Rx amphetamines are completely a waste if you are Snorting it, or attempting to Shoot it, Orally or Plugging is the beat way to go, you get the maximum duration, most positive quality effects VS sniffing it or Shooting, where it will leave u feeling coke'd out and feignished, and will not last long at all. I have IVed IR Ritalin, i have IVed Dexedrine 15m Spansules (I crushed the beads into a fine powder, and injected it) i got a very very SHORT LIVED INTENSE RUSH which lasted 3 seconds, it actually was a rush that was DYSPHORIC, i fell to the ground, in a panic, thinking i was going to have a heart attack, i crawled into to the bathroom pouring cold water all over my body shaking, and i as geeked in a HORRIBLE WAY for a long time, when i IVed Ritalin, in NO way it wa snot even close to IV cocaine, IVing Ritalin felt like taking it orally except it kicked in within1 minute, its a complete waste shooting RX amphetamines, if it's not in HCL form, its not worth doing! Oral Amphetamine/ or Plugging is the only way u will get the real magic effects of amphetamines, snorting or shooting totally bypasses it's magical effects, causing a coke'd out uncomofrtable hypertensive state. i DO NOT RECOMMEND THIS
