It has long been known that ingesting certain substances, particularly herbal derivatives, can alter perception. These can induce anything from a state of euphoria to a distortion of reality. This, however, can be dangerous - without knowledgeable supervision - since it is like using a crowbar rather than a key to open a door to the psyche. We may be attempting to avoid reality and drugs can enable us to do this. They can also be a healing agent in restoring balance. In dreams, to be given drugs by a qualified person signifies that we have accepted someone elses greater knowledge. To be sold drugs illegally indicates that we are prepared to take unnecessary risks. When drugs appear in a dream - whether self-administered or not - this suggests that we may need external help to enable us to change our inner perceptions. To be taking drugs suggests we feel we have relinquished control of a situation in our waking lives and are having to rely on external stimuli. To have an adverse drug reaction in dreams could mean that we fear madness. To be given drugs against our will indicates that we are being forced to accept an unpalatable truth.
