There must be something wrong with your system. I can smoke a 1/5 of a gram of Super Skunk, over and over and get the same stone for several hours. It is only 15% thc. Some of those white widows can be as much as 25%. I have smoke 8 grams of the SS before in a little over 3 weeks, at 1/5 a gram several times a day, daylight hours, and gotten the same stone ever time. I have heard that if you quit smoking for 5 days out of evermonth you will not have a problem getting stone. I think you ought to see a doctor about that to see if he or she can help you with your problem. Good luck, and happy growing.
