Heroin

Also Known As: smack, horse, big H, junk.

What You Should Know

Heroin comes from the dried milk of the opium poppy, which is also used to create narcotics like codeine and morphine. Heroin can range from a white to dark brown powder to a sticky, tar-like substance. It's injected, smoked, or inhaled. It can give you a burst of euphoria — especially if injected — followed by drowsiness, nausea, stomach cramps, and vomiting.

What's the Problem?

Heroin is ultra-addictive and easy to overdose on.
You'll feel the need to do more heroin as soon as you can just to feel good again.
With long-term use, heroin will destroy your body. It is linked with chronic constipation, dry skin, scarred veins, abscesses and breathing problems.
When you inject heroin, you'll risk collapsed veins and put yourself at risk of deadly infections such as HIV, Hepatitis B or C, and inflammation of the lining of the heart if you share needles.
Heroin causes impotence in guys and irregular periods in girls.
Withdrawal is intense and symptoms include insomnia, vomiting, and muscle pain. Heroin is one of the most difficult drugs to recover from.
