  8. Euphoria Increased alertness Perception of improved self esteem and self confidence Increased body temperature Rapid breathing and heart rate Impulsiveness Methamphetamine Stimulant in amphetamine family Effects- short term Addiction is very likely to occur after 1 use

  9. Meth • Effects are similar to cocaine • Major difference is the half-life • the time required for the activity of a substance taken into the body to lose one half its initial effectiveness • The half-life for cocaine is less than 45 minutes • The half-life for meth is 3-6 hours

  10. Nervousness Irritability Restlessness Insomnia Drastic weight loss Paranoia Desperation Permanent neurological changes Meth Effects- long-term

  11. Meth • Death is possible from overdosing • Even after your brain dies your body can suffer • Elevated body temperature • Cardiovascular shock • Convulsions • Tremors • Death

  12. Ice • Purest methamphetamine • A.k.a. Crank • Compared to crack, the half-life of ice is 60 times longer

  13. Stimulant in amphetamine family Cocaine • Highly addictive drug obtained from the leaves of the coca bush • It can be snorted, smoked or injected • A.k.a. • Coke • Snow • Blow

  14. Cocaine • Leaves are soaked in kerosene and sulfuric acid until they begin to break down to form a paste consisting of 20- 85% of cocaine sulfate is produced • Hydrochloric acid is then used to convert the paste to flakes or rocks of nearly pure cocaine • Colorless or white, odorless powder

  15. How Cocaine is Administered • Can be absorbed through a mucous membrane • Circulated in the blood to heart lungs and other organs • Reaches the brain in about 5 minutes

  16. Cocaine Administration • Inhaled • Reaches the brain and nervous system in 3 minutes • Effects peak in 15-20 minutes and disappear in 60-90 minutes

  17. Cocaine Administration • Injected into a vein • Reaches brain in 15 seconds • 100% absorption of drug • “High” crests in 3-5 minutes and lasts 30-40 minutes • Smoked • Reaches brain in 7 seconds

  18. Freebase • Freebase is the purified base form of cocaine processed from the paste using volatile (evaporating rapidly; passing off readily in the form of vapor) chemicals • The wisps of smoke produced are inhaled a.k.a. ‘chasing the dragon’ as when used with heroin

  19. Initial Effects of Cocaine • Effects are similar to amphetamine • Studies couldn’t distinguish between the effects of the 2 in small doses except that amphetamine’s actions are longer lasting

  20. Cocaine is a vasoconstrictor Narrows the blood vessels Appetite is deadened Cannot sleep Temperature may rise or fall Heart rate, blood pressure and breathing speed up Metabolism is sped up Initial Effects of Cocaine

  21. Confusion Anxiety Depression Short-tempered Lose interest in food Aggressive Thinking impaired Difficulty concentrating and remembering Long-term Effects

  22. Long term Effects • Cocaine psychosis • Have delusions and become paranoid • Visual, auditory or tactile hallucinations • Most common is formication- the sensation of bugs crawling under the skin • Can last days, weeks, even months

  24. Other Risk • Intravenous users risk: • Hepatitis • HIV • Other blood borne diseases • Freebase smokers • Lung damage • Mucous membranes • Cilia • Elasticity

  25. Crack • Named for the sound it makes when it is smoked • Almost pure cocaine • Most accessible and powerful form of cocaine • Works faster than other forms • Takes about 7 seconds to reach the brain

  26. Crack • Acts as stimulant and local anestthetgic • Hyper-aroused state in which the user experiences • a decrease in appetite • Rapid breathing • Tingling in the fingers • Sense of well-being • Lowered anxiety
