War on drugs is for example a war on people, usually the poor but not always. This war is not even fought with officers in an army but with a special law enforcement agency. Wars typically were fought for religion, resources, land, or pride itself. The DEA is very corruptible and probabbly is in some respects.
The DEA is just a facet of the corruption; they are a scapegoat for those who truly make the calls: The Department of Health and Human Services. The enforce the laws, and take the brunt of the criticism for the harm they cause and the idiotic laws they enforce, whilst they really have no say in them. Also, the laws are made so that they take FOREVER to change. Easily the GREAT majority of US citizens support complete legalization of Marijuana, yet every attempt to even decriminalize it has taken years, and years, and years, and in the end failed.
This war is more then likely kept together for the sake of ************** companies, whom profits are above any other industry. Drugs are drugs, they all have their effects and negative responses to their use. Some illegal hard drugs are obviously very harmful, like crack, meth, pcp, whereas heroin use to be used as a painkiller, cocaine was used for various purposes, hallucinogens have been used in cultures all around the world for many years and marijuana plants have so numerous amounts of usage its astonishing.
The real problem with a war on drugs is that it is only an Idealist concept of what is and isn't acceptable for you to choose to put into your own body.
That is not the purpose behind the War on Drugs. That's just the message they portray to society, that they are fighting drug abuse to protect society; that is truly very far from the truth. It isn't just "more than likely" kept together for the sake of corporations; it's an irrefutable fact that the War on Drugs is fought almost solely to enrich drug companies, who, through being lobbyists, in turn, enrich the politicians they command.
Proof of that: Marijuana was originally scheduled with no knowledge of its abuse and addiction potential. Immediately following its scheduling, the government funded a study to determine its abuse and addiction potential, promising to remove it if there was found to be no addiction potential (as is legally required of a schedule I, II, or III substance; schedule I requiring extremely high addiction and abuse potential). That study came back with results saying Marijuana and it's psychoactive constituents were not addictive at all, and that it had very low abuse potential. The administration completely ignored the study, and to this day Marijuana remains a schedule 1 substance (illegally). Also, it is unconstitutional for any substance to be controlled without an amendment, as had to occur for Alcohol to be banned. And you know what's more? Many of the active psychotropics in Marijuana are potential extremely effective treatments for brain cancer, and other types of cancer to a lesser degree, yet the laws against it greatly inhibit the progression of research, research which likely could have saved thousands by now. Why? Because if Marijuana was legal many of the (toxic and addictive) pain medications currently mass-manufactured would become obsolete, losing the drug corporations billions.
Secondly, LSD is an extremely highly penalized schedule 1 substance without any addiction potential either, along with the other main psychedelics: Psilocybin, Mescaline, 5-MeO-DMT, DMT, Ecstacy, and all of their analogs. The minimum federal sentence for LSD possession is 5 years in prison. Aside from the amphetamines, all of these drugs are completely non-toxic to humans. I think it is rather obvious, due to the nature of these drugs, the reason they are so illegal: they cause people to question, to wake up and dissent. They were (illegally & unconstitutionally) made illegal in association with an "attempt to overthrow the government" (the children's revolution of the 60s and 70s). In other words: these drugs are so illegal in order to pacify and control the people. Even more, these drugs are some of the most therapeutically beneficial substances known to man. LSD & Psilocybin are the two most powerful treatments for one of the most painful human illnesses (cluster headaches); they stop the pain, and interrupt the cycle of headaches, preventing them from occurring in the future. And all psychedelics are extremely potent and helpful tools in psychotherapy, with nothing else that even comes close to the benefits they can gleam. Yet there is no accepted medical use of any psychedelic.
That is the real problem with the War on Drugs.
