Q

Caffeine

A
  • The activation of numerous neural circuits by caffeine also causes the pituitary gland to secrete hormones that in turn cause the adrenal glands to produce more adrenalin
  • Adrenalin is the “fight or flight” hormone, so it increases your attention level and gives your entire system an extra burst of energy
  • Research indicates that you get some stimulating effect from caffeine intake and any tolerance you build up is minimal
  • Caffeine increases the production of dopamine in the brain’s pleasure circuits, thus helping to maintain the dependency on this drug-average of 90% Canadians
  • Caffeine can create a physical dependency. The symptoms of withdrawal from caffeine begin within one or two days after you stop consuming it
  • Withdrawal symptoms include: Headaches, nausea and sleepiness and affect about ½ people

Q

Nicotine

A
  • Nicotine imitates the action of a natural neurotransmitter called acetylcholine and binds to a particular type of acetylcholine receptor, known as the nicotinic receptor
  • In between nicotine doses, chronic smokers maintain a high enough concentration of nicotine to deactivate the receptors and slow down their recovery. This is why smokers develop a tolerance to nicotine and experience reduced pleasure from it
  • In smokers, repeated nicotine stimulation does increases the amount of dopamine released in the body-reward pathway

Q

How is cocaine used

A
  • Snorted in powder form, through the nostrils, where the drug is absorbed into the bloodstream through the nasal tissues
  • Injected, using a needle and syringe, to release the drug directly into the vein
  • Heated in crystal form and smoked inhaled into the lungs
  • Street dealers dilute cocaine with cornstarch, talcum power or sugar or with other drugs!
  • Crack cocaine is smoked in a glass pipe
  • Powder cocaine is usually snorted or injected (mainlining) or can be rubbed into mucous tissues i.e. gums. Snorting produces a high that is less intense but lasts longer
  • Injecting or smoking cocaine produces a rapid high (rush) because it is absorbed in the blood stream quickly, intensifying its effects

Q

Cocaine’s effect on Dopamine

A
  • Cocaine increases dopamine by preventing dopamine reuptake, leaving more dopamine in the synapse
  • Cocaine binds to the dopamine and does not allow it to recycle. Get dopamine buildup and it floods the synaptic gap. Flood ends after about 30 min. and the person is left yearning to feel as he or she once did

Q

Amphetamines

A
  • Mimic the effect of adrenaline on the body
  • Ritalin, Adderall, Cylert etc

  • WWII, over 72 million tabs were given to soldiers to keep them alert awake and aggressive
  • Highly addictive, develop tolerance very quickly
  • Increase the activity of the monoamine neurotransmitters: serotonin, norepinephrine, and dopamine
  • The drugs stimulate the release of the monoamine neurotransmitters, which leads to elevated levels in the synapses.

18
Q

Bath Salts

A
  • name given to a family of drugs that have one or more manmade chemicals related to cathinone
  • Cathinone is an amphetamine-like stimulant found naturally in the khat plant
  • Common manmade cathinones found in bath salts include 3,4-methylenedioxypyrovalerone (MDPV), mephedrone (“Drone,” “Meph,” or “Meow Meow”), and methylone, but there are many others
  • sold in small plastic or foil packages labeled “Not for Human Consumption”
  • Sometimes labeled as “plant food”—or, more recently, as “jewelry cleaner” or “phone screen cleaner”—they are sold online and in drug product stores.
19
Q

Bath Salts: Effects

A
  • Use of bath salts sometimes causes severe intoxication (a person seems very drunk or “out of it”) and dangerous health effects. There are even reports of people becoming psychotic (losing touch with reality) and violent
  • Produce feelings of joy and increased social interaction and sex drive. These chemicals can also cause people to feel paranoid and nervous and to have hallucinations (see or hear things that are not real).
  • These drugs raise the level of dopamine in brain paths that control reward and movement
  • can also raise heart rate and blood pressure
  • raises brain dopamine in the same way as cocaine but is at least 10 times stronger
20
Q

Steroid hormones

A
  • increase protein synthesis within cells, which results in the buildup of cellular tissue (anabolic), especially in muscle
  • Used therapeutically to stimulate bone growth and appetite, induce male puberty and treat chronic wasting conditions i.e cancer, AIDS
  • Anabolic = promote anabolism (cell growth): protein synthesis from amino acids,
  • increased appetite
  • increased bone remodeling and growth
  • stimulation of bone marrow which increases production of RBC = more muscle cells for more strength
