That isn't the point that was made, despite the fact that it's what he had said to preface the rant.
Expanding your mind? No, drugs aren't going to do that. Rather, it temporarily messes with thinking and perception. This can open new avenues for creativity, because much of human creativity is inspired from experience. The same goes for pretty much everything human. We learn from experience, even if it's not an experience of our own. The more experiences you've had in life, the more ways you have to look at the world. And while the topic is largely centered around hallucinogenics, which heavily alter perception, I'd say the same goes for most drugs. Yes, they can effect your outlook on life and your perception of the world, as can most any kind of human experience.
I agree with Destinizish here. While drugs can open one's mind to creative and original thinking, they do not necessarily "expand" or improve the overall state of one's mind.
I used to be a mild user of certain hallucinogenics, but permanently quit after about 10 experiences total. I've tried Salvia Divinorum, Dimethyl Triptomine, Psylocybin mushrooms, and Amanita Muscaria.
When I used Salvia (which I later found out to be a drug that is ideally ingested through chewing fresh leaves, not by smoking "extract"), I experienced a violently intense series of visuals that took me back to my childhood home while including the sensation of being "guided" by two spectral beings. The experience was interesting, but I feel like I ultimately gained very little from it other than a scare and some pretty things to remember.
DMT gave me a very interesting view on my own life and changed my perspective on things a bit, but I still feel that the risks ultimately outweigh the benefits of using it. Of all the drugs I've tried, it is definitely the one I feel holds the greatest potential for personal gain, but it is dangerous when used by those uneducated in its potency and effects, and it is quite illegal.
Psylocybin and Amanita Muscaria were both "high-like" experiences that gave me no insight or knowledge whatsoever, but simply made me feel varying amounts of good and bad while being in an inebriated state of mind. Amanita gave me a good night's sleep, but that's about all I say in its favor. It was otherwise quite weak and ineffective. Psylocybin gave me a roller coaster-style trend of emotions, while colors and patterns were more interesting to look at.
All in all, the only drug I can ever see myself ever doing again is marijuana, and I don't plan on using that more often than once a month at most. The experiences and sensations of drugs don't appeal to me now that I've tried a few, and I value the health of my mind and body over a temporary high or awe-inspiring experience with no real lasting value.
