lol. You should do a little history reading. The Hashashi is the sect you are referring to and the name of their group is the origin of both the words 'assassin' and 'hash'. And yes, they were a group of assassins that heavily used cannabis... but they did not use it for focus. Their handlers gave them hash as a reward and as a pacification. The Hashashi were kept in a beautiful palace with wonderful gardens and were kept high on hash perpetually. When the masters wanted the Hashashi to kill someone they would turn off the supply of hash and the Hashashi would do whatever it took to return to their lives of comfort and inebriation. >According to Marco Polo the Hashashin leader "kept at his court boys of twelve years old as seemed to him destined to become courageous men. When the Old Man sent them into the garden in groups of four, ten or twenty, he gave them a certain potion to drink. They slept for three days, then they were carried sleeping into the garden where he had them awakened. > >When these young men woke, and found themselves in the garden with all these marvelous things, they truly believed themselves to be in paradise. And these damsels were always with them in songs and great entertainments; they; received everything they asked for, so that they would never have left that garden of their own will. > >And when the Old Man wished to kill someone, he would take him and say: 'Go and do this thing. I do this because I want to make you return to paradise'. And the assassins go and perform the deed willingly." [ https://hashashin.wikia.org/wiki/Hashish ](https://hashashin.wikia.org/wiki/Hashish) Cannabis slows reaction times and was not used to hone the assassin skills and abilities. This is just a stoner wet dream used to justify debauchery. ...And yes I have smoked weed and enjoy it. Yes it can increase focus but it destroys situational awareness. Don't lie to yourself. Are you one of the stoners that claim that they drive better when high?
