Drug control is also difficult because of its wide spread use; the organization of producers; the number of smugglers and traffickers; and the amount of money involved. Police are frequently out-armed and out-spent. The judicial system is subject to bribes, intimidations and murders. Attempts to arouse public opinion by newspapers or concerned groups and individuals result in bombings, kidnappings and killings. Enforcement agencies are often at odds with each other because of different concerns and methods.
In addition, different national control procedures may vary in the degree of restriction and supervision of legal drug production. The effects, especially the long-term effects of drugs used for medical purposes, both with and without prescription, are not necessarily fully explored before the marketing and use of the drug takes place ([eg] thalidomide, bromide hypnotics, barbiturates). Lack of public information, and even of medical information on the properties of drugs, may lead to unwittingly harmful use under certain circumstances or harmful combination with other drugs. It is said that governments have become so nervous of upsetting the powerful multi-national drug companies (and of the risk that they might move their factories elsewhere) that they are reluctant to impose restrictions on the industry. Control of toxic substances such as solvents, used daily for domestic and industrial purposes, is very slight compared with their harmful potential. Such drugs constitute an occupational or medical hazard and may be abused in the same way as illicit drugs. Inadequate attention may be given to the intoxicating and addictive effects of alcohol, nicotine and caffeine.
Drugs are processed in a variety of ways and in a variety of locations. Marijuana is usually dried or used to produce hashish by the grower. Traditionally opium products were produced by middle men associated with big international smuggling and trafficking organizations but increasingly being processed by more local organizations which, in turn, are establishing their own smuggling networks. Cocaine products are, for the most part, manufactured by South American syndicates which control everything from growers to traffickers. Drugs used for medical and veterinary purposes are manufactured by legitimate businesses. Designer drugs such as ecstasy may be manufactured by bath tub chemists in any local neighbourhood.
Although severe sentences have discouraged causal users of marijuana and cocaine this has ensured that the supply and distribution is increasingly concentrated in the hands of professional criminals. Mandatory sentences for offenders have overstrained the courts, prisons and police. They have also increased the murder rate, because criminals often kill potential informers and witnesses.
2. Too many legislators do not ask if new measures will work, they ask only if the measures are restrictive enough. Punitive, coercive, and prison-based drug treatment programmes are still the standard, yet they have given no signs of being effective. Prison is not a quick and easy solution to the drug problem; it is no solution at all.
