i guess that stuff has gotten really more powerful than it used to be. If you only need a couple of puffs, i guess that could easily last a week, but it depends how much you use and how many times in a day you use it. I sure wish I could buy the stuff that just relaxes, without the THC (that's the hallucination type, right?). There just aren't enough drugs that are truly relaxing if you can't get, or don't want, benzos. And if you can't get opioid pain pills.
