ecstasy constituents in extracts of hair samples. This diagnostic strategy has been applied to determine whether former users of illicit drugs are fit enough to obtain a driving Hcense. 

CE is also useful in forensic toxicology laboratories to screen urine for drugs of abuse such as opiates, barbiturates, benzodiazepines, amphetamines, morphine, etc. and also for screening postmortem fluids for illicit drugs or elevated levels of legal drugs. When coupled to MS, CE is a powerful tool in the confirmation of positive results. 

An interesting recent example (Castiglioni 2006) describes an LC-ESI-MS/MS method for the determination of the illicit drugs cocaine, amphetamines, morphine, cannabinoids, methadone and some of their metabolites in wastewater (both treated and untreated). Quantitation was achieved in the low ng.L range, with overall variability <10%. Cocaine and metabohtes, amphetamines, morphine and metabolites, methadone and its main metabolite, and 11-nor-9-carboxy-A9-tetrahydrocannabinol (the main metabolite of tetrahydro-catmabinol), were aU measured in significant amounts in influents and effluents of two wastewater treatment plants, indicating possible environmental risks to pubhc health. 

Drug interactions morphine has additive effects when used in conjunction with alcohol, other opioids, or illicit drugs that cause central nervous system depression because respiratory depression, hypotension, and profound sedation or coma may result. 

Clenbuterol was detected in 12 of 106 postmortem cases in the USA in which the cause of death was attributed to illicit drug use [114 ]. In each case heroin use was either confirmed by the presence of 6-acetylmorphme or strongly suspected by the presence of morphine with a history of heroin abuse. The authors suggested that one should test for clenbuterol when treating a suspected heroin user with an atypical presentation.
