I'm going to do the unthinkable here and disagree with PhreeX (but hey, we can both still be correct). I use and abuse dexamphetamine (australian name for dexedrine) 5mg tablets frequently, as I have a hefty 42 pill a week prescription.
Crushing the pills into a fine powder and snorting (rather than swallowing) DOES increase the effects and time to peak action of the drug. Snorting gets more of the drug into your bloodstream (for the same quota), simple.
I find the more immediate come-up of snorting good for noticing the more subtle effects. It's like that famous experiment where if you put a frog in a body of cool water and heat it up slowly, the frog will not try to excape; it doesn't sense a change in perception.. But if you place the frog into a body of immediately hot water, it will try to excape asap.
Danthemanz: I have railed 20 tabs (100mg)in one go (amazing amount of powder to put up my nose!). This quickly turned from heaps of fun (i actually got decent rushes from dex!) into a really annoying and unpleasant 24 hours. Got this irritating body buzz that was not pleasurable at all. Along with headaches, sore joints, tremors, sweating, paranoia. So now my upper limit lies at about 10 (in one go). Ususally don't feel like getting really fucked up on dex tho, I much prefer the cruisy ride of 4 tabs to start and boosting 2 when i start to come down.
Suedama's recipe of the week:
Have a few of your favorite brew (it's better if you dont get totally trashed), and snort some dex. Feeling drugs overtake and work together like this is heaps of fun.
