Can't tell you how true this is. Getting someone high is the first step to breaking someone out of an ideology, cult, religion, worldview, etc. It shifts their perspective in a way that makes them understand, for the first time, that there's more than one perspective, it breaks them out of philosophical solipsism based on assumptions and naivety.

Now, they don't need to be high 24/7 for that to be true. Just one or two shroom, acid or weed sessions will usually open a bit of a third eye in most healthy proles. Unfortunately, of late the wonders of these drugs have been abused by the unhealthy and by our class enemies in distorted ways like "improving productivity" with micro-dosing acid (blegh) or dulling ourselves and self-medicating depression.
