Will snorting or smoking heroin not cause general public to be addicted?How is snorting or smoking heroin different from injecting it?
The heroin that's snorted/smoked is purer than the ones injected. Snorting or smoking heroin will still cause addiction. Most users who own gotten used to smoking or snorting heroin eventually turn to injecting it to themselves. Just because the heroin isn't injected doesn't mean that it's safe. It's not.
Injection is faster :-)
no...you can get addicted however you try this stuff, purely injecting gives you a more intense hit.
Well let see...
Snorting YOU are using your NOSE, Smoking YOU are using your MOUTH & LUNGS & Injecting it YOU are putting it directly into your VEINS!
ANY / ALL WAYS CAUSE PEOPLE TO BECOME ADDICTED!
actually, snorting and injecting are more alike than smoking it. Snorting it give it direct access to the capillaries surrounded by your nose, thus flowing access to your blood stream and a quick elevated that doesn't last too long. Injecting is even faster, and even shorter. Smoking produces the longest continuing high, but take longer.
All lead to addiction.
when you snort heroin it take approximately two and a half minutes to hold full effect. when you smoke it, it takes a minute, when you shoot it up a capillary it takes around twelve second. snorting it destroys your nasal canal and cartilage inwardly your nose and may be rock-hard to fix eventually. smoking it destroys your alveoli within your lungs. and shooting it up your artery kills white blood cell immediately going away you susceptible to diseases, and don't share needles.
