Introduction to substances of abuse Dr. Darwin Telias Maimonides University Ben-Gurion University teliaska@zahav.net.il
“DRUGS” DO NOT EXIST WE CREATE THEM WITH OUR INCORRECT USE OF SUBSTANCES
ALMOST ANY SUBSTANCE MAY BE ABUSED ABUSED SUBSTANCES MAY GIVE PLEASURE OR PAIN OR MAY KILL OR MAIM DEPENDING ON WHATWE DO
SOME EXAMPLES AT HOME: GLUE SPICES LIKE NUTMEG LIGHTERS GAS AIR CONDITIONERS GAS DILUENTS CORRECTION FLUID BANANA ESSENCE
THERE ARE SOME MISCONCEPTIONS ABOUT “DRUGS” “DRUGS” ARE ILLEGAL WRONG! THE MOST ABUSED SUBSTANCES, ALCOHOL AND TOBACCO, ARE LEGAL IN MOST PLACES
“DRUGS” CAUSE “ADDICTION” WRONG MOST SUBSTANCES OF ABUSE DO NOT CAUSE DEPENDENCE THERE IS A SERIOUS DIFFERENCE BETWEEN“ADDICTION”AND“DEPENDENCE”
THE SUBJECT CONTINUES TO USE THE SUBSTANCE BECAUSE HE/SHE LIKES ITS EFFECTS, NO WITHDRAWAL SYNDROME ADDICTION
DEPENDENCE THE SUBJECT CONTINUES USING THE SUBSTANCE BECAUSE HE/SHE IS AFRAID OF THE WITHDRAWAL SYNDROME
VTA HYPOTHALAMUS
ONLY SUBSTANCES THAT MIMICK A NATURALLY-OCCURRING SUBSTANCE IN THE BODY CAN CAUSE DEPENDENCE
OPIOIDS MIMICK “ENDORPHINS”
COCAINE ACTS ON “DOPAMINE”
THC MIMICKS “ANANDAMIDES”
“DRUGS” ARE HARMFUL OR KILL NOT NECESSARILY MANY SUBSTANCES OF ABUSE CAUSE LITTLE OR NO DAMAGE SOME OF THOSE THAT CAUSE DAMAGE DO SO BECAUSE THEY ARE ILLEGAL
WHOEVER USES DRUGS IS STUPID!!
WRONG! NOT EVERYBODY RESPONDS THE SAME TO DRUGS SOME PEOPLE OBTAIN FROM DRUGS SOMETHING THEY DIDN’T HAVE IN THEMSELVES NEUROLOGY EXPLAINS IT
