That's what I do. Whenever my tolerance drops to 0 the next few times I smoke I always get very anxeious. but I see that as a good thing because it forces me to confront and think about the things in my life that are upsetting to me. To each their own.
There is a school of thought that I discovered for myself one day on MDMA that says all life here is derived from a single conciousness. I am you and you are me. One life form that simply confused its self with flawed perception of space-time. You are equally everything and individually nothing. The strife and wars of man are nothing but a seemingly outward manifestation of what is wholly an internal conflict of the soul.
I am not like that, I can't smoke my face off anymore, lord knows I have done it before and it wasn't pretty. see I need to not smoke as much like a Jackass, thinking I can handle it when I can't. That might work for you, but not me
