Narcotic Analgesics

Narcotic Analgesics include a large number of drugs that share three important

characteristics:

• They will relieve pain.

• They will produce withdrawal signs and symptoms, when the drug is stopped after

chronic administration.

• They will suppress the withdrawal signs and symptoms of chronic morphine

administration.

Some drugs classified as Narcotic Analgesics are natural derivatives of opium:

• Heroin

• An important characteristic of narcotic

analgesics is that users develop

tolerance to them

• “Tolerance” means that the same dose of

the drug will produce diminishing effects,

or that a steadily larger dose is needed to

produce the same effects

“Tolerance”

1-28

Tolerance

• An important characteristic of narcotic analgesics is that users develop tolerance to

them. “Tolerance” means that the same dose of the drug will produce diminishing

effects, or that a steadily larger dose is needed to produce the same effects. A

tolerant user who has taken his or her “normal” dose of heroin (for example), may

exhibit little or no evidence of physical impairment.

Inhalants

Inhalants are breathable chemicals that produce mind-altering results.

Inhalants include many familiar household materials, such as glue (“Toluene”), paint,

gasoline, aerosol sprays, etc. that produce volatile fumes.

Some drugs that are classified as Inhalants include:

• Glue (i.e., model airplane glue, Toluene)
