What are some addictive drugs?

for a school health project

which ones are addicting?

Aha. Good question. Now, it all depends on what side of the equation you're working. There are two main types of chemical dependence in the brain: Physical and Psychological.

Physical dependence occurs when the body has become so accustomed to functioning in the presence of a certain chemical that, when removed, the body goes into a physical withdrawal as it attempts to regulate itself. In this time, the body goes through natural physical cravings - as it is easier than having to readjust itself.

Common physically addicting agents:

-Hydrocodone
-Morphine
-Heroin (diacetyl morphine)
>Fatal withdrawals reported
-Hydromorphone (synthetic morphine)
-Oxymorphone
-Oxycodone
-Opium
-Codeine (methylmorphine)
-Dextroamphetamines
-Levoamphetamines
-Alcohol
>Fatal withdrawals reported
-Methyl-amphetamines
>Esp. in HCl form (aka "Crystal meth")
>Fatal withdrawals reported
-Methaqualone (aka "Quaaludes")
-Gamma-hydroxybutyrate (aka "GHB")
>Fatal withdrawals reported
-Cocaine
>Esp. in rock form (aka "Crack")
-Benzodiazepines:
>Alprazolam (aka "Xanax")
>Clonazepam (aka "Klonopin")
>Diazepam (aka "Valium")
>Lorazepam (aka "Ativan")
+All BZOs have seismic withdrawals+
-Phencyclidine (aka "PCP")
-Nicotine
-Thebaine (natural opiate form)
-Carisoprodol (aka "Soma")
--etc.--

Now, if you want extra credit, you could list analogues of these substances. (This is the part in which I beat Andrea's copy-pasted answer...)

Phencyclidine:
-PCPy (Rolicyclidine)
-PCE (Eticyclidine)
-TCP (Tenocyclidine)
-PHP (Phenylcyclohexylpyrrolidine)
-PCPP (Phenylcyclopentylpiperidine)

Morphine:
-dihydromorphine
-dihydrocodeine
-propyl-dimethylmorphine
-isobutyl-dimethylmorphine
-allyl-dimethylmorphine
-cyclopropylmethyl-morphine
-etorphine (aka "Immobilon")
-naloxone (aka "Narcan")
-naltrexone (aka "Trexan")
-levorphanol (aka "LevoDromeran")
-levallorphan (aka "Lorfan")
-cyclorphan
-butorphanol (aka "Stadol")
-benzomorphans
-pentazocine (aka "Talwin")
-cyclazocine
-4-phenylpiperidine (aka "Demerol")
-diphenoxylate (aka "Lomotil")
-ketobemidone
-anileridine
-piminodine
-fentanyl (aka "Sublimaze")
-lofentanil
-propoxyphene (aka "Darvocet")
-6-methylene-dihydromorphine

Okay, sorry - maybe don't use all of them. Morphine has hundreds of analogue derivative compounds. These are just a few from out of my med books. (Yes, I looked up several of them in my school work. No, I'm not being childish.)

Lol. Well, anyways.
