HOW ARE DRUGS MADE?
Drugs can be made synthetically (that means the drug is man-made, by processing chemicals in a laboratory) or organically (that means the drug comes from natural sources like plants). But just because a drug comes from natural source doesn't mean it's safe. Poison ivy grows naturally, but who wants to get too close to that?
Orally: that means through the mouth & eventually into the stomach.
By being smoked or inhaled: through the nose or mouth and then into the lungs.
By being absorbed directly across body tissue- For example, nicotine in chewing tobacco enter through the cheek and guns. And cocaine that is snorted, enter through the lining of the nose.
By being injected into the body- Needles are used to inject drugs intravenously (that means directly into the bloodstream) and intramuscularly ( that means into deep muscles). "Skin-popping" refers to sticking a needle right under the skin.
FAST FACT
Drugs which are inhaled or injected affect the body almost immediately.
WARNING!
Since all of these ways involved putting something foeign into the body, side effects are to be expected. These can range from nausea to infections, permanent body damage, even death. In addition, any time contaminated needles are used, there's an increased risk of transmitting the HIV virus that causes AIDS.
