A true sativa, Sour Haze needs very little time before its starts working. Almost immediately after drawing its thick smoke into their lungs, smokers are struck by a head rush. Temples may begin to throb and salivation may even increase due to increased blood pressure in the head; some also describe a reddening in their cheeks. Soon after acclimating to these new sensations, consumers might notice that their capacity for analytical thinking has increased. Ideas can take on a new intensity and may flow from one to the next in surprising new associations. As such, Sour Haze can enable concentration on complicated, work-related tasks.
