I'm not saying that white sugar is perfectly healthy, but that article is poorly written and worstly researched, with plain FALSE information to convince you that you should buy his natural products, full of african biochemistry and chinese wisdom. Crappy bullshit.
Sadly many things we eat are as bad as that article say, but white sugar is not among them. The problem with white sugar is that some diets have a heavy intake of refined white sugar and that excess is the problem.
On the other hand, I do maintain that cannabis is a natural drug, but it's a drug. Smoking it has effects on you (or nobody would smoke it) and it's not inocuous. It is bad for your lungs and THC has long-term neurological effects as almost any psychotropic drug has.
And then again, if tobacco is legal I don't know why cannabis shouldn't be. A friend of mine used to say "everyone has the right to fuck up their own body as they want".
Wound up, can't sleep, can't do anything right, little honey / Oh, since I set my eyes on you. / I tell you the truth. I can't get it right / Get it right / Since I met you...
