Profound benefits of Transcendental Meditation not due to 'placebo effect': Expert researcher

I find that sometimes people wonder whether the various benefits that meditators say they experience after learning Transcendental Meditation are due to the ''placebo effect.''
Here's an interesting response to that question from researcher Dr. David Orme-Johnson:
''Placebo effects are powerful, but they are psychological, short-lived, and decay over time. It is generally understood in the scientific community that a treatment effect is not due to placebo if it can be demonstrated by objective measures as having long-term effects.
In numerous studies the Transcendental Meditation technique has been found to produce long-term effects—ones that grow stronger the longer a person regularly practices the TM technique.
Like placebos, the TM technique can produce substantial short-term effects. This has been shown in a number of studies where TM has been found to substantially reduce anxiety in as soon as the first two weeks of practice.1 But some placebos do also. However, related research on the TM technique also shows distinctive physiological changes that naturally produce a basis for long-term growth, such as sustained reductions in anxiety.1-4
Here are some examples of the kinds of physiological changes that research has found:
1. The physiology of the transcending process through the TM technique is the opposite of the physiology of anxiety, indicated by reduced respiratory rate, muscle tension, reduced plasma cortisol, and increased autonomic stability,5-11 and increased coherence of brain functioning as indicated by increased EEG coherence.12-14
2. The reduced physiological correlates of anxiety are also sustained outside of meditation in day-to-day life, as seen in 50% less reactivity to stress in those who have been practicing TM for five months,15 in lower cortisol levels being sustained after meditation,16-18 and in increased EEG coherence during stressful tasks after meditation.19
3. Randomized controlled trials show that TM practice increases resilience—improved logical reasoning, reaction time, practical intelligence, and creativity—all important capabilities for effectively coping with threat and overcoming anxiety.4,12
4. Longitudinal studies have found that TM practice reduces anxiety-related behavioral problems, such as prison recidivism,20-22 cigarette smoking, alcohol and drug abuse,23 and reduced suspensions in schools.24
5. In several federally-funded studies by the National Institutes of Health, TM practice reduces anxiety-related diseases, such as high blood pressure,25-28 and other aspects of coronary heart disease,29 including heart attacks, strokes and death in a 10-year study.30
6. Finally, whereas placebo effects are short-term, TM practice produces long-term reductions in anxiety, as measured by psychological tests.1-4 After all, feeling better and higher quality of life is the subjective significance of all the physiological benefits.
These illustrate how broadening our perspective to include a wide range of related objective measures and studying their long-term effects can help us to assess whether a treatment effect of a psychological outcome is anything other than a placebo.''

David Orme-Johnson received his BA in psychology from Columbia University in 1963, and his MA, Ph.D. Psychology from the University of Maryland. Dr. Orme-Johnson is recognized as a leading expert in research on meditation. He was one of the first scientists to research the effects of meditation on the elimination of stress. His pioneering research in this area was first published in 1973 in the journal, Psychosomatic Medicine. To date Dr. Orme-Johnson has published over 100 papers on the psychological and sociological effects of meditation. Dr. Orme-Johnson has presented his research at over a hundred scientific conferences in 37 countries, including presentations to the United Nations on four occasions.
