I assume by drugs you mean recreational as well as the other types people use to escape

Like you I have no experience with taking such drugs

I have read that in some practices like shamanism hallucinogens are sometimes used to amplify “spiritual/dream” experience however always under guidance. I suspect such experiences are not that helpful to those without training or guidance.

For example, I have a friend who had experiences of remembering a past life. She was very excited about it however she didn’t use the experience to help her in the present… actually, the experience lead to an inflation of the ego as well as the temptation to escape into it.

My own view is that a good understanding of symbolic language/images, the problem of opposites/dualism, and the shadow are required to unpack such experiences if your going to learn something from them.

Actually, I found that opening myself up to symbolic language has allowed me to experience the ‘oneness’ and ‘Love’ that many who used drugs have said they experienced. No drugs required
