An array of myths and rumors have been circulated about
heroin use. Today’s entry will focus on some frequently asked
questions.
What is Heroin?
-
Derived from Morphine, heroin is classified as part of
the opiate family. It is sold as a brown or white powder, or as a brown/black
tar-like substance
-
Heroin is extremely addictive – Physical dependence can
result after only a week or so of routine use

sense of well being and euphoria
How is Heroin
Administered?
Users administer heroin in one of the following 3 ways:
-
Smoking

Injection
What is Heroin’s
Affect on the Brain?
Heroin works to stimulate the opiate receptors located in
the brain. When someone uses heroin, the substance moves past the blood brain
barrier and fills the brain with opiates. The opiates then engage
neurotransmitter receptors in various areas of the brain in charge of pain and
pleasure regulation. Once the drug has activated these receptors, the users
begin to experience feelings of contentment, euphoria and analgesia.
Over a long enough use period, heroin will begin to alter
the addict’s brain chemistry. Chronic heroin use will ultimately result in a
reduced number of opiate receptors in the brain. As these numbers dwindle, the
user will require more and more heroin to achieve the same initial high.
