So  agree. These substances are just "escape" drugs.  Enlightenment comes from introspection from within  to understand one self and  to learn to respect and love oneself as one stands. That one is worthy of being love and that "imperfections" are ok.  Can never find the solution from  outside influences.  Change within  or nothing will ever change.  Changing friends, surroundings,  or taking  substances, etc will not do the trick. You can't escape from you.  "You" must be the focus  of any change or understanding. It is the origin of everything.  Without you, there is no reality.
