" Intoxication could be viewed as psychic masturbation. Masturbation could be defined as trying to do something when you don't have everything needed to do it. Contacting the subconscious realms of significance without our full equipment is like making love without a partner. Not only is it less physically satisfying, it bypasses the emotional and spiritual dimensions of relationship. One can understand the many reasons why people do it: loneliness, impatience, narcissism. Like intoxicants, masturbation creates a tension between the fantasy and the actuality. It leaves people askew and ultimately crippled.
Can psychoactive substances ever yield psychological or spiritual benefit? A qualities "yes" suggests itself here. An experience produced by external substances may give enough of a taste of higher being to motivate someone toward awakening that state on a more permanent and stable basis, especially if the person has not already been exposed to the mature spiritual guidance that certain traditions could offer.
It is important to keep in mind, however, that the shift of perspective offered by certain drugs can also be accomplished through various other means, one of which is contact with someone who has attained higher being. While such an experience may be a bit less dramatic than a drug experience, it is less likely to cause psychological imbalance. On the other hand, such imbalances can also be caused by teachers with limited knowledge who induce certain states in their students that may, if indulged in, make them less fit for ordinary life and less capable of reaching completion."
