Drug use can mimic higher states of consciousness but the difference is actually night and day. In some cultures (such as the Amazonian shamans' use of ahayhuasca), certain substances (along with disciplined preparation and purification) purportedly assisted in quantum leaps in consciousness. To use that or similar examples as a pretext to indulge in psychedelics is a huge trap on the Path. Nothing is for free and use of drugs drains one's pranic body and dries up cerebral spinal fluid and ojas (the lubricating energy conducting, fluid of the spine). This inhibits the process of Kundalini Rising. Authors such as Carlos Castaneda, Terrence McKenna, and Timothy Leary,  whose writings are very enticing, claimed that psychedelics could be used to shatter the boundaries of illusion. Their writings don't really mention that the use of drugs is not healthy and there is a price to be paid. What we do defines us and has a bearing on what becomes of us. Bottom line: we feel that drug use is a complete dead end and that Kundalini Yoga is a billion times better.  

We do feel that, when absolutely necessary, some drugs can be a godsend for the relief of pain. Many people swear that marijuana, when used medicinally, has therapeutic advantages over everything else they've tried. We can't argue with the necessity to ease one's suffering, but we do encourage everyone to get to the root causes for whatever is going on, and to honestly assess whether there is a physical or psychological dependence on anything. If so, set an intention to create a relationship with Energy and Essence. The need for stop gaps will fall away. It may take a day, or it may take 10 years, but if you keep your intention strong, you will be victorious. Draw upon that inner aspect which is already complete, fulfilled, and blissful.
