Well I spent some time looking it up...
No one really knows but the most common answers are purple haze, marijuana and poppy plant grown togeather, marijuana plant injected with opiate before harvest, really good bud only grown in/near New York, and marijuana plant sprayed with raid throughout the growing process.......
But at this point it doesn't even matter to me any more

(could someone change the name from lift to piff... Or just delete the post. Thanks.)
