Cannabis has been popular in the Sub-continent since the beginning of recorded history and is often taken as a drink. Nuts and spices, like almonds, pistachios, poppy seeds, pepper, ginger and sugar are combined with cannabis and boiled with milk and this mixture is called "Bhang". Bhang is about the strength of Western marijuana. Other preparations of cannabis include ganja and charas. Stronger than bhang, ganja is made from the flowers and upper leaves of the female plant. Charas is the strongest preparation and is made from blooming flowers. Similar in strength to hashish, charas contains a lot of resin.
Cannabis came to the Middle East between 2000 B.C. and 1400 B.C., and it was probably used there by the Scythians, a nomadic Indo-European group. The Scythians also likely carried the drug into southeast Russia and Ukraine, as they occupied both territories for years, according to Warf's report. Germanic tribes brought the drug into Germany, and marijuana went from there to Britain during the 5th century with the Anglo-Saxon invasions.
Cannabis and Pakistan
The only reason cannabis is illegal is because of pressure from the US and the west(as Pakistan gets loan from them so they have to listen to them).
Cannabis will generate a hell of a lot of legit money for Pakistan if it is legalized.
In history, it never had any issues and no ruler ever restricted its use.
It was part and parcel of our culture. Bhang, chars and garda.
There even was a special drink for guests and local gatherings called "Bhang lassi". Combining Bhang and Lassi.
But all these historic use seems to have gone due to the restrictions put on them in the current Era.
