It was referring to the difficulty for a religious person to leave behind his belief.
Like the opium addict, the religous one think he “needs” religion.
Also, drugs has an evident ALIENATING and EVADING effect, taking the addict to an abstract “world of pleasure and delussion”… while tripping, the person is unable to recognize reality, criticize it and change it.
Distanced from reality and from others sufferint the same oppresion facilitate the control of masses by the eocnomical elite.
Evading from a harsh reality is the cowards or political uneducated way.
