Except you missed how I explained it wasn't any rush responsible for the deep effects of meth, but the time spent with a lot of it pickling those dopamine receptors. So I'm not really disagreeing with you, but if you looked I never claimed a favored ROA. I tend to combine all of them except IV, but actually avoid oral because of severe stomach upset. That said, I do take it bucally, and just try to remember not to swallow for a while.
With excessive use, the "highs" to which I never got much of to begin with, blend together anyway. I find smoking can be relaxing if you have the time, but wastes a lot of dope; at best makes you kind of pleasantly dizzy. Nasal is the best, but obviously is limited by sheer pain. Plugging is ideal, but I need more practice with the intricacies of personal evacuatory processes to make it truly effective, and frankly, I don't have much desire to practice that. To each their own, though.
A further downside to that method, is that it would be bad to get caught smoking, sure, it would be much worse to be caught with my feet touching my ears and my big brown eye winking at my family. And poopy syringes. It is gross, even if the greatest potential. (I have a female friend (it does happen) from another drug forum, who constantly takes it up her butt, and likes to skype me from the bathroom while she waits for it to kick in. So streamlined efficiency is possible with plugging, I'm just not there yet.)
And it's certainly possible to simply eat lots of it, but I'm still siding with that ROA as the source of occasional severe discomfort. I could be wrong and it's less the route than the size of the dose I use with that route. Maybe including a piece of toast is all I need.
But sorry, my child, I wish a couple points orally would be sufficient, but I passed that a while ago.
