The Greek word rendered "sorceries" in this verse is pharmakia or pharmakeia; according to Vine’s Expository Dictionary of New Testament Words, pharmakia
...primarily signified the use of medicine, drugs, spells; then, poisoning; then, sorcery...
...In sorcery, the use of drugs, whether simple or potent, was generally accompanied by incantations and appeals to occult powers, with the provision of various charms, amulets, etc., professedly designed to keep the applicant or patient from the attention and power of demons, but actually to impress the applicant with the mysterious resources, and powers of the sorcerer.
(W.E. Vine, An Expository Dictionary of New Testament Words, 1940)
In the late 1950s-early 1960s, hallucinogenic drugs such as LSD were being promoted as useful in treating mental illness. Fifty years later, here we go again. According to The New York Times of April 12, 2010:
Scientists are taking a new look at hallucinogens, which became taboo among regulators after enthusiasts like Timothy Leary promoted them in the 1960s with the slogan "Turn on, tune in, drop out." Now, using rigorous protocols and safeguards, scientists have won permission to study once again the drugs’ potential for treating mental problems and illuminating the nature of consciousness.
...Researchers from around the world are gathering this week in San Jose, Calif., for the largest conference on psychedelic science held in the United States in four decades. They plan to discuss studies of psilocybin and other psychedelics for treating depression in cancer patients, obsessive-compulsive disorder, end-of-life anxiety, post-traumatic stress disorder and addiction to drugs or alcohol.
The results so far are encouraging but also preliminary, and researchers caution against reading too much into these small-scale studies. They do not want to repeat the mistakes of the 1960s, when some scientists-turned-evangelists exaggerated their understanding of the drugs’ risks and benefits.
Because reactions to hallucinogens can vary so much depending on the setting, experimenters and review boards have developed guidelines to set up a comfortable environment with expert monitors in the room to deal with adverse reactions. They have established standard protocols so that the drugs’ effects can be gauged more accurately, and they have also directly observed the drugs’ effects by scanning the brains of people under the influence of hallucinogens.
Scientists are especially intrigued by the similarities between hallucinogenic experiences and the life-changing revelations reported throughout history by religious mystics and those who meditate.
If you're wondering how this ties in with spiritual deception in the days prior to the return of Jesus Christ, here's a passage from the article that is particularly revealing (emphasis mine):
The work has been supported by nonprofit groups like the Heffter Research Institute and MAPS, the Multidisciplinary Association for Psychedelic Studies.
"There’s this coming together of science and spirituality," said Rick Doblin, the executive director of MAPS. "We’re hoping that the mainstream and the psychedelic community can meet in the middle and avoid another culture war. Thanks to changes over the last 40 years in the social acceptance of the hospice movement and yoga and meditation, our culture is much more receptive now, and we’re showing that these drugs can provide benefits that current treatments can’t."
Researchers are reporting preliminary success in using psilocybin to ease the anxiety of patients with terminal illnesses. Dr. Charles S. Grob, a psychiatrist who is involved in an experiment at U.C.L.A., describes it as "existential medicine" that helps dying people overcome fear, panic and depression.
"Under the influences of hallucinogens," Dr. Grob writes, "individuals transcend their primary identification with their bodies and experience ego-free states before the time of their actual physical demise, and return with a new perspective and profound acceptance of the life constant: change."
