And Adiyogi is one of the most influential thinker of his time who barely got any recognization for his work when thinkers like Aristotle appear pale in comparison to his work.
If Cannabis helps someone think clearly, why should it be banned and these alternatives popup in vaccum where the treatment of cannabis is either grey or black.
If we look at the scientific research, certain studies have claimed that aspects of creativity could be enhanced with cannabis (often based on self-reports rather than objective measurements), but those results are inconclusive at best. Cognitive impairments due to both acute and chronic cannabis use are much more well-documented. Here is a review of executive function deficits due to cannabis use:

Here is a study that found low-potency cannabis had no effect on creativity, while high-potency cannabis impaired divergent thinking: https://link.springer.com/article/10.1007/s00213-014-3749-1
If you want to argue that cannabis should be legal, I have no issue with that. But the way to go isn't to say "it's a cognitive enhancer", which it is not to the best of our scientific understanding.
What should i read from the link you posted, if it's you reading that text and accepting it as 'truth' then let me tell you, it's nothing more than your belief (ground for a shared madness or religious maybe?). It's not science, I've experience in academia, i already know how the data is cherry picked to match the narrative of the person or whoever is paying for the study. I won't accept it.
As for me, I've been using Cannabis for years, i already know what it has changed in my life. It's all positive.
