The interpretation of drugs in your dreams depends on the relationship you have with drugs in your daily life and whether they are doctor prescribed or not. If you are a drug user, then the drugs are an extension of what you normally do, and you need to look at the other details of your dream to get a good interpretation. However, if you use drugs rarely or never, then this dream could represent a need to get well, to escape from daily stress, and a desire to get quick relief. The drugs could be suggesting a need for healing and getting in balance. Your unconscious mind may be suggesting outrageous things in hopes that you get the message to “have fun, dream dreams, and get out of your own head!” Please keep in mind that the purpose of dreams is to raise our consciousness and to assist us in having better lives. The message in the dream about drug use is most likely not encouraging you to use drugs but it may represent a need to feel better or get better.
