A verbose way of saying don't blame the drug, blame the shortcomings or trauma in one's life that created the impulse to abuse a drug. The article also touches on how something pleasurable doesn't become a drug until it becomes an unhealthy addiction - as long as it's used or enjoyed in moderation/with restraint, it's a medicine or tool.

If I could write that well I'd probably flaunt it, so no disrespect to the author.
