They can be powerful for breaking addictions whether that's food, sex, alcohol, tobacco or other, however they are themselves addictive for the ego mind because of the vibrant, picturesque entertainment quality experience they provide. That's to say, there's a line an individual must determine of when there is healing benefit from the practices vs. when they are addicted or have become dependant on them - dependant to clear energy and get relief from blocks/energy stagnancy that a psychedelic will only temporarily clear or let flow - when instead different work or practices are required. There are edge cases of course where, say with people who have chronic pain, where micro-dosing can allow energy to flow more easily and give relief where otherwise it can't come from other means.
