Meth taken orally at an equivalent dose is probably indistinguishable from racemic amphetamine subjectively. At least until you come down, anyway. Meth has a longer half-life. Amphetamine smoked would be the same too, nearly. Maybe slightly slower onset. Negligible difference compared to that provided by smoking versus oral. It's the speed of the come up. The most euphoric part when one takes stimulants orally is usually the first few hours. When rapidly administered, that hits instantly and with full effect and then fades pretty quickly. (So you are very inclined to take another dose an hour or two later.) My advice? You probably don't want to experience it. I've missed it since the first and second and only times I smoked. Realizing I was strongly craving a drug I had used twice is why I got out of that game. Some experiences cannot be unexperienced. There's nothing much interesting about that state, psychologically or intellectually. It's about what you think it might be if you have some experience with stimulants. Just all at once and very hard and you will be awake for two days after. Meth is simply dirty. More neurotoxic than amphetamine and lasts too long. In a perfect world, we'd probably move all the meth addicts onto a supply of Dexedrine. Even if they're high as kites at least their brains will rot more slowly.
