Heroin is a drug that has to be administered very precisely. Not all drugs are like that; sometimes they have a very big ratio between what's safe and what's unsafe. Heroin has to be administered very precisely and that makes it a tricky drug. It also makes it essential that you know what your tolerance is, how much you yourself can take, and it also makes it even more essential that you know the dosage, the purity of what you take. And that's not the case with street heroin. Street heroin is cut; it's diluted by people who do so to make more money. And they don't even know what the concentration it was before they diluted it. So, you never know what you're taking and that makes it risky to use street heroin.
