yes...i've always sensed that this is helpful in explaining why people react differently to different stimuli/substances...

it's not the weed, necessarily, that causes a lack of productivity, but the person him/herself...if a person is a go-getter, the herb may amplify this trait..if the person has a tendecy to be lazy, the herb may amplify the laziness...

too often we blame the ganja, or the gun, when it is the person's mindstate or characteristics that are responsible.
