Any culture that has used Cannabis as an intoxicant for thousands of years, appears “crazy” to Western man, whether Hindu, or Muslim.
They look just about what we would think a culture would look like, if it smoked Hashish and pot for a thousand years.
Western man has always wanted to stay away from it’s use as an intoxicant, from the time of Greece, to the centuries of the Crusades, up until the 60s today.
Middle Eastern culture was very advanced until the war cult of Islam took over. Some of the most advanced civilizations in history thrived there for thousands of years with cannabis. Then all innovation stopped under Islam so I would say that is the more likely cause.
The Chinese and Indians have used Cannabis for even longer than middle easterners. It was common in China until the communists and remains defacto legal in India today.
Cannabis always was and remains very popular with middle Eastern Jews. It is defacto legal in modern Israel and people smoke openly in the streets and hookah bars.
