Drugs are drugs, no matter how you take them. They're a form of escape, the whole rave culture is a form of escape when you get right down to it. Escape isn't bad, we all need to get away from life sometimes and indulge ourselves. The problem begins when escape and self-indulgence becomes your main goal in life. I've never shot up but from what friends of mine have told me, once you use a drug for a certain amount of time and your tolerance has skyrocketed through the roof, the only way to get high is to shoot up. Using this reasoning, the stigma towards shooting up may exist because it represents the later stages of addiction. Also, because this method brings an instant high or "rush", it is likely to be more addictive than the slower methods of ingestion, like snorting. But I became almost instantly addicted to meth and I always only snorted it. So really it depends on the person and their own addictive tendencies. As well, shooting up IS more dangerous if you don't know what you're doing, along with the possibility of transmitting diseases if you don't take proper precautions. In answer to your question, is shooting up taking it too far? Only YOU can answer that for yourself.
