I always wonder if it's possible to stone yourself straight. That is to smoke so much weed that you eventually pass all the levels of earthly possible stonedness that the only other alternative is to become straight again.
Well, according to quantum physics, everything has wave-particle duality. Two identical waves cancel each other out if they are in exact half phase of each other (distructive interference).
Thus, if you smoke the EXACT amount of pot that you smoked last cone at EXACTLY the right time, the two stoner waveforms will interact and cause it to collapse, thus leaving you with baseline soberiety.
I tried this with alcohol, but I don't remember if it worked or not. The next thing I knew I was waking up in my friends toilet in a pool of what appeared to be my vomit.
