Other - amph dont get swim high any more :(

[desperado]

For the past few month SWIm was getting few grams of cheap UK street amph of like 10 different people and different speed . But it dont do anything to SWIM when he takes it sober... it only has some effect when SWIM takes it with MDMA, it makes mdma effect last longer.
SWIm got pissed off after first few times coz it didnt do anything, so he had a full gram of it at once just to see whats gonna happen, and NOTHING happend, just hands got a bit sweaty and very dry mouth. So it only has some sort of effect when he takes it with MDMA. But it does absolutely nothing when SWIM takes it sober. Even once just to test it again SWIM had more then a half of a gram in the morning when he was tired just to see if its gonna do anything, and it didnt... swim was still tired, had massive breakfast and went to work.
And that was 100% amph, cheap UK street amph but still... it must do atlist something ?? SWIM very confused.
Is there any other ways to take get high of amph ??? maybe smoking it ??? if so tell how please. Thx
