There's no evidence to support the use of the supplements in the Thomas recipe. The Thomas recipe for treating opiate withdrawal is a collection of medicines and supplements, so each ingredient requires independent evaluation; however, medical supervision is essential when dealing with withdrawal from opiates, which can be deadly.
The main ingredient in the Thomas recipe, Valium or another benzodiazepine, might be appropriate for some. While benzodiazepines can help with insomnia and muscle aches, these medications are not a standard treatment for opiate withdrawal symptoms, and their potential for addiction makes them dangerous to use without appropriate monitoring. When used under medical supervision, methadone and other drugs are considered safe and effective at relieving withdrawal symptoms.
