I enjoy reading opinions on this matter, i do not agree with most of what you have said and believe you have a somewhat cynical attitude. But regardless, if you compare psychedelics to alcohol, you are most definitely not educated about the reactions that take place in a humans body on either a psychedelic substance or alcohol. There is no comparison, and even though i agree on few things conveyed in this article, i believe that statement has no merit. I invite you to look up the many studies that have been released recently detailing the profound psychiatric implications psychedelic substances carry, and to maybe re asses, at the very least that specific statement. This is obviously not a scientific paper you have wrote and carries alot of personal emotion within it, but that statement is simply not true. And also, there are political reasons that these substances are illegal, and remain illegal. It is not cocaine or heroin, and these substances procure a potential to enhance the sense and broaden the brains capacity for connectivity. If you feel that statement is simply not true, this has been proven in laboratory settings, in double blind studies. 
Have a wonderful day and thank you for the article! Much love
