xxflamexx Reviewed by xxflamexx on . How long does your high last? Im making some "serious" research about the effects of weed, so i would like to know how long the effects last, how much time until the effects peak, and so, for different people. I smoke only hash oil. When its from a pure sativa, its effects peak some 15-30 minutes after smoking, and lasts for some 2-3 hours at most. After it, im 99% sober again. When its from a pure indica, the peak is at some 1-2hours, and last for several hours... i would say some 5-6 until they fade completly. When Rating: 5
