LOL - when you make a serious argument, rather than presenting silly anecdotes, you can reasonably expect serious responses... ;)
You would probably be amazed at the sheer number of software systems used every day by people all over the world which were written, every single line of code, while stoned on cannabis. This not to include the articles, fiction, poetry, commercial drawings, commercial ads, legal briefs, architect plans and draft drawings for machinery likewise crafted while stoned.
You evidently have absolutely no idea what you are talking about, no clue to objective results of the use and effect of cannabis, and one emotional exerience to base your objection on. Like the poster above asked, did you hang yourself in your jail cell, too?
