it's not just that injecting adderall is unsafe. most drug use comes with some sort of health risk especially when you are fucking with needles.
and yea, injecting pills might be more dangerous than injecting drugs prepared specifically for injection such as heroin, but there are still pills out there that i'm willing to take that risk for.
i've IVed generic morphine tablets many times, and i'd probably IV percocets or generic oxycodone if i had the chance as well as other strong opiates.
but adderall is just not worth it IMO. and this is coming from a pretty reckless druggie, so take that into consideration.
i HAVE injected methylphenidate before. i did it because:
a.) i'd just shot up about 80mg of morphine into my arm when i realized that i had a paper due in like 3 hours.
b.) i was needle-happy and extremely stupid.
and it was most definitely not worth the risk that i ran when i acted so recklessly. i DID finish my paper and turn it in on time, but ritalin has no recreational value whatsoever even if you decide to inject it. it makes no difference whether you eat it or inject it, there's really no rush or any sense of euphoria to be gained from IVing it.
adderall in my opinion has minimal recreational value. if you are really sensitive to stimulants, maybe d-amphetamine could potentially produce some sort of a rush, but it's still not worth the risk you run.
if you want to get high off of uppers just get some coke, or meth.
if you want to inject something, try heroin or liquid morphine. heck, if you don't give a shit about your health like me, then go ahead and IV generic morphine tablets or percocets or something if you want. but don't damage your veins for adderall.
