Q: Do alcohol or drugs affect Reiki energy?
A: No. They do, however affect your ability to sense the energy strongly and make intuitive decisions with a clear mind. Just as your common sense and judgment are affected by the use of such substances, your decision making process is affected also. Would you go to a doctor or alternative health practitioner for a treatment if that person had had a few drinks at a party first? If not, why would you treat someone with Reiki if you’ve had a few?
An exception is that if there is an emergency, you could provide Reiki energy and trust that it would work to assist the victim until paramedics could arrive.
So the energy will still flow, but 1) you may not sense it with the same intensity or nuances as you would if you were grounded and clear, and 2) you might not use your common sense regarding communicating about the energy as you would otherwise.
Regarding the first item, sensing the energy, you may feel some sensations that are part of the reaction to the alcohol or drugs, and think they are the energy. Or more likely, you may not be able to feel the same subtle energetic sensations of the Reiki because they will be masked by the effects of what you imbibed.
For instance, regarding the second item above, common sense, if you sense during a healing session that the person you are sharing Reiki with has a blocked second chakra, you may or may not choose to discuss with the person what this could relate to. The second chakra being blocked could relate to an issue with sexuality, for instance (as well as many others). A Reiki practitioner needs to be sensitive and use good judgment when sharing intuitive information and communicating with the client. Any substance which affects one’s ability to make sensitive and sensible choices may also impair one’s sense of judgment over these decisions. You wouldn’t want to hurt someone’s feelings or make that person uncomfortable by losing your professional boundaries due to being chemically impaired.
So yes, the Reiki will still work if you’ve had alcohol or drugs. The question really is: should YOU?
