Many people crudely think that all illegal drugs are illegal because they are physically dangerous to the user. That is not the case. Different substances have been made illegal at different times and for different reasons.

Psychedelics are commonly non-toxic and pose no physical threat even at extreme doses. Most of these substances are not even possible to overdose to the degree that they would be life threatening. But there is one real health risk and that is to the user’s mental health.

Psychedelics have the unique capacity of unlocking the doors of the unconscious mind. They can release what has been carefully locked away and repressed. This is of course what makes them such powerful therapeutic tools, but if the person isn’t open to taking care of what comes up the experience can be quite traumatic. The same goes for other kinds of therapy, meditation and contemplation.

If you aren’t ready to meet what you have repressed you shouldn’t do or take anything that will uncover what you have buried.

It is still a debate and an intriguing one.
